## Chapter 1. Introduction

RichFaces is an open source framework that adds Ajax capability into existing JSF applications without resorting to JavaScript.

RichFaces leverages JavaServer Faces framework including lifecycle, validation, conversion facilities and management of static and dynamic resources. RichFaces components with built-in Ajax support and a highly customizable look-and-feel can be easily incorporated into JSF applications.

RichFaces allows to:

- Intensify the whole set of JSF benefits while working with Ajax. RichFaces is fully integrated into the JSF lifecycle. While other frameworks only give you access to the managed bean facility, RichFaces advantages the action and value change listeners, as well as invokes server-side validators and converters during the Ajax request-response cycle.

- Add Ajax capability to the existing JSF applications. Framework provides two components libraries (Core Ajax and UI). The Core library sets Ajax functionality into existing pages, so there is no need to write any JavaScript code or to replace existing components with new Ajax ones. RichFaces enables page-wide Ajax support instead of the traditional component-wide support and it gives the opportunity to define the event on the page. An event invokes an Ajax request and areas of the page which become synchronized with the JSF Component Tree after changing the data on the server by Ajax request in accordance with events fired on the client.

- Create quickly complex View basing on out of the box components. RichFaces UI library contains components for adding rich user interface features to JSF applications. It extends the RichFaces framework to include a large (and growing) set of powerful rich Ajax-enabled components that come with extensive skins support. In addition, RichFaces components are designed to be used seamlessly with other 3d-party component libraries on the same page, so you have more options for developing your applications.

- Write your own custom rich components with built-in Ajax support. We're always working on improvement of Component Development Kit (CDK) that was used for RichFaces UI library creation. The CDK includes a code-generation facility and a templating facility using a JSP-like syntax. These capabilities help to avoid a routine process of a component creation. The component factory works like a well-oiled machine allowing the creation of first-class rich components with built-in Ajax functionality even more easily than the creation of simpler components by means of the traditional coding approach.

- Package resources with application Java classes. In addition to its core, Ajax functionality of RichFaces provides an advanced support for the different resources management: pictures, JavaScript code, and CSS stylesheets. The resource framework makes possible to pack easily these resources into Jar files along with the code of your custom components.

- Easily generate binary resources on-the-fly. Resource framework can generate images, sounds, Excel spreadsheets etc.. on-the-fly so that it becomes for example possible to create images using the familiar approach of the "Java Graphics2D" library.

- Create a modern rich user interface look-and-feel with skins-based technology. RichFaces provides a skinnability feature that allows easily define and manage different color schemes and other parameters of the UI with the help of named skin parameters. Hence, it is possible to access the skin parameters from JSP code and the Java code (e.g. to adjust generated on-the-fly images based on the text parts of the UI). RichFaces comes with a number of predefined skins to get you started, but you can also easily create your own custom skins.

- Test and create the components, actions, listeners, and pages at the same time. An automated testing facility is in our roadmap for the near future. This facility will generate test cases for your component as soon as you develop it. The testing framework will not just test the components, but also any other server-side or client-side functionality including JavaScript code. What is more, it will do all of this without deploying the test application into the Servlet container.

RichFaces UI components come ready to use out-of-the-box, so developers save their time and immediately gain the advantage of the mentioned above features in Web applications creation. As a result, usage experience can be faster and easily obtained.

## Chapter 3. Getting Started with RichFaces

## 3.1. Downloading RichFaces 3.2.1

The latest release of RichFaces is available for download at:

http://labs.jboss.com/jbossrichfaces/downloads

in the RichFaces project area under JBoss.

## 3.2. Installation

- Unzip "richfaces-ui-3.2.1.GA-bin.zip" file to the chosen folder.

- Copy `"richfaces-api-3.2.1.jar"`, `"richfaces-impl-3.2.1.jar"`,`"richfaces-ui-3.2.1.jar"`files into the "WEB-INF/lib" folder of your application.

- Add the following content into the "WEB-INF/web.xml" file of your application:

      ...

          <context-param>

              <param-name>org.richfaces.SKIN</param-name>

              <param-value>blueSky</param-value>

          </context-param>

          <filter>

              <display-name>RichFaces Filter</display-name>

              <filter-name>richfaces</filter-name>

              <filter-class>org.ajax4jsf.Filter</filter-class>

          </filter>

          <filter-mapping>

              <filter-name>richfaces</filter-name>

              <servlet-name>Faces Servlet</servlet-name>

              <dispatcher>REQUEST</dispatcher>

              <dispatcher>FORWARD</dispatcher>

              <dispatcher>INCLUDE</dispatcher>

          </filter-mapping>

- Add the following lines for each JSP page of your application.

      <%@ taglib uri="http://richfaces.org/a4j" prefix="a4j"%>

      <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%>

  For XHTML pages:

      <xmlns:a4j="http://richfaces.org/a4j">

      <xmlns:rich="http://richfaces.org/rich">

## 3.3. Simple Ajax Echo Project

In our JSF project you need only one JSP page that has a form with a couple of child tags: <h:inputText> and <h:outputText> .

This simple application let you input some text into the <h:inputText> , send data to the server, and see the server response as a value of <h:outputText> .

### 3.3.1. JSP Page

Here is the necessary page (echo.jsp):

        <%@ taglib uri="http://richfaces.org/a4j" prefix="a4j"%>

        <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%>

        <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>

        <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>

        <html>

          <head>

            <title>repeater </title>

          </head>

          <body>

            <f:view>

              <h:form>

                  <rich:panel header="Simple Echo">

                    <h:inputText size="50" value="#{bean.text}" >

                      <a4j:support event="onkeyup" reRender="rep"/>

                    </h:inputText>

                    <h:outputText value="#{bean.text}" id="rep"/>

                  </rich:panel>

              </h:form>

            </f:view>

          </body>

        </html>

Only two tags distinguish this page from a "regular" JSF one. There are <rich:panel> and <a4j:support> .

The <rich:panel> allows to place the page elements in rectangle panel that can be skinned.

The <a4j:support> with corresponding attributes (as it was shown in the previous example) adds an Ajax support to the parent <h:inputText> tag. This support is bound to "onkeyup" JavaScript event, so that each time when this event is fired on the parent tag, our application sends an Ajax request to the server. It means that the text field pointed to our managed bean property contains up-to-date value of our input.

The value of "reRender" attribute of the <a4j:support> tag defines which part(s) of our page is (are) to be updated. In this case, the only part of the page to update is the <h:outputText> tag because its ID value matches to the value of "reRender" attribute. As you see, it's not difficult to update multiple elements on the page, only list their IDs as the value of "reRender" .

### 3.3.2. Data Bean

In order to build this application, you should create a managed bean:

    package demo;

            public class Bean {

            private String text;

            public Bean() {

            }

            public String getText() {

            return text;

            }

            public void setText(String text) {

            this.text = text;

            }

            }

### 3.3.3. faces-config.xml

Next, it's necessary to register your bean inside of the faces-config.xml file:

        <?xml version="1.0" encoding="UTF-8"?>

        <!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD  JavaServer Faces Config 1.1//EN"

        "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">

        <faces-config>

          <managed-bean>

            <managed-bean-name>bean</managed-bean-name>

            <managed-bean-class>demo.Bean</managed-bean-class>

            <managed-bean-scope>request</managed-bean-scope>

            <managed-property>

              <property-name>text</property-name>

              <value/>

            </managed-property>

          </managed-bean>

        </faces-config>

## Note:

Nothing that relates directly to RichFaces is required in the configuration file.

### 3.3.4. Web.xml

It is also necessary to add jar files (see installation chapter) and modify the "web.xml" file:

        <?xml version="1.0"?>

        <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee  http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

        <display-name>a4jEchoText</display-name>

        <context-param>

            <param-name>org.richfaces.SKIN</param-name>

            <param-value>blueSky</param-value>

        </context-param>

        <context-param>

            <param-name>javax.faces.STATE_SAVING_METHOD</param-name>

            <param-value>server</param-value>

        </context-param>

        <filter>

            <display-name>RichFaces Filter</display-name>

            <filter-name>richfaces</filter-name>

            <filter-class>org.ajax4jsf.Filter</filter-class>

        </filter>

        <filter-mapping>

            <filter-name>richfaces</filter-name>

            <servlet-name>Faces Servlet</servlet-name>

            <dispatcher>REQUEST</dispatcher>

            <dispatcher>FORWARD</dispatcher>

            <dispatcher>INCLUDE</dispatcher>

        </filter-mapping>

        <listener>

            <listener-class>com.sun.faces.config.ConfigureListener</listener-class>

        </listener>

        <!-- Faces Servlet -->

        <servlet>

            <servlet-name>Faces Servlet</servlet-name>

            <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>

            <load-on-startup>1</load-on-startup>

        </servlet>

        <!-- Faces Servlet Mapping -->

        <servlet-mapping>

            <servlet-name>Faces Servlet</servlet-name>

            <url-pattern>*.jsf</url-pattern>

        </servlet-mapping>

        <login-config>

            <auth-method>BASIC</auth-method>

        </login-config>

        </web-app>

Now your application should work.

### 3.3.5. Deployment

Finally, you should be able to place this application on your Web server.To start your project, point your browser at http://localhost:8080/a4jEchoText/echo.jsf

## Chapter 4. Settings for different environments

RichFaces comes with support for all tags (components) included in the JavaServer Faces specification. To add RichFaces capabilities to the existing JSF project you should just put the RichFaces libraries into the lib folder of the project and add filter mapping. The behavior of the existing project doesn't change just because of RichFaces.

## 4.1. Web Application Descriptor Parameters

RichFaces doesn't require any parameters to be defined in your web.xml. But the RichFaces parameters listed below may help with development and may increase the flexibility of RichFaces usage.

Table 4.1. Initialization Parameters

Name | Default | Description
--- | --- | ---
org.richfaces.SKIN | DEFAULT | Is a name of a skin used in an application. It can be a literal string with a skin name, or the EL expression (`#{...}`) pointed to a String property (skin name) or a property of a org.richfaces.framework.skin type. Skin in last case, this instance is used as a current skin
org.richfaces.LoadScriptStrategy | DEFAULT | Defines how the RichFaces script files are loaded to application. Possible values are: ALL, DEFAULT, NONE. For more information see "Scripts and Styles Load Strategy".
org.richfaces.LoadStyleStrategy | DEFAULT | Defines how the RichFaces style files are loaded to application. Possible values are: ALL, DEFAULT, NONE. For more information see "Scripts and Styles Load Strategy".
org.ajax4jsf.LOGFILE | none | Is an URL to an application or a container log file (if possible). If this parameter is set, content from the given URL is shown on a Debug error page in the iframe window
org.ajax4jsf.VIEW_HANDLERS | none | Is a comma-separated list of custom ViewHandler instances for inserting in chain. Handlers are inserted BEFORE RichFaces viewhandlers in the given order. For example, in facelets application this parameter must contain com.sun.facelets.FaceletViewHandler, instead of declaration in faces-config.xml
org.ajax4jsf.CONTROL_COMPONENTS | none | Is a comma-separated list of names for a component as a special control case, such as messages bundle loader, alias bean components, etc. Is a type of component got by a reflection from the static field COMPONENT_TYPE . For components with such types encode methods always are called in rendering Ajax responses, even if a component isn't in an updated part
org.ajax4jsf.ENCRYPT_RESOURCE_DATA | false | For generated resources, such as encrypt generation data, it's encoded in the resource URL. For example, URL for an image generated from the mediaOutput component contains a name of a generation method, since for a hacker attack, it is possible to create a request for any JSF baked beans or other attributes. To prevent such attacks, set this parameter to "true" in critical applications (works with JRE > 1.4 )
org.ajax4jsf.ENCRYPT_PASSWORD | random | Is a password for encryption of resources data. If isn't set, a random password is used
org.ajax4jsf.COMPRESS_SCRIPT | true | It doesn't allow framework to reformat JavaScript files (makes it impossible to debug)
org.ajax4jsf.RESOURCE_URI_PREFIX | a4j | Defines prefix which is added to all URIs of generated resources. This prefix designed to handle RichFaces generated resources requests
org.ajax4jsf.GLOBAL_RESOURCE_URI_PREFIX | a4j/g | Defines prefix which is added to URIs of global resources. This prefix designed to handle RichFaces generated resources requests
org.ajax4jsf.SESSION_RESOURCE_URI_PREFIX | a4j/s | Defines prefix which is used for session tracking for generated resources. This prefix designed to handle RichFaces generated resources requests
org.ajax4jsf.DEFAULT_EXPIRE | 86400 | Defines in seconds how long streamed back to browser resources can be cached
org.ajax4jsf.SERIALIZE_SERVER_STATE | false | If enabled the component state (not the tree) will be serialized before being stored in the session. This may be desirable for applications that may have issues with view state being sensitive to model changes. Instead of this parameter can use `com.sun.faces.serializeServerState` and `org.apache.myfaces.SERIALIZE_STATE_IN_SESSION` parameters for corresponding environments.

## Note:

`org.richfaces.SKIN` is used in the same way as `org.ajax4jsf.SKIN`

Table 4.2. org.ajax4jsf.Filter Initialization Parameters

Name | Default | Description
--- | --- | ---
log4j-init-file | - | Is a path (relative to web application context) to the log4j.xml configuration file, it can be used to setup per-application custom logging
enable-cache | true | Enable caching of framework-generated resources (JavaScript, CSS, images, etc.). For debug purposes development custom JavaScript or Style prevents to use old cached data in a browser
forceparser | true | Force parsing by a filter HTML syntax checker on any JSF page. If "false", only Ajax responses are parsed to syntax check and conversion to well-formed XML. Setting to "false" improves performance, but can provide visual effects on Ajax updates

## 4.2. Sun JSF RI

RichFaces works with implementation of JSF (JSF 1.2) and with most JSF component libraries without any additional settings. For more information look at:

java.sun.com

Additional information how to get `ViewExpiredExceptions` when using RichFaces with JSF 1.2 you can find here.

## 4.3. Apache MyFaces

RichFaces works with Apache MyFaces 1.2 version including specific libraries like TOMAHAWK Sandbox and Trinidad (the previous ADF Faces). However, there are some considerations to take into account for configuring applications to work with MyFaces and RichFaces.

There are some problems with different filters defined in the web.xml file clashing. To avoid these problems, the RichFaces filter must be the first one among other filters in the web.xml configuration file.

For more information look at: http://myfaces.apache.org

There's one more problem while using MyFaces + Seam . If you use this combination you should use <a4j:page> inside <f:view> (right after it in your code) wrapping another content inside your pages because of some problems in realization of <f:view> in myFaces.

The problem is to be overcome in the nearest future.

## 4.4. Facelets Support

A high-level support for Facelets is one of our main support features. When working with RichFaces, there is no difference what release of Facelets is used.

You should also take into account that some JSF frameworks such as Facelets use their own `ViewHandler` and need to have it first in the chain of ViewHandlers and the RichFaces AjaxViewHandler is not an exception. At first RichFaces installs its ViewHandler in any case, so in case of two frameworks, for example RichFaces + Facelets, no changes in settings are required. Although, when more then one framework (except RichFaces) is used, it's possible to use the `VIEW_HANDLERS` parameter defining these frameworks view handlers according to its usage order in it. For example, the declaration:

Example:

                <context-param>

                <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>

                <param-value>com.sun.facelets.FaceletViewHandler</param-value>

                </context-param>

says that Facelets will officially be the first, however `AjaxViewHandler` will be a little ahead temporarily to do some small, but very important job.

## Note:

In this case you don't have to define `FaceletViewHandler` in the WEB-INF/faces-config.xml.

## 4.5. JBoss Seam Support

RichFaces now works out-of-the-box with JBoss Seam and Facelets running inside JBoss AS 4.0.4 and higher. There is no more shared JAR files needed. You just have to package the RichFaces library with your application.

Your web.xml for Seam 1.2 must be like this:

    <?xml version="1.0" ?>

    <web-app xmlns="http://java.sun.com/xml/ns/j2ee"

            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Seam 2 supports RichFaces Filter. Thus your web.xml for Seam 2 must be like this:

    <?xml version="1.0" encoding="UTF-8"?>

    <web-app version="2.5"

    </web-app>

Only one issue still persists while using Seam with MyFaces. Look at myFaces part of this section.

## 4.6. Portlet Support

JBoss Portlets have support since version Ajax4jsf 1.1.1. This support is improved in RichFaces 3.2.1. Provide your feedback on compatible with RichFaces if you face some problems.

## 4.7. Sybase EAServer

The load-on-startup for the Faces Servlet had to be set to 0 in web.xml.

Example:

    ...

          <servlet>

              <servlet-name>Faces Servlet</servlet-name>

              <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>

              <load-on-startup>0</load-on-startup>

        </servlet>

    ...

This is because, EAServer calls servlet `init()` before the `ServletContextInitializer`. Not an EAServer bug, this is in Servlet 2.3 spec.

## 4.8. Oracle AS/OC4J

In order to deploy your project with RichFaces components to an Oracle AS you just have to prevent the application's class loader from importing the Oracle XML parser. Use the following notation in orion-application.xml :

    ...

    <imported-shared-libraries>

            <remove-inherited name="oracle.xml"/>

            <remove-inherited name="oracle.xml.security"/>

    </imported-shared-libraries>

    ...

## Chapter 5. Basic concepts of the RichFaces Framework

## 5.1. Introduction

The framework is implemented as a component library which adds Ajax capability into existing pages, so you don't need to write any JavaScript code or to replace existing components with new Ajax widgets. RichFaces enables page-wide Ajax support instead of the traditional component-wide support. Hence, you can define the event on the page that invokes an Ajax request and the areas of the page that should be synchronized with the JSF Component Tree after the Ajax request changes the data on the server according to the events fired on the client.

Next Figure shows how it works:

Figure 5.1. Request Processing flow

RichFaces allows to define (by means of JSF tags) different parts of a JSF page you wish to update with an Ajax request and provide a few options to send Ajax requests to the server. Also JSF page doesn't change from a "regular" JSF page and you don't need to write any JavaScript or XMLHTTPRequest objects by hands, everything is done automatically.

## 5.2. RichFaces Architecture Overview

Next figure lists several important elements of the RichFaces framework

Figure 5.2. Core Ajax component structure

##### Ajax Filter.

To get all benefits of RichFaces , you should register a Filter in web.xml file of your application. The Filter recognizes multiple request types. Necessary information about Filter configuration can be found in the "Filter configuration" section. The sequence diagram on Figure 3 shows the difference in processing of a "regular" JSF request and an Ajax request.

In the first case the whole JSF tree will be encoded, in the second one option it depends on the "size" of the Ajax region. As you can see, in the second case the filter parses the content of an Ajax response before sending it to the client side.

Have a look at the next picture to understand these two ways:

Figure 5.3. Request Processing sequence diagram

In both cases, the information about required static or dynamic resources that your application requests is registered in the ResourseBuilder class.

When a request for a resource comes (Figure 4), the RichFaces filter checks the Resource Cache for this resource and if it is there, the resource is sent to the client. Otherwise, the filter searches for the resource among those that are registered by the ResourceBuilder. If the resource is registered, the RichFaces filter will send a request to the ResourceBuilder to create (deliver) the resource.

Next Figure shows the ways of resource request processing.

Figure 5.4. Resource request sequence diagram

##### AJAX Action Components

There are Ajax Action Components: <a4j:commandButton> , <a4j:commandLink> , <a4j:poll> and <a4j:support> and etc. You can use them to send Ajax requests from the client side.

##### AJAX Containers

AjaxContainer is an interface that describes an area on your JSF page that should be decoded during an Ajax request. `AjaxViewRoot` and `AjaxRegion` are implementations of this interface.

##### JavaScript Engine

RichFaces JavaScript Engine runs on the client-side. It knows how to update different areas on your JSF page based on the information from the Ajax response. Do not use this JavaScript code directly, as it is available automatically.

## 5.3. Limitations and Rules

In order to create RichFaces applications properly, keep the following points in mind:

- Any Ajax framework should not append or delete, but only replace elements on the page. For successful updates, an element with the same ID as in the response must exist on the page. If you'd like to append any code to a page, put in a placeholder for it (any empty element). For the same reason, it's recommended to place messages in the "AjaxOutput" component (as no messages is also a message).

- Don't use <f:verbatim> for self-rendered containers, since this component is transient and not saved in the tree.

- Ajax requests are made by XMLHTTPRequest functions in XML format, but this XML bypasses most validations and the corrections that might be made in a browser. Thus, create only a strict standards-compliant code for HTML and XHTML, without skipping any required elements or attributes. Any necessary XML corrections are automatically made by the XML filter on the server, but lot's of unexpected effects can be produced by an incorrect HTML code.

- The RichFaces ViewHandler puts itself in front of the Facelets ViewHandlers chain.

- RichFaces components uses their own renderers. On the Render Response Phase RichFaces framework makes a traversal of the component tree, calls its own renderer and put the result into the Faces Response.

## 5.4. Ajax Request Optimization

### 5.4.1. Re-Rendering

Ajax attributes are common for Ajax components such as <a4j:support> , <a4j:commandButton> , <a4j:jsFunction> , <a4j:poll> , <a4j:push> and so on. Also, most RichFaces components with built-in Ajax support have these attributes for a similar purpose. Ajax components attributes help RichFaces to expose its features. Most of the attributes have default values. Thus, you can start working with RichFaces without knowing the usage of these attribute. However, their usage allows to tune the required Ajax behavior very smoothly.

"reRender" is a key attribute. The attribute allows to point to area(s) on a page that should be updated as a response on Ajax interaction. The value of the "reRender" attribute is an id of the JSF component or an id list.

A simple example is placed below:

    ...

            <a4j:commandButton value="update" reRender="infoBlock"/>

                ...

            <h:panelGrid id="infoBlock">

                ...

            </h:panelGrid>

    ...

The value of "reRender" attribute of the <a4j:commandButton> tag defines which part(s) of your page is (are) to be updated. In this case, the only part of the page to update is the <h:panelGrid> tag because its ID value matches to the value of "reRender" attribute. As you see, it's not difficult to update multiple elements on the page, only list their IDs as the value of "reRender" .

"reRender" uses UIComponent.findComponent() algorithm (with some additional exceptions) to find the component in the component tree. As can you see, the algorithm presumes several steps. Each other step is used if the previous step is not successful. Therefore, you can define how fast the component is found mentioning it more precisely. The following example shows the difference in approaches (both buttons will work successfully):

    ...

        <h:form id="form1">

            ...

            <a4j: commandButton value="Usual Way" reRender="infoBlock, infoBlock2" />

            <a4j:commandButton value="Shortcut" reRender=":infoBlockl,:sv:infoBlock2" />

            ...

        </h:form>

        <h:panelGrid id="infoBlock">

            ...

        </h:panelGrid>

        ...

        <f:subview id="sv">

          <h:panelGrid id="infoBlock2">

            ...

          </h:panelGrid>

          ...

        </f:subview>

    ...

It's also possible to use JSF EL expression as a value of the reRender attribute. It might be a property of types Set, Collection, Array or simple String. The EL for reRender is resolved right before the Render Response phase. Hence, you can calculate what should be re-rendered on any previous phase during the Ajax request processing.

Most common problem with using reRender is pointing it to the component that has a "rendered" attribute. Note, that JSF does not mark the place in the browser DOM where the outcome of the component should be placed in case the "rendered" condition returns false. Therefore, after the component becomes rendered during the Ajax request, RichFaces delivers the rendered code to the client, but does not update a page, because the place for update is unknown. You need to point to one of the parent components that has no "rendered" attribute. As an alternative, you can wrap the component with <a4j:outputPanel> `layout="none"` .

"ajaxRendered" attribute of the <a4j:outputPanel> set to "true" allows to define the area of the page that will be re-rendered even if it is not pointed in the reRender attribute explicitly. It might be useful if you have an area on a page that should be updated as a response on any Ajax request. For example, the following code allows to output error messages regardless of what Ajax request causes the Validation phase failed.

    ...

         <a4j:outputPanel ajaxRendered="true">

            <h:messages />

        </a4j:outputPanel>

    ...

"limitToList" attribute allows to dismiss the behavior of the <a4j:outputPanel> "ajaxRendered" attribute. `limitToList = "false"` means to update only the area(s) that mentioned in the "reRender" attribute explicitly. All output panels with `ajaxRendered="true"` is ignored. An example is placed below:

    ...

        <h:form>

           <h:inputText value="#{person.name}">

                <a4j:support event="onkeyup" reRender="test" limitToList="true"/>

            </h:inputText>

            <h:outputText value="#{person.name}" id="test"/>

        </form>

    ...

### 5.4.2. Queue and Traffic Flood Protection

"eventsQueue" attribute defines the name of the queue that will be used to order upcoming Ajax requests. By default, RichFaces does not queue Ajax requests. If events are produced simultaneously, they will come to the server simultaneously. JSF implementations (especially, the very first ones) does not guaranty that the request that comes first will be served or passed into the JSF lifecycle first. The order how the server side data will be modified in case of simultaneous request might be unpredictable. Usage of eventsQueue attribute allows to avoid possible mess. Define the queue name explicitly, if you expect intensive Ajax traffic in your application.

The next request posted in the same queue will wait until the previos one is not processed and Ajax Response is returned back if the "eventsQueue" attribute is defined. In addition, RichFaces starts to remove from the queue "similar" requests. "Similar'"requests are the requests produced by the same event. For example, according to the following code, only the newest request will be sent to the server if you type very fast and has typed the several characters already before the previous Ajax Response is back.

    ...

        <h:inputText value="#{userBean.name}">

            <a4j:support event="onkeyup" eventsQueue="foo" reRender="bar" />

        </h:inputText>

    ...

"requestDelay" attribute defines the time (in ms) that the request will be wait in the queue before it is ready to send. When the delay time is over, the request will be sent to the server or removed if the newest "similar" request is in a queue already .

"ignoreDupResponses" attribute orders to ignore the Ajax Response produced by the request if the newest "similar" request is in a queue already. `ignoreDupResponses"="true"` does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response loses the actuality.

Defining the "eventsQueue" along with "requestDelay" allows to protect against unnecessary traffic flood and synchronizes Ajax requests order. If you have several sources of Ajax requests, you can define the same queue name there. This might be very helpful if you have Ajax components that invoke request asynchronously from the ones produced by events from users. For example, <a4j:poll> or <a4j:push> . In case the requests from such components modify the same data, the synchronization might be very helpful.

More information can be found on the RichFaces Users Forum .

"timeout" attribute is used for setting response waiting time on a particular request. If a response is not received during this time, the request is aborted.

### 5.4.3. Data Processing Options

RichFaces uses form based approach for Ajax request sending. This means each time, when you click an Ajax button or <a4j:poll> produces an asynchronous request, the data from the closest JSF form is submitted with the XMLHTTPRequest object. The form data contains the values from the form input element and auxiliary information such as state saving data.

When "ajaxSingle" attribute value is "true" , it orders to include only a value of the current component (along with <f:param> or <a4j:action> param values if any) to the request map. In case of <a4j:support> , it is a value of the parent component. An example is placed below:

    ...

        <h:form>

            <h:inputText value="#{person.name}">

                <a4j:support event="onkeyup" reRender="test" ajaxSingle="true"/>

            </h:inputText>

          <h:inputText value="#{person.middleName}"/>

        </form>

    ...

In this example the request contains only the input component causes the request generation, not all the components contained on a form, because of `ajaxSingle="true"` usage.

Note, that `ajaxSingle="true"` reduces the upcoming traffic, but does not prevent decoding other input components on the server side. Some JSF components, such as <h:selectOneMenu> do recognize the missing data in the request map value as a null value and try to pass the validation process with a failed result. Thus, use <a4j:region> to limit a part of the component tree that will be processed on the server side when it is required.

"immediate" attribute has the same purpose as any other non-JSF component. The default "ActionListener" should be executed immediately (i.e. during the Apply Request Values phase of a request processing lifecycle), rather than waiting until the Invoke Application phase. Using `immediate="true"` is one of the ways to have some data model values updated when other cannot be updated because of a problem with passing the Validation phase successfully. This might be important inside the <h:dataTable> like components where using <a4j:region> is impossible due to the <h:dataTable> component architecture.

"bypassUpdates" attribute allows to bypass the Update Model phase. It might be useful if you need to check your input against the available validator, but not to update the model with those data. Note, that an action will be invoked at the end of the Validation phase only if the Validation phase is passed successfully. The listeners of the Application phase will not be invoked in any case.

### 5.4.4. Action and Navigation

Ajax component is similar to any other non-Ajax JSF component like <h:commandButton> . It allows to submit the form. You can use "action" and "actionListener" attributes to invoke the action method and define the action event.

"action" method must return null if you want to have an Ajax Response with a partual page update. This is regular mode called `"Ajax request generates Non-Ajax Response"`. In case of action does not return null, but the action outcome that matches one of navigation rules, RichFaces starts to work in `"Ajax request generates Non-Ajax Response"` mode. This mode might be helpful in two major cases:

- RichFaces allows to organize a page flow inside the <a4j:include> component. This is a typical scenario for Wizard like behavior. The new content is rendered inside the <a4j:include> area. The content is taken from the navigation rule of the faces configuration file (usually, the faces-config.xml). Note, that the content of the "wizard" is not isolated from the rest of the page. The included page should not have own <f:view> (it does not matter if you use facelets). You need to have an Ajax component inside the <a4j:include> to navigate between the wizard pages. Otherwize, the whole page update will be performed.

- If you want to involve the server side validators and navigate to the next page only if the Validation phase is passed successfully, you can replace <h:commandButton> with <a4j:commandButton> and point to the action method that navigates to the next page. If Validation process fails, the partial page update will occur and you will see an error message. Otherwize, the application proceeds to the next page. Make sure, you define <redirect/> option for the navigation rule to avoid memory leaks.

### 5.4.5. JavaScript Interactions

RichFaces allows writing Ajax-enabled JSF application without writing any Javascript code. However, you can still invoke the JavaScript code if you need. There are several ajax attributes that helps to do it.

"onsubmit" attribute allows to invoke JavaScript code before an Ajax request is sent. If "onsubmit" returns "false" , the Ajax request is canceled. The code of "onsubmit" is inserted before the RichFaces Ajax call. Hence, the "onsubmit" should not has a "return" statement if you want the Ajax request to be sent. If you are going to invoke a JavaScript function that returns "true" or "false" , use the conditional statement to return something only when you need to cancel the request. For example:

    ...

        onsubmit="if (mynosendfunct()==false){return false}"

    ...

"onclick" attribute is similar to the "onsubmit" , but for clickable components such as <a4j:commandLink> and <a4j:commandButton> . If it returns "false" , the Ajax request is canceled also.

"oncomplete" attribute allows to invoke the JavaScript code right after the Ajax Response is returned back and the DOM tree of the browser is updated. RichFaces registers the code for further invocation of XMLHTTP request object before an Ajax request is sent. This means the code will not be changed during processing of the request on the server if you use JSF EL value binding. Also, you cannot use "this'" inside the code, because it will not point the component where Ajax request was initiated.

"onbeforedomupdate" attribute defines JavaScript code for call after Ajax response receiving and before updating DOM on a client side.

"data" attribute allows to get the additional data from the server during an Ajax call. You can use JSF EL to point the property of the managed bean and its value will be serialized in JSON format and be available on the client side. You can refer to it using the "data" variable. For example:

    ...

        <a4j:commandButton value="Update" data="#{userBean.name}" oncomplete="showTheName(data.name)" />

    ...

RichFaces allows to serialize not only primitive types into JSON format, but also complex types including arrays and collections. The beans should be serializable to be refered with "data" .

There is a number of useful functions which can be used in JavaScript:

- `rich:clientId('id')` - returns client id by short id or null if the component with the id specified hasn't been found

- `rich:element('id')` - is a shortcut for `document.getElementById(#{rich:clientId('id')})`

- `rich:component('id')` - is a shortcut for `#{rich:clientId('id')}.component`

- `rich:findComponent('id')` - returns an instance of UIComponent taking the short ID of the component as a parameter.

      ...

      <h:inputText id="myInput">

          <a4j:support event="onkeyup" reRender="outtext"/>

      </h:inputText>

      <h:outputText id="outtext" value="#{rich:findComponent('myInput').value}" />

      ...

### 5.4.6. Iteration components Ajax attributes

"ajaxKeys" attribute defines strings that are updated after an Ajax request. It provides possibility to update several child components separately without updating the whole page.

    ...

        <a4j:poll intervall="1000" action="#{repeater.action}" reRender="text">

            <table>

                <tbody>

                    <a4j:repeat value="#{bean.props}" var="detail" ajaxKeys="#{repeater.ajaxedRowsSet}">

                        <tr>

                            <td>

                                <h:outputText value="detail.someProperty" id="text"/>

                            </td>

                        </tr>

                    </a4j:repeat>

                </tbody>

            </table>

        </a4j:poll>

    ...

### 5.4.7. Other useful attributes

"status" attribute for Ajax components (such as <a4j:commandButton> , <a4j:poll> , etc.) points to an ID of <a4j:status> component. Use this attribute if you want to share <a4j:status> component between different Ajax components from different regions. The following example shows it.

    ...

        <a4j:region id="extr">

            <h:form>

                <h:outputText value="Status:" />

                <a4j:status id="commonstatus" startText="In Progress...." stopText=""/>

                <h:panelGrid columns="2">

                    <h:outputText value="Name"/>

                    <h:inputText id="name" value="#{userBean.name}">

                        <a4j:support event="onkeyup" reRender="out" />

                    </h:inputText>

                    <h:outputText value="Job"/>

                    <a4j:region  id="intr">

                        <h:inputText id="job" value="#{userBean.job}">

                            <a4j:support event="onkeyup"  reRender="out" status="commonstatus"/>

                       </h:inputText>

                    </a4j:region>

                </h:panelGrid>

                <a4j:region>

                    <h:outputText id="out" value="Name: #{userBean.name}, Job: #{userBean.job}" />

                    <br />

                    <a4j:commandButton ajaxSingle="true" value="Clean Up Form" reRender="name, job, out"  status="commonstatus">

                        <a4j:actionparam name="n" value=""  assignTo="#{userBean.name}" />

                        <a4j:actionparam name="j" value=""  assignTo="#{userBean.job}" />

                    </a4j:commandButton>

                </a4j:region>

            </h:form>

        </a4j:region>

    ...

In the example <a4j:support> and <a4j:commandButton> are defined in different regions. Values of "status" attribute for these components points to an ID of <a4j:support> .Thus, the <a4j:support> component is shared between two components from different regions.

More information could be found here .

Other useful attribute is "focus" . It points to an ID of a component where focus will be set after an Ajax request.

## 5.5. How To...

### 5.5.1. Send an Ajax request

There are different ways to send Ajax requests from your JSF page. For example you can use <a4j:commandButton> , <a4j:commandLink> , <a4j:poll> or <a4j:support> tags or any other.

All these tags hide the usual JavaScript activities that are required for an XMHTTPRequest object building and an Ajax request sending. Also, they allow you to decide which components of your JSF page are to be re-rendered as a result of the Ajax response (you can list the IDs of these components in the "reRender" attribute).

<a4j:commandButton> and <a4j:commandLink> tags are used to send an Ajax request on "onclick" JavaScript event.

<a4j:poll> tag is used to send an Ajax request periodically using a timer.

The <a4j:support> tag allows you to add Ajax functionality to standard JSF components and send Ajax request onto a chosen JavaScript event: "onkeyup" , "onmouseover" , etc.

### 5.5.2. Decide What to Send

You may describe a region on the page you wish to send to the server, in this way you can control what part of the JSF View is decoded on the server side when you send an Ajax request.

The easiest way to describe an Ajax region on your JSF page is to do nothing, because the content between the <f:view> and </f:view> tags is considered the default Ajax region.

You may define multiple Ajax regions on the JSF page (they can even be nested) by using the <a4j:region> tag.

If you wish to render the content of an Ajax response outside of the active region then the value of the "renderRegionOnly" attribute should be set to "false" ("false" is default value). Otherwise, your Ajax updates are limited to elements of the active region.

### 5.5.3. Decide What to Change

Using IDs in the "reRender" attribute to define `"AJAX zones"` for update works fine in many cases.

But you can not use this approach if your page contains, e.g. a <f:verbatim> tag and you wish to update its content on an Ajax response.

The problem with the <f:verbatim/> tag as described above is related to the value of the transientFlag of JSF components. If the value of this flag is true, the component must not participate in state saving or restoring of process.

In order to provide a solution to this kind of problems, RichFaces uses the concept of an output panel that is defined by the <a4j:outputPanel> tag. If you put a <f:verbatim> tag inside of the output panel, then the content of the <f:verbatim/> tag and content of other panel's child tags could be updated on Ajax response. There are two ways to control this:

- By setting the "ajaxRendered" attribute value to "true".

- By setting the "reRender" attribute value of an Action Component to the output panel ID.

### 5.5.4. Decide what to process

The "process" attribute allows to define the ids of components to be processed together with the component which is marked as ajaxSingle or wrapped to region.

You could make use of the "process" attribute when you need to process only two components in the different parts of view.

Imagine you need to process only two input fields but not all the view. If you wrap the first input to region or make <a4j:support> component with `ajaxSingle="true"` nested the second input will not be processed.

Here is a simple solution:

    ...

    <h:inputText value="#{bean.name}" id="name">

        <a4j:support ajaxSingle="true" process="email" event="onblur" reRender="someOut"/>

    </h:inputText>

    <h:inputTextarea value="#{bean.description}" id="desc" />

    <h:inputText value="#{bean.email}" id="email">

        <a4j:support ajaxSingle="true" process="name" event="onblur" reRender="someOut"/>

    </h:inputText>

    ...

In the example above when the input field with the `id="name"` looses focus, an AJAX request is sent. So only two input fields (with `id="name"` and additionally with `id="email"`) are processed: decoding, conversion/validation, value applying phases are executed. The input field with the `id="email"` is handled the same way on blur event.

## 5.6. Filter Configuration

RichFaces uses a filter for a correction of code received on an Ajax request. In case of a "regular" JSF request a browser makes correction independently. In case of Ajax request in order to prevent layout destruction it's needed to use a filter, because a received code could differ from a code validated by a browser and a browser doesn't make any corrections.

An example of how to set a Filter in a web.xml file of your application is placed below.

Example:

    ...

        <filter>

            <display-name>RichFaces Filter</display-name>

            <filter-name>richfaces</filter-name>

            <filter-class>org.ajax4jsf.Filter</filter-class>

        </filter>

    ...

## Note:

Fast Filter is deprecated and available only for backward compatibility with previous RichFaces versions. Fast Filter usage isn't recomended, because there is another way to use its functionality by means of Neko filter type .

In RichFaces 3.2 filter configuration becomes more flexible. It's possible to configure different filters for different sets of pages for the same application.

The possible filter types are:

- TIDY

"TIDY" filter type based on the Tidy parser. This filter is recommended for applications with complicated or non-standard markup when all necessary code corrections are made by the filter when a response comes from the server.

- NEKO

"NEKO" filter type corresponds to the former "Fast Filter" and it's based on the Neko parser. In case of using this filter code isn't strictly verified. Use this one if you are sure that your application markup is really strict for this filter. Otherwise it could cause lot's of errors and corrupt a layout as a result. This filter considerably accelerates all Ajax requests processing.

- NONE

No correction.

An example of configuration is placed below.

Example:

    ...

        <context-param>

            <param-name>org.ajax4jsf.xmlparser.ORDER</param-name>

            <param-value>NONE,NEKO,TIDY</param-value>

        </context-param>

        <context-param>

            <param-name>org.ajax4jsf.xmlparser.NONE</param-name>

            <param-value>/pages/performance\.xhtml,/pages/default.*\.xhtml</param-value>

        </context-param>

        <context-param>

            <param-name>org.ajax4jsf.xmlparser.NEKO</param-name>

            <param-value>/pages/repeat\.xhtml</param-value>

        </context-param>

        <filter>

            <display-name>RichFaces Filter</display-name>

            <filter-name>richfaces</filter-name>

            <filter-class>org.ajax4jsf.Filter</filter-class>

        </filter>

        <filter-mapping>

            <filter-name>richfaces</filter-name>

            <servlet-name>Faces Servlet</servlet-name>

            <dispatcher>FORWARD</dispatcher>

            <dispatcher>REQUEST</dispatcher>

            <dispatcher>INCLUDE</dispatcher>

        </filter-mapping>

    ...

The example shows that `ORDER` parameter defines the order in which particular filter types are used for pages code correction.

First of all "NONE" type is specified for the filter. Then two different sets of pages are defined for which two filter types (NONE and NEKO) are used correspondingly. If a page relates to the first set that is defined in the following way:

    <param-value>/pages/performance\.xhtml,/pages/default.*\.xhtml</param-value>,

it's not corrected, because filter type for this page is defined as "NONE". If a page is not from the first set, then "NEKO" type is set.

If a page relates to the second set that is defined in the following way:

    <param-value>/pages/repeat\.xhtml</param-value>,

then "NEKO" filter type is used for correction. If it's not related to the second set, "TIDY" type is set for the filter ("TIDY" filter type is used for code correction).

## 5.7. Scripts and Styles Load Strategy

Before the version 3.1.3, RichFaces loaded styles and script on demand. I.e. files are loaded only if they are required on a particular page. Since RichFaces 3.1.3, it's possible to manage how the RichFaces script and style files are loaded to application.

org.richfaces.LoadScriptStrategy

The following declaration in your web.xml allows loading the integrated script files.

    ...

        <context-param>

              <param-name>org.richfaces.LoadScriptStrategy</param-name>

              <param-value>ALL</param-value>

        </context-param>

    ...

If you do not declare the `org.richfaces.LoadScriptStrategy` in the web.xml, it equals to:

    ...

        <context-param>

            <param-name>org.richfaces.LoadScriptStrategy</param-name>

            <param-value>DEFAULT</param-value>

        </context-param>

    ...

The third possible value is "NONE". You have no a special reason to use it unless you obtain the newest (or modified) version of the script and want to include it manually in a page header.

## Note:

If you use ALL value of Scripts Load Strategy, the JavaScript files compression turns off!

org.richfaces.LoadStyleStrategy

The following declaration allows to load only one integrated style sheet file.

    ...

        <context-param>

              <param-name>org.richfaces.LoadStyleStrategy</param-name>

              <param-value>ALL</param-value>

        </context-param>

    ...

The integrated style sheet contains style for all shipped components. The skinnability feature still works.

The "DEFAULT" value is a classical on-demand variant.

The "NONE" stops loading the styles at all. The earlier introduced plain skin resets all color and font parameters to null. The "NONE" value for `org.richfaces.LoadStyleStrategy` means that predefined styles for RichFaces are not used.

For more information see RichFaces User Forum .

## 5.8. Request Errors and Session Expiration Handling

RichFaces allows to redefine standard handlers responsible for processing of different exceptional situations. It helps to define own JavaScript, which is executed when these situations occur.

Add the following code to web.xml:

    <context-param>

        <param-name>org.ajax4jsf.handleViewExpiredOnClient</param-name>

        <param-value>true</param-value>

    </context-param>

### 5.8.1. Request Errors Handling

To execute your own code on the client in case of an error during Ajax request, it's necessary to redefine the standard `"A4J.AJAX.onError"` method:

     A4J.AJAX.onError = function(req,status,message){

        window.alert("Custom onError handler "+message);

    }

The function defined this way accepts as parameters:

- `req` - a params string of a request that calls an error

- `status` - the number of an error returned by the server

- `message` - a default message for the given error

Thus, it's possible to create your own handler that is called on timeouts, inner server errors, and etc.

### 5.8.2. Session Expired Handling

It's possible to redefine also the "onExpired" framework method that is called on the "Session Expiration" event.

Example:

    A4J.AJAX.onExpired = function(loc,expiredMsg){

        if(window.confirm("Custom onExpired handler "+expiredMsg+" for a location: "+loc)){

          return loc;

        } else {

         return false;

        }

    }

Here the function receives in params:

- `loc` - URL of the current page (on demand can be updated)

- `expiredMsg` - a default message on "Session Expiration" event.

## 5.9. Skinnability

### 5.9.1. Why Skinnability

If you have a look at a CSS file in an enterprise application, for example, the one you're working on now, you'll see how often the same color is noted in it. Standard CSS has no way to define a particular color abstractly for defining as a panel header color, a background color of an active pop-up menu item, a separator color, etc. To define common interface styles, you have to copy the same values over and over again and the more interface elements you have the more copy-and-paste activity that needs to be performed.

Hence, if you want to change the application palette, you have to change all interrelating values, otherwise your interface can appear a bit clumsy. The chances of such an interface coming about is very high, as CSS editing usually becomes the duty of a general developer who doesn't necessarily have much knowledge of user interface design.

Moreover, if a customer wishes to have an interface look-and-feel that can be adjusted on-the-fly by an end user, your work is multiplied, as you have to deal with several CSS files variants, each of which contains the same values repeated numerous times.

These problems can be solved with the skinnability system built into the RichFaces project and realized fully in RichFaces. Every named skin has some skin-parameters for the definition of a palette and the other parameters of the user interface. By changing just a few parameters, you can alter the appearance of dozens of components in an application in a synchronized fashion without messing up user interface consistency.

The skinnability feature can't completely replace standard CSS and certainly doesn't eliminate its usage. Skinnability is a high-level extension of standard CSS, which can be used together with regular CSS declarations. You can also refer to skin parameters in CSS via JSF Expression Language. You have the complete ability to synchronize the appearance of all the elements in your pages.

### 5.9.2. Using Skinnability

RichFaces skinnability is designed for mixed usage with:

- Skin parameters defined in the RichFaces framework

- Predefined CSS classes for components

- User style classes

The color scheme of the component can be applied to its elements using any of three style classes:

- A default style class inserted into the framework

  This contains style parameters linked to some constants from a skin. It is defined for every component and specifies a default representation level. Thus, an application interface could be modified by changing the values of skin parameters.

- A style class of skin extension

  This class name is defined for every component element and inserted into the framework to allow defining a class with the same name into its CSS files. Hence, the appearance of all components that use this class is extended.

- User style class

  It's possible to use one of the styleClass parameters for component elements and define your own class in it. As a result, the appearance of one particular component is changed according to a CSS style parameter specified in the class.

### 5.9.3. Example

Here is a simple panel component:

Example:

                    <rich:panel> ... </rich:panel>

The code generates a panel component on a page, which consists of two elements: a wrapper <div> element and a <div> element for the panel body with the particular style properties. The wrapper <div> element looks like:

Example:

                    <div class="dr-pnl rich-panel"> ... </div>

dr-pnl is a CSS class specified in the framework via skin parameters:

- background-color is defined with generalBackgroundColor

- border-color is defined with panelBorderColor

It's possible to change all colors for all panels on all pages by changing these skin parameters.

However, if a <rich:panel> class is specified somewhere on the page, its parameters are also acquired by all panels on this page.

A developer may also change the style properties for a particular panel. The following definition:

Example:

                    <rich:panel styleClass="customClass"> ...

                    </rich:panel>

Could add some style properties from customClass to one particular panel, as a result we get three styles:

Example:

                    <div class="dr_pnl rich-panel customClass"> ...

                    </div>

### 5.9.4. Skin Parameters Tables in RichFaces

RichFaces provides eight predefined skin parameters (skins) at the simplest level of common customization:

- DEFAULT

- plain

- emeraldTown

- blueSky

- wine

- japanCherry

- ruby

- classic

- deepMarine

To plug one in, it's necessary to specify a skin name in the `org.richfaces.SKIN` context-param.

Here is an example of a table with values for one of the main skins, "blueSky" .

Table 5.1. Colors

Parameter name | Default value
--- | ---
headerBackgroundColor | #BED6F8
headerGradientColor | #F2F7FF
headTextColor | #000000

buttonSizeFont | 11px
buttonFamilyFont | Arial, Verdana, sans-serif
tableBackgroundColor | #FFFFFF
tableFooterBackgroundColor | #cccccc
tableSubfooterBackgroundColor | #f1f1f1
tableBorderColor | #C0C0C0

Skin "plain" was added from 3.0.2 version. It doesn't have any parameters. It's necessary for embedding RichFaces components into existing projecst which have its own styles.

To get detailed information on particular parameter possibilities, see the chapter where each component has skin parameters described corresponding to its elements.

### 5.9.5. Creating and Using Your Own Skin File

In order to create your own skin file, do the following:

- Create a file and define in it skin constants which are used by style classes (see section "Skin Parameters Tables in RichFaces" ). The name of skin file should correspond to the following format: `<name>.skin.properties` . As an example of such file you can see RichFaces predefined skin parameters (skins): blueSky, classic, deepMarine, etc. These files are located in the `richfaces-impl-xxxxx.jar` inside the /META-INF/skins folder.

- Add a skin definition `<contex-param>` to the web.xml of your application. An example is placed below:

  Example:

      ...

          <context-param>

              <param-name>org.richfaces.SKIN</param-name>

              <param-value>name</param-value>

          </context-param>

      ...

- Put your `<name>.skin.properties` file in one of the following classpath elements: META-INF/skins/ or classpath folder (e.g. WEB-INF/classes).

### 5.9.6. Built-in skinnability in RichFaces

RichFaces gives an opportunity to incorporate skinnability into UI design. With this framework you can easily use named skin parameters in properties files to control the appearance of the skins that are applied consistently to a whole set of components. You can look at examples of predefined skins at:

http://livedemo.exadel.com/richfaces-demo/

You may simply control the look-and-feel of your application by using the skinnability service of the RichFaces framework. With the means of this service you can define the same style for rendering standard JSF components and custom JSF components built with the help of RichFaces.

To find out more on skinnability possibilities, follow these steps:

- Create a custom render kit and register it in the faces-config.xml like this:

      <render-kit>

              <render-kit-id>NEW_SKIN</render-kit-id>

              <render-kit-class>

                  org.ajax4jsf.framework.renderer.ChameleonRenderKitImpl

              </render-kit-class>

      </render-kit>

- Then you need to create and register custom renderers for the component based on the look-and-feel predefined variables:

      <renderer>

              <component-family>javax.faces.Command</component-family>

              <renderer-type>javax.faces.Link</renderer-type>

              <renderer-class>

                 newskin.HtmlCommandLinkRenderer

              </renderer-class>

      </renderer>

- Finally, you need to place a properties file with skin parameters into the class path root. There are two requirements for the properties file:

  - The file must be named `<skinName>.skin.properties` , in this case, it would be called `newskin.skin.properties` .

  - The first line in this file should be `render.kit=<render-kit-id>` in this case, it would be called `render.kit=NEW_SKIN` .

Extra information on custom renderers creation can be found at:

http://java.sun.com/javaee/javaserverfaces/reference/docs/index.html

### 5.9.7. Standard controls skinning

The feature is designed to unify the look and feel of standard HTML element and RichFaces components. Skinning can be applied to all controls on a page basing on elements' name and attribute type (where applicable). Also this feature provides a set of CSS styles so that skinning can be applied assigning rich-* classes to particular elements or to container of elements that nests controls.

Standard controls skinning feature provides 2 levels of skinning - standard and extended, while skinning is based on detecting browser user agent. If user agent is not detected, Advanced level is used.

- Standard provides customization only basic style properties.

  To the following browsers Basic level of skinning is applied:

  - Internet Explorer 6

  - Internet Explorer 7 in BackCompat mode (see document.compatMode property in MSDN )

  - Opera

  - Safari

- Extended extends basic level introducing broader number of style properties and is applied to browsers with rich visual styling capability of controls

  The following browsers support Advanced level of skinning:

  - Mozilla Firefox

  - Internet Explorer 7 in Standards-compliant mode (CSS1Compat mode)

These are the elements that affected by skinning:

- input

- select

- textarea

- keygen

- isindex

- legend

- fieldset

- hr

- a (together with a:hover, a:visited "pseudo"-elements)

Skinning can be initialized in two ways:

- adding `org.richfaces.CONTROL_SKINNING` parmeter to web.xml. Values: "enable" and "disable". This way implies that skinning style classes are applied to elements by element name and type attribute (where applicable). No additional steps required from an application developer. Please find below the table that contains the list of element to which skinning a applicable.

- adding `org.richfaces.CONTROL_SKINNING_CLASSES` parameter to web.xml file. Possible values "enable" and "disable". Implementation of this method implies the provision of several style classes for different types of elements. The style classes have predefined names. Application developer should manually assign classes to controls that needs skinning or assign class to an element that contains controls.

By setting `org.richfaces.CONTROL_SKINNING_CLASSES` to "enable" you are provided with style classes applicable to:

- Basic elements nested inside element having rich-container class, e.g.:

  Example:

      ...

      .rich-container select {

         //class content

      }

      ...

- Elements that have class name corresponding to one of the basic elements name/type mapped by the following scheme `rich-<elementName>[-<elementType>]` . See the example:

  Example:

      ...

      .rich-select {

        //class content

      }

      .rich-input-text {

        //class content

      }

      ...

  ## Note:

  a elements have classes based on "link" and pseudo class name, e.g.: rich-link, rich-link-hover, rich-link-visited

Additionally, the predefined rich CSS classes that we provide can be used not only as classes for basic HTML elements but also as classes for creation of complex elements .

There is a snippet with some of them for example:

    ...

    <u:selector name=".rich-box-bgcolor-header">

        <u:style name="background-color" skin="headerBackgroundColor" />

    </u:selector>

    <u:selector name=".rich-box-bgcolor-general">

       <u:style name="background-color" skin="generalBackgroundColor" />

    </u:selector>

    ...

    //gradient elements

    ...

    <u:selector name=".rich-gradient-menu">

        <u:style name="background-image">

            <f:resource f:key="org.richfaces.renderkit.html.gradientimages.MenuGradientImage"/>

        </u:style>

        <u:style name="background-repeat" value="repeat-x" />

    </u:selector>

    <u:selector name=".rich-gradient-tab">

        <u:style name="background-image">

            <f:resource f:key="org.richfaces.renderkit.html.gradientimages.TabGradientImage"/>

        </u:style>

        <u:style name="background-repeat" value="repeat-x" />

    </u:selector>

    ...

To get a better idea of standard component skinning we recommend to explore CSS files located in ui/core/src/main/resources/org/richfaces/ folder of RichFaces svn.

### 5.9.8. Client-side script for extended skinning support

As it was mentioned earlier in the guide, extended skinning of standard HTML controls is applied automatically: the browser type is detected and if a browser doesn't fully support extended skinning feature, only basic skinning is applied.

However, if a develop doesn't want to the rich components and standard HTML controls to be skinned automatically and perform the skinnability implementation himself, he might encounter with a problem, i.e. standard HTML controls in such browsers as Opera and Safari are affected by standard controls skinning featured. ( Here you can get more details on how to disable skinnability.)

In brief, to disable the skinnability mechanism of RichFaces you need to set the "org.richfaces.LoadStyleStrategy" parameter to "NONE" in web.xml.

    ...

    <context-param>

        <param-name>org.richfaces.LoadStyleStrategy</param-name>

        <param-value>NONE</param-value>

    </context-param>

    ...

Additionally, you should include the style sheets that perform skinning of the rich component and standard HTML controls.

In order to resolve the problem with extended skinning in Opera and Safari a client script (skinning.js) is added to the RichFaces library. The script detects the browser type and enables extended skinning only for those browsers that fully support it.

The script can be activated by inserting this JavaScript code to the page:

    <script type="text/javascript">

    window.RICH_FACES_EXTENDED_SKINNING_ON = true;

    </script>

You also need to specify "media" attribute in the <link> tag which includes the "extended_both.xcss" style sheet with "rich-extended-skinning".

This is how you can include the style sheets to the page, in case automatic skinnability implementation is disabled.

## Note

Now necessary to use resources prefix `a4j/versionXXX` instead of `a4j_versionXXX`. Base64 encoder changed to use '`!`' instead of '`.`'.

### 5.9.9. XCSS file format

XCSS files are the core of RichFaces components skinnability.

XCSS is an XML formatted CSS that adds extra functionality to the skinning process

XCSS extends skinning possibilities by parsing the XCSS file that contains all look-and-feel parameters of a particular component into a standard CSS file that a web browser can recognize.

XCSS file contains CSS properties and skin parameters mappings. Mapping of a CSS selector to a skin parameter is performed using < u:selector > and < u:style> XML tags that form the mapping structure. Please study the example below.

    ...

        <u:selector name=".rich-component-name">

            <u:style name="background-color" skin="additionalBackgroundColor" />

            <u:style name="border-color" skin="tableBorderColor" />

            <u:style name="border-width" skin="tableBorderWidth" />

            <u:style name="border-style" value="solid" />

        </u:selector>

    ...

During processing the code in the shown example will be parsed into a standard CSS format.

    ...

    .rich-component-name {

    background-color: additionalBackgroundColor; /*the value of the constant defined by your skin*/

    border-color: tableBorderColor; /*the value of the constant defined by your skin*/

    border-width: tableBorderWidth /*the value of the constant defined by your skin*/

    border-style: solid;

    }

    ...

The "name" attribute of <u:selector> tag defines the CSS selector, while "name" attribute of the <u:style> tag defines what skin constant is mapped to a CSS property. The "value" attribute of the <u:style> tag can also be used to assign a value to a CSS property.

CSS selectors with identical skinning properties can be set as a comma separated list.

    ...

    <u:selector name=".rich-ordering-control-disabled, .rich-ordering-control-top, .rich-ordering-control-bottom, .rich-ordering-control-up, .rich-ordering-control-down">

            <u:style name="border-color" skin="tableBorderColor" />

    </u:selector>

    ...

### 5.9.10. Plug-n-Skin

Plug-n-Skin is a feature that gives a developer an opportunity to easily create, customize and plug into a project a custom skin. The skin can be created basing on parameters of some predefined RichFaces skin.

The feature also provides an option to unify the appearance of rich controls with standard HTML elements.

In order to create your own skin using Plug-n-Skin feature, you can follow these step by step instructions.

First of all, you need to create a template for the new skin. Creation of the template can be performed using Maven build and deployment tool. More information on how to configure Maven for RichFaces here . You can copy and paste these Maven instructions to command line and execute them.

    ...

    mvn archetype:create

    -DarchetypeGroupId=org.richfaces.cdk

    -DarchetypeArtifactId=maven-archetype-plug-n-skin

    -DarchetypeVersion=RF-VERSION

    -DartifactId=ARTIFACT-ID

    -DgroupId=GROUP-ID

    -Dversion=VERSION

    ...

Primary keys for the command:

- `DarchetypeVersion` indicates the RichFaces version. For example, `"3.2.2.GA"`

- `DartifactId` artifact id of the project

- `DgroupId` group id of the project

- `Dversion` the version of the project you create, by default it is `"1.0.-SNAPSHOT"`

After this operation, a folder with the name of your `"ARTIFACT-ID"` appears. The folder contains a template of Maven project.

Next steps will guide you though creating of the skin itself.

In the root folder of Maven project (the one that contains "pom.xml" file) you should run the following command in the command line:

    ...

    mvn cdk:add-skin -Dname=SKIN-NAME -Dpackage=SKIN-PACKAGE

    ...

Primary keys for the command:

- `Dname` defines the name of the new skin

- `Dpackage` base package of the skin. By default "groupId" of the project is used.

Additional optional keys for the command:

- `DbaseSkin` defines the name of the base skin.

- `DcreateExt` if set to "true", extended CSS classes are added. For more information, please, see "Standard controls skinning"

As a result of the performed operations the following files and folders are created:

- BaseImage.java - the base class to store images. Location: "\src\main\java\SKIN-PACKAGE\SKIN-NAME\images\"

- BaseImageTest.java - a test version of a class that stores images. Location: "\src\test\java\SKIN-PACKAGE\SKIN-NAME\images\"

- XCSS files - XCSS files define the new look of RichFaces components affected by the new skin. Location: "\src\main\resources\SKIN-PACKAGE\SKIN-NAME\css\"

- SKIN-NAME.properties - a XCSS file that contains properties of the new skin. Location: "\src\main\resources\SKIN-PACKAGE\SKIN-NAME\css\"

  The following properties are used to configure the SKIN-NAME.properties file:

  - baseSkin – the name of the base skin to be used as basis. The look of the skin you define will be affected by new style properties.

  - generalStyleSheet - a path to the style sheet (SKIN-NAME.xcss) that imports style sheets of the components to be affected by the new skin.

  - extendedStyleSheet - a path to a style sheet that is used to unify the appearance of RichFaces components and standard HTML controls. For additional information please read "Standard controls skinning" chapter.

  - gradientType is a predefined property to set the type of gradient applied to the new skin. Possible values are glass, plastic, plain. More information on gradient implementation you can find further in this chapter.

- SKIN-NAME.xcss - a XCSS file that imports XCSS files of the components to be affected by the new skin. Location: "src\main\resources\META-INF\skins "

- XCSS files If the command is executed with the "DcreateExt" key set to "true", the XCSS (extended_classes.xcss and extended.xcss) files that define style for standard controls will be created. Location: "\src\main\resources\SKIN-PACKAGE\SKIN-NAME\css\".

- SKIN-NAME-ext.xcss / If the command is executed with the "DcreateExt" key set to "true", the configuration SKIN-NAME-ext.xcss file that imports XCSS file defining styles for the standard controls will be created. Location: "src\main\resources\META-INF\skins ".

- SKIN-NAME-resources.xml - the file contains the description of all listed above files. Location: "src\main\config\resources ".

Now you can start editing the XCSS files located in "\src\main\resources\SKIN-PACKAGE\SKIN-NAME\css\". New style properties can be assigned to the selectors (the selectors listed in the XCSS files) in two ways, which are both valid, and it'up to the developer what way to choose.

- Applying a standard CSS coding approach, i.e. you can add css properties to the given selectors are you normally do while doing CSS coding. The only thing, you have to keep in mind is that the selectors must be inside `<f:verbatim> <![CDATA[ ...]]> </f:verbatim>` tags.

  For example

      ...

      .rich-calendar-cell {

      background: #537df8;

      }

      ...

- Using XCSS coding approach, the same way as XCSS files are normally formed in RichFaces. The XCSS tags have to be placed outside `<f:verbatim> <![CDATA[ ...]]> </f:verbatim>` tags.

                  ...

      <u:selector name=".rich-calendar-cell">

          <u:style name="border-bottom-color" skin="panelBorderColor"/>

          <u:style name="border-right-color" skin="panelBorderColor"/>

          <u:style name="background-color" skin="tableBackgroundColor"/>

          <u:style name="font-size" skin="generalSizeFont"/>

          <u:style name="font-family" skin="generalFamilyFont"/>

      </u:selector>

      ...

Having performed described above steps and edited the XCSS files you can proceed to building the new skin and to plugging it into the project. Building the new skin can be done by executing the given below command in the command line in the root folder of you skin project (the one that contains pom.xml file).

    ...

    mvn clean install

    ...

In addition Plug-n-Skin has a number of predefined gradients that you can also use to make your application look nicer. The given below code snippet shows how a gradient can be used

    ...

    <u:selector name=".rich-combobox-item-selected">

        <u:style name="border-width" value="1px" />

        <u:style name="border-style" value="solid" />

        <u:style name="border-color" skin="newBorder" />

        <u:style name="background-position" value="0% 50%" />

        <u:style name="background-image">

            <f:resource f:key="org.richfaces.renderkit.html.CustomizeableGradient">

                <f:attribute name="valign" value="middle" />

                <f:attribute name="gradientHeight" value="17px" />

                <f:attribute name="baseColor" skin="headerBackgroundColor" />

             </f:resource>

        </u:style>

    </u:selector>

    ...

So, as you can see, the background-image CSS property is defined with `<f:resource f:key="org.richfaces.renderkit.html.CustomizeableGradient">` that sets the gradient. While the gradient type can be specified in the SKIN-NAME.properties file with gradientType property. The gradientType property can be set to one of the possible values glass, plastic, plain. The gradient in it's turn can be can be adjusted using baseColor, gradientColor, gradientHeight, valign attributes. Their usage is shown in the snippet above.

Now, you can use your newly-created and customized skin in your project by adding your new skin parameters to web.xml file and placing the jar file with your skin ( the jar file is located in "target" folder of your skin project) to "\WebContent\WEB-INF\lib\".

    ...

    <context-param>

        <param-name>org.ajax4jsf.SKIN</param-name>

        <param-value>SKIN-NAME</param-value>

    </context-param>

    ...

#### 5.9.10.1. Details of Usage

This section will cover some practical aspects of Plug-n-Skin implementation. It's assumed that you have read the section of the guide that tells how the new skin using Plug-n-Skin prototype can be created.

Above all, we need to create a new skin, in order to do that we just have to follow the steps described in the previous section.

This command will be used to create a template of the new skin project.

    mvn archetype:create

    -DarchetypeGroupId=org.richfaces.cdk

    -DarchetypeArtifactId=maven-archetype-plug-n-skin

    -DarchetypeVersion=3.2.2.GA

    -DartifactId=P-n-S

    -DgroupId=GROUPID

    -Dversion=1.0.-SNAPSHOT

Now you can browse the "P-n-S" folder to view what files and folders were created there.

Next, we will use Maven to add all needed files to the skin project. This will done by the following command:

    mvn cdk:add-skin -DbaseSkin=blueSky  -DcreateExt=true -Dname=PlugnSkinDemo -Dpackage=SKINPACKAGE

As you remember from the previous section "-DbaseSkin" key defines what RichFaces built-in skin to be used as a base one, "-DcreateExt=true" determines that the new skin will come with XCSS files that unify the look of the rich components with standard HTML controls.

So, now the files and folder with all needed resources are created and redefining/editing the new skin can be started.

Now we can start editing XCSS files of the rich components. In order to see how the Plug-n-Skin feature works we will change some style attributes of <rich:calendar> and some basic HTML controls to see how they are affected by standard controls skinning.

Thus, it will be demonstrated how to:

- Recolor the current day's cell background of the <rich:calendar> to see how the new skin created with the help of Plug-n-Skin feature affects the style of the component;

- Recolor a standard HTML submit button;

In oder to edit the style properties of <rich:calendar> you need to open the "calendar.xcss" file located in "P-n-S\src\main\resources\skinpackage\plugnskindemo\css\". Once, you have opened the file, please find ".rich-calendar-today" selector and amend it as follows: `background-color: #075ad1;`. The current day's background color can be considered recolored.

Now we will see how font style of a standard HTML submit button can be changed. Please, open "extended.xcss" file located in "P-n-S\src\main\resources\skinpackage\plugnskindemo\css\" and put in `font-weight: bold;` inside the curly braces of these coma separated selectors `button[type="button"], button[type="reset"], button[type="submit"], input[type="reset"], input[type="submit"], input[type="button"]`. So, the CSS code should look like this.

    button[type=&quot;button&quot;], button[type=&quot;reset&quot;], button[type=&quot;submit&quot;], input[type=&quot;reset&quot;], input[type=&quot;submit&quot;], input[type=&quot;button&quot;] {

    font-weight: bold;

    }

All the changes that were planned to be preformed are done and now you can proceed to building the new PlugnSkinDemo skin and import it into the project. As you read in the previous section, the skin should be built in the "P-n-S" folder of the skin project be executing `mvn clean install` command. This procedure results in creating a "target" folder that contains a .jar file with a compiled new skin, it our case the file is named "P-n-S-1.0.-SNAPSHOT.jar". The next step is to import the new PlugnSkinDemo skin into the project.

What you need to do, in order to have the new skin imported to the project is to

- Copy the "P-n-S-1.0.-SNAPSHOT.jar" file to the "\WebContent\WEB-INF\lib\" folder.

- Add the new skin's name to the "web.xml" file. It is done like this

       <context-param>

        <param-name>org.ajax4jsf.SKIN</param-name>

        <param-value>PlugnSkinDemo</param-value>

       </context-param>

Please, do not forget that standard controls skinning has to be enabled in the "web.xml" file, which can be done by adding the following code to the "web.xml" file:

     <context-param>

      <param-name>org.richfaces.CONTROL_SKINNING</param-name>

      <param-value>enable</param-value>

     </context-param>

The result of both action is displayed on the figure below.

Figure 5.5. Plug-n-Skin feature in action.

## 5.10. State Manager API

JSF has an advanced navigation mechanism that allows you to define navigation from view to view. Navigation happens in a Web Application when a user tries to switch from one page to another page either by clicking a button, a hyperlink, or another command component. But there is no switch mechanism between some logical states of the same view. For example in Login/Register dialog an existing user signs in with his user name and password, but if a new user registers an additional field "Confirm" is displayed, buttons labels and methods are changed when the user clicks "To register" link:

Figure 5.6. Login Dialog

Figure 5.7. Register Dialog

RichFaces State API allows easily to define some set of states for the pages and any properties for this states.

Actually States is a map where the entry key is a name of the State and the value is a State map. Particular State map has entries with some names as keys and any objects as values that are used after the state activation. Thus, in the State map you could define any values, method bindings, or just some simple state variables (constants) which have different values for every State.

Figure 5.8. RichFaces State API

One of the most convenience features of the RichFaces State API is a navigation between states. The RichFaces State API implements states change as the standard JSF navigation. Action component just returns outcome and the RichFaces State API extension for the JSF navigation handler checks whether this outcome is registered as a state change outcome or not. If the state change outcome is found the corresponding state is activated. Otherwise the standard navigation handling is called.

In order to use RichFaces State API you should follow the next steps:

- Register State Manager EL resolver and navigation handler in the faces-config.xml:

      ...

      <application>

          <navigation-handler>org.richfaces.ui.application.StateNavigationHandler</navigation-handler>

          <el-resolver>org.richfaces.el.StateELResolver</el-resolver>

      </application>

      ...

- Register an additional application factory in the faces-config.xml:

      ...

      <factory>

          <application-factory>org.richfaces.ui.application.StateApplicationFactory</application-factory>

      </factory>

      ...

- Register two managed beans in the faces-config.xml:

      ...

      <managed-bean>

          <managed-bean-name>state</managed-bean-name>

          <managed-bean-class>org.richfaces.ui.model.States</managed-bean-class>

          <managed-bean-scope>request</managed-bean-scope>

          <managed-property>

              <property-name>states</property-name>

              <property-class>org.richfaces.ui.model.States</property-class>

              <value>#{config.states}</value>

          </managed-property>

      </managed-bean>

      <managed-bean>

          <managed-bean-name>config</managed-bean-name>

          <managed-bean-class>org.richfaces.demo.stateApi.Config</managed-bean-class>

          <managed-bean-scope>none</managed-bean-scope>

      </managed-bean>

      ...

  One bean ("config") defines and stores states as it is shown in the following example:

      ...

      public class Config {

          /**

           * @return States

           */

          public States getStates() {

              FacesContext facesContext = FacesContext.getCurrentInstance();

              States states = new States();

              // Registering new User State definition

              states.setCurrentState("register"); // Name of the new state

              // Text labels, properties and Labels for controls in "register" state

              states.put("showConfirm", Boolean.TRUE); // confirm field rendering

              states.put("link", "(To login)"); // Switch State link label

              states.put("okBtn", "Register"); // Login/Register button label

              states.put("stateTitle", "Register New User"); // Panel title

              ExpressionFactory expressionFactory = facesContext.getApplication()

                      .getExpressionFactory();

              // Define "registerbean" available under "bean" EL binding on the page

              ValueExpression beanExpression = expressionFactory

                      .createValueExpression(facesContext.getELContext(),

                              "#{registerbean}", Bean.class);

              states.put("bean", beanExpression);

              // Define "registeraction" available under "action" EL binding on the

              // page

              beanExpression = expressionFactory.createValueExpression(facesContext

                      .getELContext(), "#{registeraction}", RegisterAction.class);

              states.put("action", beanExpression);

              // Define method expression inside registeraction binding for this state

              MethodExpression methodExpression = expressionFactory.createMethodExpression(

                      facesContext.getELContext(), "#{registeraction.ok}",

                      String.class, new Class[] {});

              states.put("ok", methodExpression);

              // Outcome for switching to login state definition

              states.setNavigation("switch", "login");

              // Login Existent User State analogous definition

              states.setCurrentState("login");

              states.put("showConfirm", Boolean.FALSE);

              states.put("link", "(To register)");

              states.put("okBtn", "Login");

              states.put("stateTitle", "Login Existing User");

              beanExpression = expressionFactory.createValueExpression(facesContext

                      .getELContext(), "#{loginbean}", Bean.class);

              states.put("bean", beanExpression);

              beanExpression = expressionFactory.createValueExpression(facesContext

                      .getELContext(), "#{loginaction}", LoginAction.class);

              states.put("action", beanExpression);

              methodExpression = expressionFactory.createMethodExpression(

                      facesContext.getELContext(), "#{loginaction.ok}",

                      String.class, new Class[] {});

              states.put("ok", methodExpression);

              states.setNavigation("switch", "register");

              return states;

          }

      }

      ...

  The other bean ("state") with the type `org.richfaces.ui.model.States` has the "states" managed property that is bound to the "config" bean which defines states.

- Use state bindings on the page. See the following example:

      ...

      <h:panelGrid columns="3">

          <h:outputText value="username" />

          <h:inputText value="#{state.bean.name}" id="name" required="true" />

          <h:outputText value="password" />

          <h:inputSecret value="#{state.bean.password}" id="password" required="true" />

          <h:outputText value="confirm" rendered="#{state.showConfirm}" />

          <h:inputSecret value="#{state.bean.confirmPassword}" rendered="#{state.showConfirm}" id="confirm" required="true" />

      </h:panelGrid>

      <a4j:commandButton actionListener="#{state.action.listener}" action="#{state.ok}" value="#{state.okBtn}" id="action"/>

      ...

## Chapter 6. The RichFaces Components

The library encompasses ready-made components built based on the Rich Faces CDK .

## 6.1. < a4j:ajaxListener >

### 6.1.1. Description

The <a4j:ajaxListener> component is the same one as <f:actionListener> or <f:valueChangeListener> , but for an Ajax container.

Table 6.1. a4j : ajaxListener attributes

Attribute Name | Description
--- | ---
type | Fully qualified Java class name of an AjaxListener to be created and registered.

Table 6.2. Component identification parameters

Name | Value
--- | ---
listener-class | org.ajax4jsf.framework.ajax.AjaxListener
event-class | org.ajax4jsf.framework.ajax.AjaxEvent
tag-class | org.ajax4jsf.taglib.html.jsp.AjaxListenerTag

### 6.1.2. Creating on a page

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <a4j:ajaxListener type="demo.Bean"/>

    ...

### 6.1.3. Creating the Component Dynamically Using Java

Example:

    package demo;

    public class ImplBean implements import org.ajax4jsf.component.html.AjaxListener{

        ...

    }

    import demo.ImplBean;

    ...

    ImplBean myListener = new ImplBean();

    ...

### 6.1.4. Key attributes and ways of usage

Additional to the listeners provided by JSF specification, RichFaces add one more: ajax Listener ( <a4j:ajaxListener> ). Ajax Listener is invoked before the Render Response phase. Instead of <f:actionListener> of <f:valueChangeListener> which are not invoked when Validation of Update Model phases failed, ajax Listener is guarantied to be invoked for each Ajax response. Thus, it is a good place for update the list of re-rendered components, for example. Ajax Listener is not invoked for non-Ajax request and when RichFaces works in "Ajax Request generates Non-Ajax Response" mode. Therefore, ajax Listener invocation is a good indicator that Ajax response is going to be processed. Attribute "type" described in the following chapter. It defines the fully qualified Java class name for listener. This class implements `org.ajax4jsf.framework.ajax.ajaxListener` interface. You can access to the source of the event (Ajax component) using `event.getSource()` call.

Example:

    ...

        <a4j:commandLink id="cLink" value="Click it To Send Ajax Request">

            <a4j:ajaxListener type="demo.Bean"/>

        </a4j:commandLink>

    ...

Example:

    package demo;

    import org.ajax4jsf.framework.ajax.AjaxEvent;

    public class Bean implements org.ajax4jsf.framework.ajax.AjaxListener{

    ...

        public void processAjax(AjaxEvent arg0){

            //Custom Developer Code

        }

    ...

    }

### 6.1.5. Relevant resources links

Some additional information about usage of component can be found here.

More information about <f:valueChangeListener> can be found here.

## 6.2. < a4j:keepAlive >

### 6.2.1. Description

The <a4j:keepAlive> tag allows to keep a state of a bean between requests.

Table 6.3. a4j : keepAlive attributes

Attribute Name | Description
--- | ---
ajaxOnly | if true, bean value restored in ajax requests only.
beanName | name of bean for EL-expressions.

Table 6.4. Tag identification parameters

Name | Value
--- | ---
component-type | org.ajax4jsf.components.KeepAlive
component-family | org.ajax4jsf.components.AjaxKeepAlive
component-class | org.ajax4jsf.components.AjaxKeepAlive

### 6.2.2. Using the tag on a Page

To create the simplest variant on a page use the following syntax:

Example:

    <a4j:keepAlive beanName = "testBean"/>

Note, that to be put into the request scope the pointed bean should be registered inside faces-config.xml file and marked with org.ajax4jsf.model.KeepAlive annotation.

### 6.2.3. Key attributes and ways of usage

If a managed bean is declared with request scope in the configuration file with the help of <managed-bean-scope> tag then the life-time of this bean instance is valid only for the current request. Any attempts to make a reference to the bean instance after the request end will throw in Illegal Argument Exception by the server. To avoid these kinds of Exception, component <a4j:keepAlive> is used to maintain the state of the whole bean object among subsequent request.

Example:

    <a4j:keepAlive beanName = "#{myClass.testBean}"/>

The "beanName" attribute defines the request scope bean name you'd like to re-use. Note that this attribute must point to a legal JSF EL expression which resolves to a managed mean instance. For example for the above code the class definition may look like this one:

    class MyClass{

        ...

        private TestBean testBean;

        // Getters and Setters for testBean.

        ...

    }

The "ajaxOnly" attribute declares whether the value of the bean should be available during a non-Ajax request. If the value of this attribute is "true" a request scope bean keeps the same value during Ajax requests from the given page. If a non-Ajax request is sent from this page the bean is re-created as a regular request scope bean.

Some additional information about usage of component can be found here.

## 6.3. < a4j:actionparam >

### 6.3.1. Description

The <a4j:actionparam> component combines the functionality of both JSF components: <f:param> and <f:actionListener> .

More information about <f:param> and <f:actionListener> can be found here.

Table 6.5. a4j : actionparam attributes

Attribute Name | Description
--- | ---
actionListener | A method binding that refers to a method with this signature: void methodName(ActionEvent)
assignTo | EL expression for updatable bean property. This property will be updated if the parent command component performs an actionEvent.
binding | The attribute takes a value-binding expression for a component property of a backing bean
converter | ID of a converter to be used or a reference to a converter.
id | Every component may have a unique id that is automatically created if omitted
name | A name of this parameter
noEscape | If set to true, the value will not enclosed within single quotes and there will be no escaping of characters. This allows the use of the value as JavaScript code for calculating value on the client-side. This doesn't work with non-AJAX components.
value | An initial value or a value binding

Table 6.6. Component identification parameters

Name | Value
--- | ---
component-type | org.ajax4jsf.ActionParameter
component-class | org.ajax4jsf.component.html.HtmlActionParameter

### 6.3.2. Creating on a page

Simple component definition example:

Example:

    <a4j:actionparam noEscape="true" name="param1" value="getMyValue()" assignTo="#{bean.prop1}" />

### 6.3.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlActionParameter;

    ...

    HtmlActionParameter myActionParameter = new HtmlActionParameter();

    ...

### 6.3.4. Key attributes and ways of usage

The component <a4j:actionparam> is a combination of the functionality of two JSF tags: <f:param> and <f:actionListener> .

At the render phase, it's decoded by parent component ( <h:commandLink> or like) as usual. At the process request phase, if the parent component performs an action event, update the "value" specified in the "assignTo" attribute as its "value" . If a "converter" attribute is specified, use it to encode and decode the "value" to a string stored in the html parameter.

<a4j:actionparam> has a "noEscape" attribute. If it is set to "true", the "value" is evaluated as a JavaScript code.

Example:

    ...

            <script>

                ...

                 var foo = "bar";

                ...

            </script>

            ...

            <a4j:actionparam noEscape="true" name="param1" value="foo" assignTo="#{bean.prop1}" />

    ...

The <a4j:param> extends <f:param> , so the "name" attribute is mandatory. Otherwise, the "value" misses due missing the request parameter name for it.

### 6.3.5. Relevant resources links

Here you can see the example of <a4j:actionparam> usage and sources for the given example.

More information can be found on the Ajax4jsf Users Forum.

## 6.4. < a4j:commandButton >

### 6.4.1. Description

The <a4j:commandButton> component is very similar to the <h:commandButton> component, the only difference is that an Ajax form submit is generated on a click and it allows dynamic rerendering after a response comes back. It's not necessary to plug any support into the component, as Ajax support is already built in.

Table 6.7. a4j : commandButton attributes

Attribute Name | Description
--- | ---
accesskey | This attribute assigns an access key to an element. An access key is a single character from the document character set. Note: Authors should consider the input method of the expected reader when specifying an accesskey
action | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only
alt | Alternate textual description of the element rendered by this component.

component-type | org.ajax4jsf.CommandButton
component-family | javax.faces.Command
component-class | org.ajax4jsf.component.html.HtmlAjaxCommandButton
renderer-type | org.ajax4jsf.components.AjaxCommandButtonRenderer

### 6.4.2. Creating on a page

The simplest tag usage example:

Example:

    ...

    <a4j:commandButton reRender="someData" action="#{bean.action1}" value="Link"/>

    ...

### 6.4.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlAjaxCommandButton;

    ...

    HtmlAjaxCommandButton myButton = new HtmlAjaxCommandButton();

    ...

### 6.4.4. Key attributes and ways of usage

<a4j:commandButton> is used in the same way as <h:commandButton> , but with definition of the area that is updated after the response comes back from the server.

This definition of the component provides a link, a click on the link causes an Ajax form submit on the server, `action1` method performance, and rendering of the component with `someData` id after the response comes back from the server.

The component <a4j:commandButton> placed on a page generates the following HTML code:

    ...

    <input type="submit" onclick="A4J.AJAX.Submit(...request parameters);return false;" value="sort"/>

    ...

Hence, the utility method `A4J.AJAX.Submit` is called on a click, the method performs Ajax request as the <a4j:support> component

## Note:

AJAX support is built in and it's not necessary to add nested <a4j:support> to the component.

The usage of the keyword `'this'` in JavaScript code in the "oncomplete" attribute depends on the location of <a4j:commandButton> . If the commandButton is situated outside the re-rendered region you can use keyword 'this' as in the following example:

    ...

    <h:form id="form">

      <a4j:commandButton id="cbutton" action="director.rollCamera"

               onclick="this.disabled=true"

               oncomplete="this.disabled=false" />

    </h:form>

    ...

Otherwise if the commandButton contained in re-rendered region the "oncomplete" attribute has a problem obtaining a reference of the commandButton object when using the keyword `'this'`. In this case you can use the "oncomplete" attribute as in the following example:

    ...

    <h:form id="form">

    <a4j:commandButton id="cbutton" action="director.rollCamera"

             onclick="this.disabled=true"

             oncomplete="document.getElementById('form:cbutton').disabled=false" />

    </h:form>

    ...

Common JSF navigation could be performed after an Ajax submit and partial rendering, but Navigation Case must be defined as <redirect/> in order to avoid problems with some browsers.

As any Core Ajax component sending Ajax requests and processing server responses <a4j:commandButton> has all attributes described above (see <a4j:support> chapter) that provide the required behavior of requests sending (delay, limitation of submit area and rendering, and etc.)

Information about the "process" attribute usage you can find here.

### 6.4.5. Relevant resources links

Here you can see the example of <a4j:commandButton> usage and sources for the given example.

## 6.5. < a4j:commandLink >

### 6.5.1. Description

The <a4j:commandLink> component is very similar to the <h:commandLink> component, the only difference is that an Ajax form submit is generated on a click and it allows dynamic rerendering after a response comes back. It's not necessary to plug any support into the component, as Ajax support is already built in.

Table 6.9. a4j : commandLink attributes

Attribute Name | Description
--- | ---
accesskey | This attribute assigns an access key to an element. An access key is a single character from the document character set. Note: Authors should consider the input method of the expected reader when specifying an accesskey

Possible combinations: * rect: left-x, top-y, right-x, bottom-y. * circle: center-x, center-y, radius. Note. When the radius value is percentage value, user agents should calculate the final radius value based on the associated object's width and height. The radius should be the smaller value of the two. * poly: x1, y1, x2, y2, ..., xN, yN. The first x and y coordinate pair and the last should be the same to close the polygon. When these coordinate values are not the same, user agents should infer an additional coordinate pair to close the polygon. Coordinates are relative to the top, left corner of the object. All values are lengths. All values are separated by commas

### 6.5.2. Creating on a page

To create the simplest variant on a page use the following syntax:

Example:

    ...

       <a4j:commandLink reRender="someData" action="#{bean.action1}" value="Link"/>

    ...

### 6.5.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlAjaxCommandLink;

    ...

    HtmlAjaxCommandLink myLink = new HtmlAjaxCommandLink();

    ...

### 6.5.4. Key attributes and ways of usage

<a4j:commandLink> is used in the same way as <h:commandLink> , but with definition of the area that is updated after the response comes back from the server.

This definition of the component provides a link, and a click on the link causes an Ajax form submit on the server, `"action1"` method performance, and rendering of the component with `"someData"` id after the response comes back from the server.

The component <a4j:commandLink> placed on a page generates the following HTML code:

    ...

    <a href="#" onclick="A4J.AJAX.Submit(?"request parameters"); return false;">

          <span>Link Value</span>

    </a>

    ...

Hence, the utility method `"A4J.AJAX.Submit"` is called on a click, the method performs Ajax request as the <a4j:support> component

## Note:

AJAX support is built in and it's not necessary to add nested <a4j:support> to the component.

Common JSF navigation could be performed after Ajax submit and partial rendering, but Navigation Case must be defined as <redirect/> in order to avoid problems with some browsers.

## 6.6. < a4j:form >

### 6.6.1. Description

The <a4j:form> component is very similar to the same component from the JSF HTML library, the only slight difference is in generation of links inside and possibility of Ajax by-default submission.

Table 6.11. a4j : form attributes

Attribute Name | Description
--- | ---
accept | This attribute specifies a comma-separated list of content types that a server processing this form will handle correctly. User agents may use this information to filter out non-conforming files when prompting you to select files to be sent to the server (cf. the INPUT element when type="file")
acceptCharset | This attribute specifies the list of character encodings for input data that is accepted by the server processing this form. The value is a space- and/or comma-delimited list of charset values. The client must interpret this list as an exclusive-or list, i.e., the server is able to accept any single character encoding per entity received. The default value for this attribute is the reserved string "UNKNOWN". User agents may interpret this value as the character encoding that was used to transmit the document containing this FORM element
ajaxSingle | boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only
ajaxSubmit | If "true", it becomes possible to set AJAX submission way for any components inside .
binding | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
data | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
enctype | This attribute specifies the content type used to submit the form to the server (when the value of method is "post"). The default value for this attribute is "application/x-www-form-urlencoded". The value "multipart/form-data" should be used in combination with the INPUT element, type="file"
eventsQueue | Name of requests queue to avoid send next request before complete other from same event. Can be used to reduce number of requests of frequently events (key press, mouse move etc.)
focus | id of element to set focus after request completed on client side
id | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
limitToList | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
onbeforedomupdate | JavaScript code for call before DOM has been updated on client side
oncomplete | JavaScript code for call after request completed on client side
onreset | The onreset event occurs when a form is reset. It only applies to the FORM element
onsubmit | The onsubmit event occurs when a form is submitted. It only applies to the FORM element
prependId | The flag indicating whether or not this form should prepend its id to its descendent id during the clientId generation process. If this flag is not set, the default value is "true".
process | Id['s] (in format of call UIComponent.findComponent()) of components, processed at the phases 2-5 in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
rendered | If "false", this component is not rendered
requestDelay | Attribute defines the time (in ms.) that the request will be wait in the queue before it is ready to send. When the delay time is over, the request will be sent to the server or removed if the newest 'similar' request is in a queue already
reRender | Id['s] (in format of call UIComponent.findComponent()) of components, rendered in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
status | ID (in format of call UIComponent.findComponent()) of Request status component
target | This attribute specifies the name of a frame where a document is to be opened. By assigning a name to a frame via the name attribute, authors can refer to it as the "target" of links defined by other elements
timeout | Timeout ( in ms ) for request.

component-family | javax.faces.Form
component-class | org.ajax4jsf.component.html.AjaxForm
renderer-type | org.ajax4jsf.FormRenderer

### 6.6.2. Creating on a page

Component definition on a page is similar to definition of the original component from JSF HTML library.

Example:

    <a4j:form>

           <h:panelGrid>

                        <h:commandButton value="Button" action="#{userBean.nameItMark}" />

           </h:panelGrid>

    </a4j:form>

### 6.6.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.AjaxForm;

    ...

    AjaxForm myForm = new AjaxForm();

    ...

### 6.6.4. Key attributes and ways of usage

The difference with the original component is that all hidden fields required for command links are always rendered and it doesn't depend on links rendering on the initial page. It solves the problem with invalid links that weren't rendered on a page immediately, but after some Ajax request.

Beginning with release 1.0.5 additional attributes that make this form variant universal have appeared.

If "ajaxSubmit" attribute is true, it becomes possible to set Ajax submission way for any components inside, i.e. not a page URL is used as an "action" attribute, but the javascript: `A4J.AJAX.Submit(...)`call. In this case, the "reRender" attribute contains a list of Ids of components defined for re-rendering. If you have <h:commandButton> or <h:commandLink> inside the form, they work as <a4j:commandButton> .

Example:

    <a4j:form id="helloForm" ajaxSubmit="true" reRender="table">

        ...

        <t:dataTable id="table"... >

            ...

        </t:dataTable>

        ...

        <t:datascroller for="table"... >

            ...

        </t:datascroller>

        ...

    </a4j:form

This example shows that in order to make <t:datascroller> submissions to be Ajax ones it's required only to place this <t:datascroller> into <a4j:form> . In the other case it is necessary to redefine renders for its child links elements that are defined as <h:commandLink> and can't be made Ajax ones with using e.g. <a4j:support> .

With the help of "limitToList" attribute you can limit areas, which are updated after the responses. If "limitToList" is true, only the reRender attribute is taken in account. Therefore, if you use blocks of text wrapped with <a4j:outputPanel> and `ajaxRendered= "true"`, blocks of text are ignored.

Information about the "process" attribute usage you can find here.

Here you can see the example of <a4j:form> usage and sources for the given example.

## 6.7. < a4j:htmlCommandLink >

### 6.7.1. Description

The <a4j:htmlCommandLink> component is very similar to the same component from the JSF HTML library, the only slight difference is in links generation and problem solving that occurs when an original component is used.

Table 6.13. a4j : htmlCommandLink attributes

Attribute Name | Description
--- | ---
accesskey | This attribute assigns an access key to an element. An access key is a single character from the document character set. Note: Authors should consider the input method of the expected reader when specifying an accesskey
action | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | MethodBinding pointing at method accepting an ActionEvent with return type void
binding | The attribute takes a value-binding expression for a component property of a backing bean
charset | The character encoding of a resource designated by this hyperlink
coords | This attribute specifies the position and shape on the screen. The number and order of values depends on the shape being defined. Possible combinations: * rect: left-x, top-y, right-x, bottom-y. * circle: center-x, center-y, radius. Note. When the radius value is percentage value, user agents should calculate the final radius value based on the associated object's width and height. The radius should be the smaller value of the two. * poly: x1, y1, x2, y2, ..., xN, yN. The first x and y coordinate pair and the last should be the same to close the polygon. When these coordinate values are not the same, user agents should infer an additional coordinate pair to close the polygon. Coordinates are relative to the top, left corner of the object. All values are lengths. All values are separated by commas
dir | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left)
disabled | When set for a form control, this boolean attribute disables the control for your input.
hreflang | Base language of a resource specified with the href attribute; hreflang may only be used with href

immediate | True means, that the default ActionListener should be executed immediately (i.e. during Apply Request Values phase of the request processing lifecycle), rather than waiting until the Invoke Application phase
lang | Code describing the language used in the generated markup for this component
onblur | JavaScript code. The onblur event occurs when an element loses focus either by the pointing device or by tabbing navigation. It may be used with the same elements as onfocus
onclick | HTML: a script expression; a pointer button is clicked
ondblclick | HTML: a script expression; a pointer button is double-clicked
onfocus | JavaScript code. The onfocus event occurs when an element gets focus
onkeydown | HTML: a script expression; a key is pressed down
onkeypress | HTML: a script expression; a key is pressed and released
onkeyup | HTML: a script expression; a key is released
onmousedown | HTML: script expression; a pointer button is pressed down
onmousemove | HTML: a script expression; a pointer is moved within
onmouseout | HTML: a script expression; a pointer is moved away
onmouseover | HTML: a script expression; a pointer is moved onto
onmouseup | HTML: script expression; a pointer button is released
rel | The relationship from the current document to the anchor specified by this hyperlink. The value of this attribute is a space-separated list of link types
rendered | If "false", this component is not rendered
rev | A reverse link from the anchor specified by this hyperlink to the current document. The value of this attribute is a space-separated list of link types
shape | This attribute specifies the shape of a region. The possible values are "default", "rect", "circle" and "poly".
style | CSS style(s) is/are to be applied when this component is rendered

### 6.7.2. Creating the Component with a Page Tag

Component definition on a page is the same as for the original component from the JSF HTML library.

Example:

    <a4j:htmlCommandLink value="value" action="action"/>

### 6.7.3. Creating the Component Dynamically Using Java

Example:

    import javax.faces.component.html.HtmlCommandLink;

    ...

    HtmlCommandLink myCommandLink = new HtmlCommandLink();

    ...

### 6.7.4. Key attributes and ways of usage

The difference with the original component is that all hidden fields required for command links with the child <f:param> elements are always rendered and it doesn't depend on links rendering on the initial page. It solves the problem with invalid links that weren't rendered on a page immediately, but after some Ajax request.

Example:

    <a4j:form>

        ...

        <a4j:htmlComandLink action="action" value="link" rendered="#{bean.rendered}">

            <f:param .../>

        <a4j:htmlComandLink>

        ...

    </a4j:form>

In this example <a4j:htmlCommandLink> works as standard <h:commandLink> , but here hidden fields required for correct functionality are rendered before the first downloading of a page, though it doesn't happen if its attribute isn't set to "false".

## 6.8. < a4j:jsFunction >

### 6.8.1. Description

The <a4j:jsFunction> component allows to invoke the server side data and return it in a JSON format to use in a client JavaScript calls.

Table 6.15. a4j : jsFunction attributes

Attribute Name | Description
--- | ---
action | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only
binding | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
data | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
eventsQueue | Name of requests queue to avoid send next request before complete other from same event. Can be used to reduce number of requests of frequently events (key press, mouse move etc.)
focus | id of element to set focus after request completed on client side
id | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
immediate | True means, that the default ActionListener should be executed immediately (i.e. during Apply Request Values phase of the request processing lifecycle), rather than waiting until the Invoke Application phase
limitToList | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
name | Name of generated JavaScript function definition
onbeforedomupdate | JavaScript code for call before DOM has been updated on client side
oncomplete | JavaScript code for call after request completed on client side
process | Id['s] (in format of call UIComponent.findComponent()) of components, processed at the phases 2-5 in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
rendered | If "false", this component is not rendered
requestDelay | Attribute defines the time (in ms.) that the request will be wait in the queue before it is ready to send. When the delay time is over, the request will be sent to the server or removed if the newest 'similar' request is in a queue already
reRender | Id['s] (in format of call UIComponent.findComponent()) of components, rendered in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
status | ID (in format of call UIComponent.findComponent()) of Request status component
timeout | Response waiting time on a particular request. If a response is not received during this time, the request is aborted

component-family | org.ajax4jsf.components.ajaxFunction
component-class | org.ajax4jsf.component.html.HtmlajaxFunction
renderer-type | org.ajax4jsf.components.ajaxFunctionRenderer

### 6.8.2. Creating on a page

Simple component definition example:

Example:

    ...

    <head>

        <script>

            <!--There is some script named "myScript" that uses parameters which will be taken from server-->

        </script>

    </head>

    <body>

    ...

    <a4j:jsFunction data="#{bean.someProperty}" name="callScript" oncomplete="myScript(data.subProperty1, data.subProperty2)"/>

    ...

The script `"myScript"` is called after `bean.someProperty` data is returned from server(e.g. It'll be object with two subproperties).

### 6.8.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlajaxFunction;

    ...

    HtmlajaxFunction myFunction = new HtmlajaxFunction();

    ...

### 6.8.4. Key attributes and ways of usage

As the component uses Ajax request to get data from server - it has all common Ajax Action attributes. Hence, "action" and "actionListener" can be invoked, and reRendering some parts of the page fired after calling function.

When using the <a4j:jsFunction> it's possible to initiate the Ajax request from the JavaScript and perform partial update of a page and/or invoke the JavaScript function with data returned by Ajax response.

    ...

    <body onload="callScript()">

        ...

        <h:form>

        ...

        <a4j:jsFunction name="callScript" data="#{bean.someProperty1}"

            reRender="someComponent" oncomplete="myScript(data.subProperty1, data.subProperty2)">

            <a4j:actionParam name="param_name" assignTo="#{bean.someProperty2}"/>

        </a4j:jsFunction>

        ...

        </h:form>

        ...

    </body>

    ...

The <a4j:jsFunction> allows to use <a4j:actionParam> or pure <f:param> for passing any number of parameters of the JavaScript function into Ajax request. <a4j:jsFunction> is similar to <a4j:commandButton> , but it could be activated from the JavaScript code. It allows to invoke some server side functionality and use the returned data in the JavaScript function invoked from "oncomplete" attribute. Hence it's possible to use <a4j:jsFunction> instead of <a4j:commandButton> . You can put it anywhere, just don't forget to use <h:form> ... </h:form> around it.

Information about the "process" attribute usage you can find here.

### 6.8.5. Relevant resources links

Here you can find additional information and example on how to use <a4j:jsFunction> with JSON.

Here you can see the example of <a4j:jsFunction> usage and sources for the given example.

Here you can found some additional information about <f:param> component.

## 6.9. < a4j:include >

### 6.9.1. Description

The <a4j:include> component is used for page areas update after an Ajax request according to the faces-config Navigation Rules and for implementation of wizard-like parts work in Ajax mode.

Table 6.17. a4j : include attributes

Attribute Name | Description
--- | ---
ajaxRendered | Defines, whether the content of this component must be (or not) included in AJAX response created by parent AJAX Container, even if it is not forced by reRender list of ajax action. Ignored if component marked to output by some Ajax action component. Default value is "true".
binding | The attribute takes a value-binding expression for a component property of a backing bean
dir | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left)
id | Every component may have a unique id that is automatically created if omitted
keepTransient | Flag for mark all child components to non-transient. If true, all children components will be set to non-transient state and keep in saved components tree. For output in self-renderer region all content ( By default, all content in <f:verbatim> tags and non-jsf elements in facelets, marked as transient - since, self-rendered ajax regions don't plain output for ajax processing ).
lang | Code describing the language used in the generated markup for this component
layout | HTML layout for generated markup. Possible values: "block" for generating an HTML <div> element, "inline" for generating an HTML <span> element, and "none" for generating no HTML element. There is a minor exception for the "none" case where a child element has the property "rendered" set to "false". In this case, we create an empty <span> element with same ID as the child element to use as a placeholder for later processing.
rendered | If "false", this component is not rendered
style | CSS style(s) is/are to be applied when this component is rendered
styleClass | Corresponds to the HTML class attribute
title | Advisory title information about markup elements generated for this component
viewId | viewId for included page.

Table 6.18. Component identification parameters

Name | Value
--- | ---
component-type | org.ajax4jsf.Include
component-family | javax.faces.Output
component-class | org.ajax4jsf.component.html.Include
renderer-type | org.ajax4jsf.components.AjaxIncludeRenderer

### 6.9.2. Creating on a page

To use the component, it's necessary to place the following strings on a page:

Example:

    <h:panelGroup id="wizard">

            <a4j:include  viewId="/pages/include/first.xhtml" />

    </h:panelGroup>

For navigation inside a page defined in viewId any components responsible for Ajax requests to the server generation are used.

For example, the following component on a page `"/pages/include/first.xhtml"`

Example:

    ...

    <a4j:commandButton action="next" reRender="wizard"/>

    ...

And in faces-config it's defined:

Example:

    <navigation-rule>

      <from-view-id>/pages/include/first.xhtml</from-view-id>

      <navigation-case>

       <from-outcome>next</from-outcome>

       <to-view-id>/pages/include/second.xhtml</to-view-id>

      </navigation-case>

     </navigation-rule>

In this case after a click on a button defined inside `"first.xhtml"` view, navigation is performed after an Ajax request (the same as standard JSF one) only inside this view.

### 6.9.3. Creating the Component Dynamically Using Java

    <import org.ajax4jsf.component.html.Include;

    ...

    Include myInclude = new Include();

    ...

If <a4j:include> is defined this way, any Ajax request returning outcome inside generates navigation with this <a4j:include> .

Ajax Action for navigation implementation inside view must be placed inside <a4j:include> pages. Navigation defined by these pages is applied to the <a4j:include> element current for them.

As in the general case for Ajax Action component, if the <a4j:action> component inside <a4j:include> returns outcome defined as <redirect/>, Ajax submit is performed with navigation of the whole page and not only of the current view.

### 6.9.4. Relevant resources links

Here you can see the example of <a4j:include> usage and sources for the given example.

Some additional information can be found on the Ajax4Jsf Users Forum.

## 6.10. < a4j:loadBundle >

### 6.10.1. Description

The <a4j:loadBundle> component is similar to the same component from the JSF Core library. The component loads a resource bundle localized for the Locale of the current view and exposes it (as a Map) in the request attributes of the current request.

Table 6.19. a4j : loadBundle attributes

Attribute Name | Description
--- | ---
basename | Base name of the resource bundle to be loaded.
binding | The attribute takes a value-binding expression for a component property of a backing bean
id | Every component may have a unique id that is automatically created if omitted
rendered | If "false", this component is not rendered
var | Name of a request scope attribute under which the resource bundle will be exposed as a Map.

component-type | org.ajax4jsf.Bundle
component-family | org.ajax4jsf.Bundle
component-class | org.ajax4jsf.component.html.AjaxLoadBundle

### 6.10.2. Creating on a page

To create the simplest variant on a page use the following syntax:

Example:

    <a4j:loadBundle baseName="demo.bundle.Messages" var="Message"/>

### 6.10.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.AjaxLoadBundle;

    ...

    AjaxLoadBundle myBundle = new AjaxLoadBundle();

    ...

### 6.10.4. Key attributes and ways of usage

<a4j:loadBundle> allows to use reference to bundle messages during the Ajax re-rendering. <a4j:loadBundle> is a substitute for the <f:loadBundle> in JSF 1.1 which is not a JSF component originally. <f:loadBundle> is a jsp tag that load the bundle messages into the request scope when page is rendered. As soon as each Ajax request works in own request scope, the bundles loaded with <f:loadBundle> are unavailable. Instead of <f:loadBundle> that might be located anywhere on a page, the <a4j:loadBundle> should be declared inside the <f:view> (this does not matter in case on using Facelets) JSF 1.2 introduces the bundle registered in the faces-config.xml. This fixed the problem with <f:loadBundle> . Therefore, you can use this JSF 1.2 way to declare your bundles.

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
id | Every component may have a unique id that is automatically created if omitted

component-type | org.ajax4jsf.Log
component-family | org.ajax4jsf.Log
component-class | org.ajax4jsf.component.html.AjaxLog
renderer-type | org.ajax4jsf.LogRenderer

### 6.13.2. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

    <a4j:log popup="false" level="ALL" style="width: 800px; height: 300px;"></a4j:log>

Then, in order to open a log window, press "CTRL+SHIFT+L" on a page with the component.

### 6.13.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.AjaxLog;

    ...

    AjaxLog myLog = new AjaxLog();

    ...

### 6.13.4. Key attributes and ways of usage

Usage of the appropriate component attributes could change a representation level of debug information as well as the hot key for a window opening.

The hot key could be changed with the "hotkey" attribute, where it's necessary to define one letter that together with "CTRL+SHIFT" opens a window.

The "level" attribute with several possible values ("FATAL", "ERROR", "WARN", "INFO", "ALL") could change a logging level.

The log could be generated not only in a new window, but also on the current page in a separate <div> , this is also controlled with the "popup" attribute on the component.

Example:

    <a4j:log level="ALL" popup="false" width="400" height="200"/>

The component defined this way is decoded on a page as <div> inside a page, where all the information beginning with informational message is generated.

## Note:

<a4j:log> is getting renewed automatically after execution of Ajax requests. Don't renew <a4j:log> by using reRender!

Possible combinations: * rect: left-x, top-y, right-x, bottom-y. * circle: center-x, center-y, radius. Note. When the radius value is percentage value, user agents should calculate the final radius value based on the associated object's width and height. The radius should be the smaller value of the two. * poly: x1, y1, x2, y2, ..., xN, yN. The first x and y coordinate pair and the last should be the same to close the polygon. When these coordinate values are not the same, user agents should infer an additional coordinate pair to close the polygon. Coordinates are relative to the top, left corner of the object.

mimeType | Geterated content mime-type for append to response header ( 'image/jpeg' etc )
onblur | JavaScript code. The onblur event occurs when an element loses focus either by the pointing device or by tabbing navigation. It may be used with the same elements as onfocus
onclick | HTML: a script expression; a pointer button is clicked
ondblclick | HTML: a script expression; a pointer button is double-clicked
onfocus | JavaScript code. The onfocus event occurs when an element gets focus
onkeydown | HTML: a script expression; a key is pressed down
onkeypress | HTML: a script expression; a key is pressed and released
onkeyup | HTML: a script expression; a key is released
onmousedown | HTML: script expression; a pointer button is pressed down
onmousemove | HTML: a script expression; a pointer is moved within
onmouseout | HTML: a script expression; a pointer is moved away

type | The content type of the resource designated by this hyperlink
uriAttribute | Name of attribute for resource-link attribute ( 'href' for <a>, 'src' for <img> or <script>, etc)
usemap | use client-side image map
value | Data value calculated at render time and stored in URI (also as part of cache Key ), at generation time passed to send method. Can be used for update cache at change of generating conditions, and for creating beans as "Lightweight" pattern components (request scope). IMPORTANT: Since serialized data stored in URI, avoid using big objects.

### 6.14.2. Creating on a page

Component definition on a page for graphical data output

Example:

    ...

    <a4j:mediaOutput element="img" cacheable="false" session="true"

        createContent="#{paintBean.paint}" value="#{paintData}"

        mimeType="image/jpeg"/>

    ...

### 6.14.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.MediaOutput;

    ...

    MediaOutput myMedia = new MediaOutput ();

    ...

### 6.14.4. Key attributes and ways of usage

To use the component it's necessary to define it on a page and set Java methods for data keeping and data transmission to output stream.

Here is the content of `paintData` that is a bean containing output data

Example:

    package demo;

    public class PaintData implements Serializable{

            private static final long serialVersionUID = 1L;

            Integer width=100;

            Integer weight=50;

    ...

The Paint method of the `paintBean` class is a method transmitting graphical data into output stream.

Example:

    public void paint(OutputStream out, Object data) throws IOException{

        <!--...Some code that puts binary data to "out" Stream-->

            }

As it was shown in the example above there are two main components:

- "createContent" specifies a method accepting 2 parameters. The first (of `java.io.OutputStream` type) defines a stream, where any binary data is output. The second (of `java.lang.Object` type) contains deserialized object with data specified in the "value" attribute.

- Value specifies a bean class keeping data for transmitting into a method that transmits it into a stream.

## Note:

A bean class transmitted into value should `implement Serializable` interface.

Hence, when using the component it's possible to output your data of any type on a page with Ajax requests.

Here you can see the example of <a4j:mediaOutput > usage and sources for the given example.

## 6.15. < a4j:outputPanel >

### 6.15.1. Description

The component is used for components grouping in the Ajax output area, which offers several additional output opportunities such as inserting of non-present in tree components, saving of transient elements after Ajax request and some others.

Table 6.29. a4j : outputPanel attributes

Attribute Name | Description
--- | ---
ajaxRendered | Defines, whether the content of this component must be (or not) included in AJAX response created by parent AJAX Container, even if it is not forced by reRender list of ajax action. Ignored if component marked to output by some Ajax action component. Default value is "false".
binding | The attribute takes a value-binding expression for a component property of a backing bean
dir | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left)
id | Every component may have a unique id that is automatically created if omitted
keepTransient | Flag to mark all child components to non-transient. If true, all children components will be set to non-transient state and keep in saved components tree. For output in self-renderer region all content ( By default, all content in <f:verbatim> tags and non-jsf elements in facelets, marked as transient - since, self-rendered ajax regions don't plain output for ajax processing ).
lang | Code describing the language used in the generated markup for this component
layout | HTML layout for generated markup. Possible values: "block" for generating an HTML <div> element, "inline" for generating an HTML <span> element, and "none" for generating no HTML element. There is a minor exception for the "none" case where a child element has the property "rendered" set to "false". In this case, we create an empty <span> element with same ID as the child element to use as a placeholder for later processing.
onclick | HTML: a script expression; a pointer button is clicked
ondblclick | HTML: a script expression; a pointer button is double-clicked
onkeydown | HTML: a script expression; a key is pressed down
onkeypress | HTML: a script expression; a key is pressed and released
onkeyup | HTML: a script expression; a key is released
onmousedown | HTML: script expression; a pointer button is pressed down
onmousemove | HTML: a script expression; a pointer is moved within
onmouseout | HTML: a script expression; a pointer is moved away
onmouseover | HTML: a script expression; a pointer is moved onto
onmouseup | HTML: script expression; a pointer button is released
rendered | If "false", this component is not rendered
style | CSS style(s) is/are to be applied when this component is rendered
styleClass | Corresponds to the HTML class attribute
title | Advisory title information about markup elements generated for this component

                        <h:form>

                            <h:outputText value="Some text"/>

                                <h:inputText id="text1" label="text1" value="#{rsBean.text1}">

                                </h:inputText>

                        </h:form>

            </a4j:outputPanel>

### 6.15.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlAjaxOutputPanel;

    ...

    HtmlAjaxOutputPanel  myPanel = new HtmlAjaxOutputPanel();

### 6.15.4. Key attributes and ways of usage

<a4j:outputPanel> allows marking of a page area, which is updated on Ajax response. Anyway, <a4j:outputPanel> usage is optional, as in RichFaces it's possible to indicate any existing component id on a component view in order to define updating areas. To speed up the performance, RichFaces updates only a component tree. <a4j:outputPanel> usage is recommended for wrapping components that aren't rendered during the primary non-ajax response, as the components don't present in a component tree.

Example:

    <a4j:support ... reRender="mypanel"/>

    ...

    <a4j:outputPanel id="mypanel">

      <h:panelGrid rendered="#{not empty foo.bar}">

        ...

      </h:panelGrid>

    </a4j:outputPanel>

In addition to the areas directly indicated in "reRender" attribute of Ajax components, <a4j:outputPanel> allows to update a part of a page basing on its own flag. The flag is defined by the "ajaxRendered" attribute. The flag is commonly used when a part of a page must be updated or can be updated on any response.

Example:

    <a4j:outputPanel ajaxRendered="true">

      <h:messages/>

    </a4j:outputPanel>

On default <a4j:outputPanel> is output as a pair of opening and closing html <span> tag, but with the help of the layout attribute this output way could be changed. There are three variants for this component value:

- "inline" (default)

- "block"

- "none"

If `layout="block"` is chosen, the component is rendered as a pair of opening and closing <div> tag, to which it's possible to apply any available style attributes available for block tags.

`layout ="none"` helps to avoid an unnecessary tag round a context that could or couldn't be rendered according to the defined "rendered" attribute conditions. If an inner context isn't rendered, <a4j:outputPanel> is rendered as a <span> tag with the id equal to an id of a child component and `display:none` style. If a child component is rendered, <a4j:outputPanel> doesn't present at all in a final code.

Example:

    <a4j:support .... reRender="mypanel"/>

    ...

    <a4j:outputPanel layout="none">

      <h:panelGrid id="mypanel" rendered="#{not empty foo.bar}">

        ...

      </h:panelGrid>

    </a4j:outputPanel>

As you see, the code is very similar to the one shown above, but "reRender " attribute refers directly to the updating panelGrid and not to the framing outputPanel, and it's more semantically correct.

<a4j:outPanel> should be used for non-JSF component part framing, which is to be updated on Ajax response, as RichFaces specifies the list of updating areas as a list of an existing JSF component.

On default non-JSF context isn't saved in a component tree, but is rendered anew every time. To accelerate the processing speed and Ajax response input speed, RichFaces saves non-JSF context in a component tree on default. This option could be canceled by "keepTransient" attribute that cancels transient flag forced setting for child components. This flag setting keeps the current value set by child components.

## Note:

In JSF 1.1 implementation and lower, where non-JSF context should be framed with the <f:verbatim> component, <a4j:outputPanel> doesn't improve this JSF implementation option in any way, so you still have to use this tag where it's necessary without RichFaces usage.

RichFaces allows setting Ajax responses rendering directly basing on component tree nodes without referring to the JSP (XHTML) page code. It could be defined by "selfRendered" attribute setting to "true" on <a4j:region> and could help considerably speed up a response output. However, if a transient flag is kept as it is, this rapid processing could cause missing of transient components that present on view and don't come into a component tree. Hence, for any particular case you could choose a way for you application optimization: speed up processing or redundant memory for keeping tree part earlier defined a transient.

### 6.16.2. Creating on a page

This component should be defined as a child component for <f:view>:

    <f:view>

     <a4j:page>

         <f:facet name="head">

             <!--...Head Content here-->

         </f:facet>

       <!--...Page Content here-->

     </a4j:page>

    </f:view>

### 6.16.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlPage;

    ...

    HtmlPage myPage = new HtmlPage();

    ...

### 6.16.4. Key attributes and ways of usage

The component is mostly used to solve the following problem with MyFaces for erlier Ajax4jsf versions: in MyFaces <f:view> doesn't get control over the RENDER_RESPONSE phase, thus Ajax can't get control and make a response also. To avoid this problem it was necessary to use <a4j:page> on a page round the Ajax updatable area. In the last versions of both frameworks the problem is successfully fixed and no <a4j:page> usage is required.

The component is rendered as a full HTML page template as it is shown in the example. The head section is defined with the help of the corresponding "head" facet. You do not need to use "body" facet in order to define first body section. The second and more body sections is defined with the help of the corresponding "body" facet.

The attribute "format" defines page layout format for encoding DOCTYPE.

The attribute "pageTitle" is rendered as title section.

Example:

    <a4j:page format="xhtml" pageTitle="myPage">

        <f:facet name="head">

            <!--Head Content here-->

        </f:facet>

       <!--Page Content Here-->

    </a4j:page>

This structure is rendered as:

Example:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

    <html>

        <head>

            <title>myPage</title>

            <!--Head Content here-->

        </head>

        <body>

            <!--Page Content Here-->

        </body>

    </html>

## 6.17. < a4j:poll >

### 6.17.1. Description

The <a4j:poll> component allows periodical sending of Ajax requests to a server and is used for a page updating according to a specified time interval.

Table 6.33. a4j : poll attributes

Attribute Name | Description
--- | ---
action | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only
binding | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
data | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
enabled | Enables/disables polling. Default value is "true".
eventsQueue | Name of requests queue to avoid send next request before complete other from same event. Can be used to reduce number of requests of frequently events (key press, mouse move etc.)
focus | id of element to set focus after request completed on client side
id | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
immediate | True means, that the default ActionListener should be executed immediately (i.e. during Apply Request Values phase of the request processing lifecycle), rather than waiting until the Invoke Application phase
interval | Interval (in ms) for call poll requests. Default value is "1000"ms (1 second).
limitToList | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
onbeforedomupdate | JavaScript code for call before DOM has been updated on client side
oncomplete | JavaScript code for call after request completed on client side
onsubmit | JavaScript code for call before submission of ajax event
process | Id['s] (in format of call UIComponent.findComponent()) of components, processed at the phases 2-5 in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
rendered | If "false", this component is not rendered
reRender | Id['s] (in format of call UIComponent.findComponent()) of components, rendered in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
status | ID (in format of call UIComponent.findComponent()) of Request status component
timeout | Timeout (in ms) for request

### 6.17.2. Creating on a page

To create the simplest variant on a page use the following syntax:

Example:

    <a4j:poll interval="500" reRender="grid"/>

### 6.17.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.AjaxPoll;

    ...

    AjaxPoll myPoll = new AjaxPoll();

    ...

### 6.17.4. Key attributes and ways of usage

The <a4j:poll> componet is used for periodical polling of server data. In order to use the component it's necessary to set an update interval. The "interval" attribute defines an interval in milliseconds between the previous response and the next request. The total period beetween two requests generated by the <a4j:poll> component is a sum of an "interval" attribute value and server response time. Default value for "interval" attribute is set to "1000" milliseconds (1 second). See an example of definition in the "Creating on a page" section.

The "timeout" attribute defines response waiting time in milliseconds. If a response isn't received during this period a connection is aborted and the next request is sent. Default value for "timeout" attribute isn't set.

The "enabled" attribute defines should the <a4j:poll> send request or not. It's necessary to render the <a4j:poll> to apply the current value of "enabled" attribute. You can use an EL-expression for "enabled" attribute to point to a bean property. An example of usage of mentioned above attributes is placed below:

Example:

    ...

        <a4j:region>

            <h:form>

                <a4j:poll id="poll" interval="1000" enabled="#{userBean.pollEnabled}" reRender="poll,grid"/>

            </h:form>

        </a4j:region>

        <h:form>

            <h:panelGrid columns="2" width="80%" id="grid">

                <h:panelGrid columns="1">

                    <h:outputText value="Polling Inactive" rendered="#{not userBean.pollEnabled}"></h:outputText>

                    <h:outputText value="Polling Active" rendered="#{userBean.pollEnabled}"></h:outputText>

                    <a4j:commandButton style="width:120px" id="control"

                                       value="#{userBean.pollEnabled?'Stop':'Start'} Polling"

                                       reRender="poll, grid">

                        <a4j:actionParam name="polling" value="#{!userBean.pollEnabled}"

                                         assignTo="#{userBean.pollEnabled}"/>

                    </a4j:commandButton>

                </h:panelGrid>

                    <h:outputText id="serverDate" style="font-size:16px" value="Server Date: #{userBean.date}"/>

            </h:panelGrid>

        </h:form>

    ...

The example shows how date and time are updated on a page in compliance with data taken from a server. The <a4j:poll> componet sends requests to the server every second. "reRender" attribute for <a4j:poll> contains value of its own Id. Hence, it renders itself for applying the current value of "enabled" attribute.

## Note:

The form around the <a4j:poll> component is required.

Information about the "process" attribute usage you can find here.

## 6.18. < a4j:portlet >

### 6.18.1. Description

The <a4j:portlet> component is DEPRECATED as far as JSR-301 was defined a same functionality for a UIViewRoot component. Thus, it is implicitly defined by mandatory <f:view> component.

    ...

### 6.18.4. Key attributes and ways of usage

The main component purpose is realization of possibility to create several instances the same portlet on one page. But clientId of elements should be different for each window. In that case namespace is used for each portlet. The <a4j:portlet> `implemets NaimingContainer` interface and adds namespace to all componets on a page. All portlet content should be wrapped by <a4j:portlet> for resolving problems mentioned before.

## 6.19. < a4j:push >

### 6.19.1. Description

The <a4j:push> periodically perform Ajax request to server, to simulate 'push' data.

The main difference between <a4j:push> and <a4j:poll> components is that <a4j:push> makes request to minimal code only (not to JSF tree) in order to check the presence of messages in the queue. If the message exists the complete request is performed. The component doesn't poll registered beans but registers `EventListener` which receives messages about events.

### 6.19.3. Creating the Component Dynamically Using Java

    import org.ajax4jsf.component.html.AjaxPush;

    ...

    AjaxPush myPush = new AjaxPush();

    ...

### 6.19.4. Key attributes and ways of usage

The <a4j:push> implements reverse Ajax technique.

The bean, for example, could be subscribed to Java Messaging Service (JMS) topic or it could be implemented as Message Driven Bean (MDB) in order to send a message to the <a4j:push> component about an event presence. In the presence of the event some action occurs.

Thus, a work paradigm with the <a4j:push> component corresponds to an anisochronous model, but not to pools as for <a4j:poll> component. See the simplest example below:

Example:

    ...

    class MyPushEventListener implements PushEventListener {

        public void onEvent(EventObject evt) {

            System.out.println(evt.getSource());

                //Some action

        }

    ...

Code for `EventListener` registration in the bean is placed below:

Example:

    ...

    public void addListener(EventListener listener) {

    synchronized (listener) {

            if (this.listener != listener) {

            this.listener = (PushEventListener) listener;

    }

    ...

A page code for this example is placed below.

Example:

    ...

        <a4j:status startText="in progress" stopText="done"/>

         <a4j:form>

            <a4j:region>

                <a4j:push reRender="msg" eventProducer="#{pushBean.addListener}" interval="2000"/>

            </a4j:region>

            <a4j:outputPanel id="msg" >

                <h:outputText value="#{pushBean.date}">

                    <f:convertDateTime type="time"/>

                </h:outputText>

            </a4j:outputPanel>

            <a4j:commandButton value="Push!!" action="#{pushBean.push}" ajaxSingle="true"/>

        </a4j:form>

    ...

The example shows how date is updated on a page in compliance with data taken from a server. In the example "interval" attribute has value "2000". This attribute defines an interval in milliseconds between the previous response and the next request. Default value is set to "1000" milliseconds (1 second). It's possible to set value equal to "0". In this case connection is permanent.

The "timeout" attribute defines response waiting time in milliseconds. If a response isn't received during this period a connection is aborted and the next request is sent. Default value for "timeout" attribute isn't set. Usage of "interval" and "timeout" attributes gives an opportunity to set short polls of queue state or long connections.

## Note:

The form around the <a4j:push> component is required.

Information about the "process" attribute usage you can find here.

### 6.19.5. Relevant resources links

Here you can found some additional information for <a4j:push> component usage.

## 6.20. < a4j:region >

### 6.20.1. Description

The <a4j:region> component defines an area that is decoded on the server after Ajax submission.

Table 6.39. a4j : region attributes

Attribute Name | Description
--- | ---
ajaxListener | MethodExpression representing an action listener method that will be notified when this component is activated by the ajax Request and handle it. The expression must evaluate to a public method that takes an AjaxEvent parameter, with a return type of void
binding | The attribute takes a value-binding expression for a component property of a backing bean
id | Every component may have a unique id that is automatically created if omitted
immediate | Flag indicating that, if this component is activated by ajaxrequest, notifications should be delivered to interested listeners and actions immediately (that is, during Apply Request Values phase) rather than waiting until Invoke Application phase
rendered | If "false", this component is not rendered
renderRegionOnly | Flag to disable rendering in AJAX responses content outside of active region. If this attribute set to "true" , no one of the components outside of region will be included to AJAX response. If set to "false", search for components to include in response will be performed on all tree. Default value is "false".
selfRendered | if "true", self-render subtree at InvokeApplication ( or Decode, if immediate property set to true ) phase

                        <h:inputText value="#{userBean.name}">

                            <a4j:support event="onkeyup" reRender="outname" />

                        </h:inputText>

                    </a4j:region>

### 6.20.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlAjaxRegion;

    ...

    HtmlAjaxRegion newRegion = new HtmlAjaxRegion();

    ...

### 6.20.4. Key attributes and ways of usage

The region is a component used for manipulation with components sent to the server. It sets particular processing parameters for an area on the server, i.e. the region deals with data input on the server and has no direct impact on output. To read more on the components responsible for out, see "reference" here.

The region marks an area page that is decoded on the server. In most cases it is not necessary to use the region, as ViewRoot is a default region. This component helps to reduce data quantity processed by the server, but the region doesn't influence on the standard submission rules. It means that:

- The area that is to be submitted onto the server should be embedded in <h:form>/<a4j:form> component.

- The whole form is submitted on Ajax response and not a region that request is performed from.

Example:

    <h:form id="form1">

        <a4j:region>

            <a4j:commandLink reRender="someID" value="Link" id="link1"/>

            <!--..Some content that will be decoded on server after Ajax request.-->

        </a4j:region>

    <h:form>

Hence, the <a4j:commandLink> request generation causes full `form1` form submission onto the server, the only difference is that a component tree part decoded on the serve is the part included into the region.

The regions could be nested in any order, the server picks out and decodes only the region, which contains a particular component that sends a request.

Example:

    <a4j:region>

        <a4j:commandLink reRender="someID" value="Link" id="link1"/>

        <a4j:region>

            <a4j:commandLink reRender="someID" value="Link" id="link2"/>

            <!--..Some content that will be decoded on server after Ajax request.-->

        </a4j:region >

        <!--..Some content that will be decoded on server after Ajax request.-->

    </a4j:region >

Therefore, the external region is decoded for the `"link1"` and the internal one is decoded for the `"link2"`.

RichFaces allows setting Ajax responses rendering directly basing on component tree nodes without referring to the JSP (XHTML) page code. It could be defined by "selfRendered" attribute setting to "true" on <a4j:region> and could help considerably speed up a response output. However, this rapid processing could cause missing of transient components that present on view and don't come into a component tree as well as omitting of <a4j:outputPanel> usage described below.

Example:

    <a4j:region selfRendered ="true">

        <a4j:commandLink reRender="someID" value="Link" id="link1"/>

        <!--..Some content with HTML used ("br","h1" and other tags used)-->

    </a4j:region >

In this case, the processing is quicker and going on without referring to a page code, but the HTML code that isn't saved in a component tree could be lost. Thus, this optimization should be very carefully performed and a usage of the additional components RichFaces ( <a4j:outputPanel> ) is required.

The processing could be also accelerated if a region decoded for the processing passes straight away into Encode. But to update some data out of the region or on another region, use the "renderRegionOnly" attribute set to "false" ("true" on default) to change this behaviour.

Example:

    <a4j:region renderRegionOnly="true">

        <a4j:commandLink reRender="someID2" value="Link1" id="link1"/>

        <h:panelGroup id="someId1">

        </h:panelGroup>

    </a4j:region>

    <a4j:region renderRegionOnly="false">

        <a4j:commandLink reRender="someID1" value="Link2" id="link2"/>

        <h:panelGroup  id="someId1">

        </h:panelGroup>

    </a4j:region>

This example shows that one of the regions is decoded when a link is used inside. Nevertheless, if after processing the `"link1"` is clicked, the first region passes into Encode as a root region and encode performance time is reduced. This optimization doesn't allow data update out of the region and should be implemented very carefully. The data out of the region described with `renderRegionOnly="false"` is updated successfully.

Starting from version 3.2.0 <a4j:region> can be used inside any iterative component (e.g. <rich:column> , <rich:scrollableDataTable> ) and just re-render the components from the same row without updating the whole table and without any additional listeners.

Example:

    <rich:column>

           <a4j:region>

                  <a4j:commandLink reRender="out"/>

           </a4j:region>

    </rich:column>

    <rich:column>

            <h:outputText id="out">

    </rich:column>

Here you can see the example of <a4j:region> usage and sources for the given example.

## 6.21. < a4j:repeat >

### 6.21.1. Description

The <a4j:repeat> component implements a basic iteration component allowing to update a set of its children with AJAX.

Table 6.41. a4j : repeat attributes

Attribute Name | Description
--- | ---
ajaxKeys | This attribute defines row keys that are updated after an AJAX request.
binding | The attribute takes a value-binding expression for a component property of a backing bean
componentState | It defines EL-binding for a component state for saving or redefinition.
first | A zero-relative row number of the first row to display
id | Every component may have a unique id that is automatically created if omitted
rendered | If "false", this component is not rendered
rowKeyConverter | Converter for a row key object
rowKeyVar | The attribute provides access to a row key in a Request scope.
rows | A number of rows to display, or zero for all remaining rows in the table
stateVar | The attribute provides access to a component state on the client side.
value | The current value for this component.
var | A request-scope attribute via which the data object for the current row will be used when iterating

### 6.21.2. Creating on a page

The component definition on a page is the same as for the facelets component:

    <a4j:repeat id="detail" value="#{bean.props}" var="detail">

        <h:outputText value="#{detail.someProperty}"/>

    </a4j:repeat>

The output is generated according to a collection contained in `bean.props` with the `detail` key passed to child components.

### 6.21.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlAjaxRepeat;

    ...

    HtmlAjaxRepeat repeater = new HtmlAjaxRepeat ();

    ...

### 6.21.4. Key attributes and ways of usage

The main difference of this component from iterative components of other libraries is a special "ajaxKeys" attribute. This attribute defines row keys that are updated after an Ajax request. As a result it becomes easier to update several child components separately without updating the whole page.

    ...

        <a4j:poll intervall="1000" action="#{repeater.action}" reRender="text">

            <table>

                <tbody>

                    <a4j:repeat value="#{bean.props}" var="detail" ajaxKeys="#{repeater.ajaxedRowsSet}">

                        <tr>

                            <td>

                                <h:outputText value="detail.someProperty" id="text"/>

                            </td>

                        </tr>

                    </a4j:repeat>

                </tbody>

            </table>

        </a4j:poll>

    ...

Thus, a list with a table structure from `bean.props` is output.

In the above-mentioned example the component <a4j:poll> sends Ajax requests every second, calling the `action` method of the `repeater` bean.

## Note:

The <a4j:repeater> component is defined as fully updated, but really updated there are only the row keys which "rowKeys" includes into the set "ajaxRowSet" defined in the "ajaxKeys" attribute

The set could be defined during the action method processing using data on a model from the property `repeater.myRepeat`

One more benefit of this component is absence of strictly defined markup as JSF HTML DataTable and TOMAHAWK DataTable has, hence the components could be used more flexibly anywhere where it's necessary to output the results of selection from some collection.

The next example shows collection output as a plain HTML list:

    <ul>

          <a4j:repeat ...>

            <li>...<li/>

             ...

            <li>...<li/>

          </a4j:repeat>

    </ul>

All other general attributes are defined according to the similar attributes of iterative components ( <h:dataTable> or <ui:repeat> ) and are used in the same way.

## 6.22. < a4j:status >

### 6.22.1. Description

The <a4j:status> component generates elements for displaying of the current Ajax requests status. There are two status modes: Ajax request is in process or finished.

Table 6.43. a4j : status attributes

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
dir | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left)

renderer-type | org.ajax4jsf.components.AjaxStatusRenderer

### 6.22.2. Creating on a page

There are two ways to define elements indicating a request status :

- With "StartText"/"StopText" atributes:

      <a4j:status startText="Progress" stopText="Done" for="stat1">

  In this case, text elements for the corresponding status are generated.

- With "Start" / "Stop" facets definition:

      <a4j:status for="stat2">

          <f:facet name="start">

              <h:graphicImage value="ajax_process.png" />

          </f:facet>

          <f:facet name="stop">

              <h:graphicImage value="ajax_stoped.png" />

          </f:facet>

      </a4j:status>

  In this case, the elements are generated for each status and correspond the facets content.

### 6.22.3. Creating the Component Dynamically Using Java

Example:

    import org.ajax4jsf.component.html.HtmlAjaxStatus;

    ...

    HtmlAjaxStatus  myStatus = new HtmlAjaxStatus();

    ...

### 6.22.4. Key attributes and ways of usage

There are two ways for the components or containers definition, which Ajax requests status is tracked by a component.

- Definition with the "for" attribute on the <a4j:status> component. Here "for" attribute should point at an Ajax container ( <a4j:region> ) id, which requests are tracked by a component.

- Definition with the "status" attribute obtained by any RichFaces library action component. The attribute should point at the <a4j:status> component id. Then this <a4j:status> component shows the status for the request fired from this action component.

The component creates two <span> or <div> elements depending on attribute "layout" with content defined for each status, one of the elements (start) is initially hidden. At the beginning of an Ajax request, elements state is inversed, hence the second element is shown and the first is hidden. At the end of a response processing, elements display states return to its initial values.

Example:

    <a4j:status startText="Started" stopText="stopped" />

The code shown in the example above is decoded on a page as:

    <span id="j_id20:status.start" style="display: none">

          Started

    </span>

    <span id="j_id20:status.stop">

            Stopped

    </span>

and after the generation of an Ajax response is changed to:

    <span id="j_id20:status.start">

            Started

    </span>

    <span id="j_id20:status.stop" style="display: none">

            Stopped

    </span>

There is a possibility to group a <a4j:status> elements content into <div> elements, instead of <span> . To use it, just redefine the "layout" attribute from "inline" (default) to "block".

Here you can find information on how to show a "Please Wait" box and block the input while the Ajax request is processed using combination of <a4j:status> and <rich:modalPanel> components .

Here you can see the example of <a4j:status> usage and sources for the given example.

## 6.23. < a4j:support >

### 6.23.1. Description

The <a4j:support> component adds an Ajax support to any existing JSF component. It allows a component to generate asynchronous requests on the necessary event demand and with partial update of page content after a response incoming from the server.

Table 6.45. a4j : support attributes

Attribute Name | Description
--- | ---
action | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only
binding | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
data | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
disabled | If "true", disable this component on page.
disableDefault | Disables default action for target event ( append "return false;" to JavaScript )
event | Name of JavaScript event property ( onclick, onchange, etc.) of parent component, for which we will build AJAX submission code
eventsQueue | Name of requests queue to avoid send next request before complete other from same event. Can be used to reduce number of requests of frequently events (key press, mouse move etc.)
focus | id of element to set focus after request completed on client side
id | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
immediate | True means, that the default ActionListener should be executed immediately (i.e. during Apply Request Values phase of the request processing lifecycle), rather than waiting until the Invoke Application phase
limitToList | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
onbeforedomupdate | JavaScript code for call before DOM has been updated on client side
oncomplete | JavaScript code for call after request completed on client side
onsubmit | JavaScript code for call before submission of ajax event
process | Id['s] (in format of call UIComponent.findComponent()) of components, processed at the phases 2-5 in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
rendered | If "false", this component is not rendered
requestDelay | Attribute defines the time (in ms.) that the request will be wait in the queue before it is ready to send. When the delay time is over, the request will be sent to the server or removed if the newest 'similar' request is in a queue already
reRender | Id['s] (in format of call UIComponent.findComponent()) of components, rendered in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
status | ID (in format of call UIComponent.findComponent()) of Request status component
timeout | Timeout (in ms) for request

### 6.23.2. Creating on a page

To use a component, place <a4j:support> as nested to the component requesting Ajax functionality and specify an event of a parent component that generates Ajax request and the components to be rerendered after a response from the server.

Example:

    <h:inputText value="#{bean.text}">

        <a4j:support event="onkeyup" reRender="repeater"/>

    </h:inputText>

    <h:outputText id="repeater" value="#{bean.text}"/>

On every keyup event generated by an input field, a form is submitted on the server with the help of Ajax and on a response coming from the server, element with `repeater` id, founded in a DOM tree is redrawn according to a new data from the response.

### 6.23.3. Creating the Component Dynamically Using Java

In order to add <a4j:support> in Java code you should add it as facet , not children:

Example:

    HtmlInputText inputText = new HtmlInputText();

    ...

    HtmlAjaxSupport ajaxSupport = new HtmlAjaxSupport();

          ajaxSupport.setActionExpression(FacesContext.getCurrentInstance().getApplication().getExpressionFactory().createMethodExpression(

              FacesContext.getCurrentInstance().getELContext(), "#{bean.action}", String.class, new Class[] {}));

          ajaxSupport.setEvent("onkeyup");

          ajaxSupport.setReRender("output");

          inputText.getFacets().put("a4jsupport", ajaxSupport);

### 6.23.4. Key attributes and ways of usage

<a4j:support> addition is very similar to correspondent event redefinition of a component, i.e.

Example:

    ...

    <h:inputText value="#{bean.text}">

        <a4j:support event="onkeyup" reRender="output" action="#{bean.action}"/>

    </h:inputText>

    ...

Is decoded on a page as:

Example:

    <input  onkeyup="A4J.AJAX.Submit( Some request parameters )"/>

As you see from the code, the "onkeyup" event calls a utility RichFaces method that submit a form creating a special marks for a filter informing that it is an Ajax request. Thus, any supports quantity could be added to every component, the supports define component behavior on these events.

## Note

The components: <a4j:commandLink> , <a4j:commandButton> , <a4j:poll> and others from RichFaces library are already supplied with <a4j:support> functionality and there is no necessity to add the support to them.

With the help of "onsubmit" and "oncomplete" attributes the component allows using JavaScript before (for request sending conditions checking) and after an Ajax response processing termination (for performance of user-defined activities on the client)

Example:

    <h:selectOneMenu value="#{bean.text}">

        <f:selectItem itemValue="First Item" itemLabel="First Item"/>

        <f:selectItem itemValue=" Second Item" itemLabel="Second Item"/>

        <f:selectItem itemValue=" Third Item" itemLabel="Third Item"/>

            <a4j:support event="onblur" reRender="panel" onsubmit="if(!confirm('Are you sure to change the option ?'))

                        {form.reset(); return false;}" oncomplete="alert('Value succesfully stored')"/>

    </h:selectOneMenu>

In example there is the condition checking (confirm) is used before request sending and message printing after the request processing is over.

The components allows different Ajax request managing ways for its various optimization in particular conditions such as:

- Limitation of the submit area and updating area for the request.

  "ajaxSingle" is an attribute that allows submission on the server only component sending a request, as if the component presented on a separate form.

  "limitToList" is an attribute that allows to limit areas, which are updated after the responses. Only these components defined in the "reRender" attribute are updated.

Example 1:

    <h:form>

        <h:inputText value="#{person.name}">

            <a4j:support event="onkeyup" reRender="test" ajaxSingle="true"/>

        </h:inputText>

        <h:inputText value="#{person.middleName}"/>

    </form>

In this example the request contains only the input component causes the request generation, not all the components contained on a form, because of `ajaxSingle="true"` usage.

Example 2:

    <h:form>

        <a4j:outputPanel ajaxRendered="true">

            <h:messages/>

        </a4j:outputPanel>

        <h:inputText value="#{person.name}">

            <a4j:support event="onkeyup" reRender="test" limitToList="true"/>

        </h:inputText>

        <h:outputText value="#{person.name}" id="test"/>

    </form>

In this example the component <h:messages> is always updated (as it capturing all Ajax requests, located in ajaxRendered <a4j:outputPanel> ), except the case when a response is sent from the input component from the example. On sending this component marks that updating area is limited to the defined in it components, it means that on its usage with `limitToList="true"` the only component updated is the one with `id="test"`.

- Limitation of requests frequency and updates quantity after the responses.

  "requestDelay" is an attribute that defines a time interval in seconds minimally permissible between responses.

  "eventQueue" is an attribute for naming of the queue where the next response is kept in till its processing, but if the next event comes in till this time is over, the waiting event is taken away, replacing with a new one.

  "ignoreDupResponces" is an attribute that allows to disable any updates on the client after an Ajax request if another Ajax request is already sent.

  "timeout" is an attribute that allows to set a time interval in millisecond to define a maximum time period of response wait time. In case of the interval interaction, a new request is sent and the previous one is canceled. Postprocessing of a response isn't performed.

  Example:

      <h:form>

          <h:inputText value="#{person.name}">

             <a4j:support event="onkeyup" reRender="test"

             requestDelay="1000" ignoreDupResponces="true" eventsQueue="myQueue"/>

          </h:inputText>

          <h:outputText value="#{person.name}" id="test"/>

      </form>

  This example clearly shows mentioned above attributes. If quick typing in a text field happens, every next requests sending is delayed for a second and requests quantity is reduced. The requests are kept in the queue till its the sending. Moreover, if the next request is already sent, the rerendering after the previous request is banned, and it helps to avoid unnecessary processing on the client.

Information about the "process" attribute usage you can find here.

- Event based validation triggering

Table 6.47. rich : ajaxValidator attributes

Attribute Name | Description
--- | ---
ajaxListener | MethodExpression representing an action listener method that will be notified when this component is activated by the ajax Request and handle it. The expression must evaluate to a public method that takes an AjaxEvent parameter, with a return type of void
binding | The attribute takes a value-binding expression for a component property of a backing bean
data | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
disableDefault | disableDefault
event | Name of JavaScript event property ( onclick, onchange, etc.) of parent component by which validation will be triggered
eventsQueue | Name of requests queue to avoid send next request before complete other from same event. Can be used to reduce number of requests of frequently events (key press, mouse move etc.)
focus | id of element to set focus after request completed on client side
id | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
limitToList | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
onbeforedomupdate | JavaScript code for call before DOM has been updated on client side
oncomplete | JavaScript code for call after request completed on client side
onsubmit | JavaScript code for call before submission of ajax event
rendered | If "false", this component is not rendered
requestDelay | Attribute defines the time (in ms.) that the request will be wait in the queue before it is ready to send. When the delay time is over, the request will be sent to the server or removed if the newest 'similar' request is in a queue already
reRender | Id['s] (in format of call UIComponent.findComponent()) of components, rendered in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
status | ID (in format of call UIComponent.findComponent()) of Request status component
summary | Summary message for a validation errors.
timeout | Response waiting time on a particular request. If a response is not received during this time, the request is aborted

### 6.24.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <h:outputText value="Name:" />

    <h:inputText value="#{userBean.name}" id="name" required="true">

           <f:validateLength minimum="3" maximum="12"/>

           <rich:ajaxValidator event="onblur"/>

    </h:inputText>

    ...

### 6.24.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlCalendar;

    ...

    HtmlAjaxValidator myAjaxValidator= new HtmlAjaxValidator();

    ...

### 6.24.5. Details of Usage

The <rich:ajaxValidator> component should be added as a child component to an input JSF tag which data should be validated and an event that triggers validation should be specified as well. The component is ajaxSingle by default so only the current field will be validated.

The following example demonstrates how the <rich:ajaxValidator> adds AJAX functionality to standard JSF validators. The request is sent when the input field loses focus, the action is determined by the "event" attribute that is set to `"onblur"`.

    ...

    <rich:panel>

           <f:facet name="header">

                  <h:outputText value="User Info:" />

           </f:facet>

           <h:panelGrid columns="3">

                  <h:outputText value="Name:" />

                  <h:inputText value="#{userBean.name}" id="name" required="true">

                         <f:validateLength minimum="3" maximum="12"/>

                                <rich:ajaxValidator event="onblur"/>

                  </h:inputText>

                  <rich:message for="name" />

           </h:panelGrid>

    </rich:panel>

    ...

This is the result of the snippet.

Figure 6.1. Simple example of <rich:ajaxValidator> with

In the example above it's show how to work with standard JSF validators. The <rich:ajaxValidator> component also works perfectly with custom validators enhancing their usage with AJAX.

Custom validation can be performed in two ways:

- Using JSF Validation API is available in javax.faces.validator package

- Using Hibernate Validator, specifying a constraint for the data to be validated. A reference on Hibernate Validator can be found here.

The following example shows how the data entered by user can be validated using Hibernate Validator.

    ...

    <rich:panel>

           <f:facet name="header">

                  <h:outputText value="User Info:" />

           </f:facet>

           <h:panelGrid columns="3">

                  <h:outputText value="Name:" />

                  <h:inputText value="#{validationBean.name}" id="name" required="true">

                         <rich:ajaxValidator event="onblur" />

                  </h:inputText>

                  <rich:message for="name" />

           </h:panelGrid>

    </rich:panel>

    ...

Here is the source code of the managed bean.

    ...

    package org.richfaces.demo.validation;

    import org.hibernate.validator.NotEmpty;

    import org.hibernate.validator.Email;

    import org.hibernate.validator.Length;

    public class ValidationBean {

        @NotEmpty

        @Length(min=3,max=12)

        private String name;

        @Email (message="wrong email format")

        @NotEmpty

        private String email;

        public ValidationBean() {

        }

        public String getName() {

            return name;

        }

        public void setName(String name) {

            this.name = name;

        }

        public String getEmail() {

            return email;

        }

        public void setEmail(String email) {

            this.email = email;

        }

    }

    ...

By default the Hibernate Validator generates an error message in 10 language, though you can redefine the messages that are displayed to a user when validation fails. In the shows example it was done by adding `(message="wrong email format")` to the `@Email` annotation.

This is how it looks.

## 6.25. < rich:graphValidator >

### 6.25.1. Description

The <rich:ajaxGraph> component allows to register Hibernate Validators for multiple input components.

### 6.25.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <h:outputText value="Name:" />

           <h:inputText value="#{userBean.name}" id="name" required="true">

                  <f:validateLength minimum="3" maximum="12"/>

                  <rich:graphValidator event="onblur"/>

           </h:inputText>

    ...

### 6.25.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlCalendar;

    ...

    HtmlgraphValidator mygraphValidator= new HtmlgraphValidator();

    ...

The <rich:graphValidator> component behaves basically the same way as the <rich:beanValidator> The deference between these two components is that in order to validate some input data with a <rich:beanValidator> component, it should be a nested element of an input component, whereas <rich:graphValidator> wraps multiple input components and validates the data received from them.

The following example demonstrate a pattern of how the <rich:graphValidator> can be used.

    ...

    <rich:graphValidator>

           <h:panelGrid columns="3">

                  <h:outputText value="Name:" />

                  <h:inputText value="#{validationBean.name}" id="name">

                         <f:validateLength minimum="2" />

                  </h:inputText>

                  <rich:message for="name" />

                  <h:outputText value="Email:" />

                  <h:inputText value="#{validationBean.email}" id="email" />

                  <rich:message for="email" />

           </h:panelGrid>

    </rich:graphValidator>

    ...

The data validation can be also performed using Hibernate Validator, the same way as it is done with <rich:beanValidator> .

The components's architecture provides an option to bind the component to a managed bean, which is done with the <value> attribute. The attribute ensures that the entered data is valid after the model is updated by revalidating the bean properties.

Please look at the example below.

    ...

    <rich:graphValidator value="#{dayStatistics}">

           <h:outputText value="#{pt.title}" />

                  <rich:inputNumberSpinne minValue="0" maxValue="24" value="#{pt.time}" id="time">

           </rich:inputNumberSpinner>

           <rich:message for="time" />

    </rich:graphValidator>

    ...

### 6.26.3. Creating the Component with a Page Tag

To create the simplest variant of the component on a page use the following syntax:

Example:

    ...

    <h:inputText value="#{validationBean.email}" id="email">

           <rich:beanValidator summary="Invalid email"/>

    </h:inputText>

    ...

### 6.26.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlCalendar;

    ...

    HtmlbeanValidator mybeanValidator= new HtmlbeanValidator();

    ...

#### 6.26.4.1. Details of Usage

Starting from 3.2.2 GA version Rich Faces provides support for model-based constraints defined using Hibernate Validator. Thus it's possible to use Hibernate Validators the same as for Seam based applications.

The <rich:beanValidator> component is defined in the same way as any JSF validator. Look at the example below.

    ...

    <rich:panel>

           <f:facet name="header">

                  <h:outputText value="#{validationBean.progressString}" id="progress"/>

           </f:facet>

           <h:panelGrid columns="3">

                  <h:outputText value="Name:" />

                  <h:inputText value="#{validationBean.name}" id="name">

                         <rich:beanValidator summary="Invalid name"/>

                  </h:inputText>

                  <rich:message for="name" />

                  <h:outputText value="Email:" />

                  <h:inputText value="#{validationBean.email}" id="email">

                         <rich:beanValidator summary="Invalid email"/>

                  </h:inputText>

                  <rich:message for="email" />

                  <f:facet name="footer">

                         <a4j:commandButton value="Submit" action="#{validationBean.success}" reRender="progress"/>

                  </f:facet>

           </h:panelGrid>

    </rich:panel>

    ...

Please play close attention on the bean code that contains the constraints defined with Hibernate annotation which perform validation of the input data.

    package org.richfaces.demo.validation;

    import org.hibernate.validator.Email;

    import org.hibernate.validator.Length;

    import org.hibernate.validator.NotEmpty;

    public class ValidationBean {

        @NotEmpty

        @Length(min=3,max=12)

        private String name;

        @Email

        @NotEmpty

        private String email;

        public ValidationBean() {

        }

        public String getName() {

            return name;

        }

        public void setName(String name) {

            this.name = name;

        }

        public String getEmail() {

            return email;

        }

        public void setEmail(String email) {

            this.email = email;

        }

    }

The following figure shows what happens if validation fails

Figure 6.3. <rich:beanValidator> usage

As you can see from the example that in order to validate the <rich:beanValidator> should be nested into a input JSF or RichFaces component.

The component has the only attribute - "summary" which displays validation messages about validation errors.

## 6.27. < rich:calendar >

### 6.27.1. Description

The <rich:calendar> component is used for creating monthly calendar elements on a page.

### 6.27.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

          <rich:calendar popup="false"/>

    ...

### 6.27.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlCalendar;

    ...

    HtmlCalendar myCalendar = new HtmlCalendar();

    ...

### 6.27.5. Details of Usage

The "popup" attribute defines calendar representation mode on a page. If it's "true" the calendar is represented on a page as an input field and a button. Clicking on the button calls the calendar popup as it's shown on the picture below.

Figure 6.5. Using the "popup" attribute: calendar calls after you click on the button.

Usage "currentDate" attribute isn't available in the popup mode.

The "value" attribute stores selected date currently.

With help of the "currentDate" attribute you can define month and year which will be displayed currently.

The "todayControlMode" attribute defines the mode for "today" control. Possible values are:

- "hidden" - in this mode "Today" button will not be displayed

- "select" - (default) in this state "Today" button activation will scroll the calendar to the current date and it become selected date

- "scroll" - in this mode "Today" activation will simply scroll the calendar to current month without changing selected day.

The <rich:calendar> component can render pages of days in two modes. A mode could be defined with the "mode" attribute with two possible parameters: "`ajax`" and "`client`". Default value is `"client"`.

- `Ajax`

Calendar requests portions of data from Data Model for a page rendering. If "dataModel" attribute has "null" value, data requests are not sent. In this case the "`ajax`" mode is equal to the "`client`".

- `Client`

Calendar loads an initial portion of data in a specified range and use this data to render months. Additional data requests are not sent.

## Note:

"preloadDateRangeBegin" and "preloadDateRangeEnd" attributes were designed only for the "`client`" mode to load some data initially.

"ondataselect" attribute is used to define an event that is triggered before date selection.

"ondateselected" attribute is used to define an event that is triggered after date selection.

For example, to fire some event after date selection you should use <a4j:support> . And it should be bound to "ondateselected" event as it's shown in the example below:

    ...

        <rich:calendar id="date" value="#{bean.dateTest}">

            <a4j:support event="ondateselected" reRender="mainTable"/>

        </rich:calendar>

    ...

"ondataselect" could be used for possibility of date selection canceling. See an example below:

    ...

        <rich:calendar id="date" value="#{bean.dateTest}" ondateselect="if (!confirm('Are you sure to change date?')){return false;}"/>

        ...

"oncurrentdataselected" event is fired when the "next/previous month" or "next/previous year" button is pressed, and the value is applied.

"oncurrentdataselect" event is fired when the "next/previous month" or "next/previous year" button is pressed, but the value is not applied yet (you can change the logic of applying the value). Also this event could be used for possibility of "next/previous month" or "next/previous year" selection canceling. See an example below:

Example:

    ...

    <rich:calendar id="date" value="#{bean.dateTest}" oncurrentdateselect="if (!confirm('Are you sure to change month(year)?')){return false;}"

    oncurrentdateselected="alert('month(year) select:'+event.rich.date.toString());"/>

     ...

How to use these attributes see also on the RichFaces Users Forum.

Information about the "process" attribute usage you can find here.

There are three button-related attributes:

- "buttonLabel" defines a label for the button. If the attribute is set "buttonIcon" and "buttonIconDisabled" are ignored

- "buttonIcon" defines an icon for the button

- "buttonIconDisabled" defines an icon for the disabled state of the button

The "direction" and "jointPoint" attributes are used for defining aspects of calendar appearance.

The possible values for the "direction" are:

- "top-left" - a calendar drops to the top and left

- "top-right" - a calendar drops to the top and right

- "bottom-left" - a calendar drops to the bottom and left

- "bottom-right" - a calendar drops to the bottom and right

- "auto" - smart positioning activation

By default, the "direction" attribute is set to "bottom-right".

The possible values for the "jointPoint" are:

- "top-left" - a calendar docked to the top-left point of the button element

- "top-right" - a calendar docked to the top-right point of the button element

- "bottom-left" - a calendar docked to the bottom-left point of the button element

- "bottom-right" - a calendar docked to the bottom-right point of the button element

- "auto" - smart positioning activation

By default, the "jointPoint" attribute is set to "bottom-left".

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"`, {2} for `"ShortConverter.SHORT"`.

The "defaultTime" attribute to set the default time value for the current date in two cases:

- If time is not set

- If another date is selected and the value of the "resetTimeOnDateSelect" attribute is set to "true"

The "enableManualInput" attribute enables/disables input field, so when `enableManualInput = "false"` , user can only pick the date manually and has no possibility to type in the date (default value is "false").

The <rich:calendar> component allows to use "header" , "footer" , "optionalHeader" , "optionalFooter" facets. The following elements are available in these facets: `{currentMonthControl}`, `{nextMonthControl}`, `{nextYearControl}`, `{previousYearControl}`, `{previousMonthControl}`, `{todayControl}`, `{selectedDateControl}`. These elements could be used for labels output.

Also you can use "weekNumber" facet with available `{weekNumber}`, `{elementId}` elements and "weekDay" facet with `{weekDayLabel}`, `{weekDayLabelShort}`, `{weekDayNumber}`, `{isWeekend}`, `{elementId}` elements. `{weekNumber}`, `{weekDayLabel}`, `{weekDayLabelShort}`, `{weekDayNumber}` elements could be used for labels output, `{isWeekend}`, `{elementId}` - for additional processing in JavaScript code.

These elements are shown on the picture below.

Figure 6.6. Available elements

Simple example of usage is placed below.

Example:

    ...

    <!-- Styles for cells -->

    <style>

        .width100{

            width:100%;

        }

        .talign{

            text-align:center;

        }

    </style>

     ...

    ...

    <rich:calendar id="myCalendar" popup="true" locale="#{calendarBean.locale}" value="#{bean.date}"

                                preloadRangeBegin="#{bean.date}" preloadRangeEnd="#{bean.date}" cellWidth="40px" cellHeight="40px">

    <!-- Customization with usage of facets and accessible elements -->

        <f:facet name="header">

            <h:panelGrid columns="2" width="100%" columnClasses="width100, fake">

                <h:outputText value="{selectedDateControl}" />

                <h:outputText value="{todayControl}"  style="font-weight:bold; text-align:left"/>

            </h:panelGrid>

        </f:facet>

        <f:facet name="weekDay">

            <h:panelGroup style="width:60px; overflow:hidden;" layout="block">

                <h:outputText value="{weekDayLabelShort}"/>

            </h:panelGroup>

        </f:facet>

        <f:facet name="weekNumber">

             <h:panelGroup>

                <h:outputText value="{weekNumber}" style="color:red"/>

            </h:panelGroup>

         </f:facet>

         <f:facet name="footer">

            <h:panelGrid columns="3" width="100%" columnClasses="fake, width100 talign">

                <h:outputText value="{previousMonthControl}" style="font-weight:bold;"/>

                <h:outputText value="{currentMonthControl}" style="font-weight:bold;"/>

                <h:outputText value="{nextMonthControl}" style="font-weight:bold;"/>

            </h:panelGrid>

        </f:facet>

        <h:outputText value="{day}"></h:outputText>

    </rich:calendar>

    ...

This is a result:

Figure 6.7. Facets usage

As it's shown on the picture above `{selectedDateControl}`, `{todayControl}` elements are placed in the "header" facet, `{previousMonthControl}`, `{currentMonthControl}`, `{nextMonthControl}` - in the "footer" facet, `{weekDayLabelShort}` - in the "weekDay" facet, `{nextYearControl}`, `{previousYearControl}` are absent. Numbers of weeks are red colored.

It is possible to show and manage date. Except scrolling controls you can use quick month and year selection feature. It's necessary to click on its field, i.e. current month control, and choose required month and year.

Figure 6.8. Quick month and year selection

Also the <rich:calendar> component allows to show and manage time. It's necessary to define time in a pattern (for example, it could be defined as "`d/M/yy HH:mm`"). Then after you choose some data in the calendar, it becomes possible to manage time for this date. For time editing it's necessary to click on its field (see a picture below). To clean the field click on the "Clean".

Figure 6.9. Timing

It's possible to handle events for calendar from JavaScript code. A simplest example of usage JavaScript API is placed below:

Example:

    ...

             <rich:calendar value="#{calendarBean.selectedDate}" id="calendarID"

                            locale="#{calendarBean.locale}"

                            popup="#{calendarBean.popup}"

                            datePattern="#{calendarBean.pattern}"

                            showApplyButton="#{calendarBean.showApply}" style="width:200px"/>

         <a4j:commandLink onclick="$('formID:calendarID').component.doExpand(event)" value="Expand"/>

    ...

Also the discussion about this problem can be found on the RichFaces Users Forum.

The <rich:calendar> component provides the possibility to use a special Data Model to define data for element rendering. Data Model includes two major interfaces:

- `CalendarDataModel`

- `CalendarDataModelItem`

`CalendarDataModel` provides the following function:

- `CalendarDataModelItem[] getData(Date[])`;

This method is called when it's necessary to represent the next block of `CalendarDataItems`. It happens during navigation to the next (previous) month or in any other case when calendar renders. This method is called in "Ajax" mode when the calendar renders a new page.

`CalendarDataModelItem` provides the following function:

- Date `getDate()` - returns date from the item. Default implementation returns date.

- Boolean `isEnabled()` - returns "true" if date is "selectable" on the calendar. Default implementation returns "true".

- String `getStyleClass()` - returns string appended to the style class for the date span. For example it could be "relevant holyday". It means that the class could be defined like the "rich-cal-day-relevant-holyday" one. Default implementation returns empty string.

- Object `getData()` - returns any additional payload that must be JSON-serializable object. It could be used in the custom date representation on the calendar (inside the custom facet).

The <rich:calendar> component provides the possibility to use internationalization method to redefine and localize the labels. You could use application resource bundle and define `RICH_CALENDAR_APPLY_LABEL`, `RICH_CALENDAR_TODAY_LABEL`, `RICH_CALENDAR_CLOSE_LABEL`, `RICH_CALENDAR_OK_LABEL`, `RICH_CALENDAR_CLEAN_LABEL`, `RICH_CALENDAR_CANCEL_LABEL` there.

You could also pack `org.richfaces.renderkit.calendar` resource bundle with your JARs defining the same properties.

## Note:

Only for Internet Explorer 6 and later. To make <rich:calendar> inside <rich:modalPanel> rendered properly, enable the standards-compliant mode. Explore !DOCTYPE reference at MSDN to find out how to do this.

### 6.27.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:calendar> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:calendar> component

In order to redefine styles for all <rich:calendar> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-calendar-today {

        background-color: #FF0000;

    }

    ...

This is a result:

Figure 6.14. Redefinition styles with predefined classes

In the example an active cell background color was changed.

Also it's possible to change styles of particular <rich:calendar> component. In this case you should create own style classes and use them in corresponding <rich:calendar> styleClass attributes. An example is placed below:

Example:

    ...

    .myFontClass{

        font-style: italic;

    }

    ...

The "inputClass" attribute for <rich:calendar> is defined as it's shown in the example below:

Example:

    <rich:calendar ... inputClass="myFontClass"/>

This is a result:

Figure 6.15. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for output text was changed.

### 6.28.5. Details of Usage

The <rich:comboBox> is a simplified suggestion box component, that provides input with client side suggestions. The component could be in two states:

- Default - only input and button is shown

- Input, button and a popup list of suggestions attached to input is shown

There are two ways to get values for the popup list of suggestions:

- Using the "suggestionValues" attribute, that defines the suggestion collection

  Example:

      ...

      <rich:comboBox value="#{bean.state}" suggestionValues="#{bean.suggestions}" />

      ...

- Using the <f:selectItem /> or <f:selectItems /> facets which considers only "value" attribute.

  Example:

      ...

      <rich:comboBox value="#{bean.state}" valueChangeListener="#{bean.selectionChanged}">

              <f:selectItems  value="#{bean.selectItems}"/>

              <f:selectItem itemValue="Oregon"/>

              <f:selectItem itemValue="Pennsylvania"/>

              <f:selectItem itemValue="Rhode Island"/>

              <f:selectItem itemValue="South Carolina"/>

      </rich:comboBox>

      ...

Popup list content loads at page render time. No additional requests could be performed on the popup calling.

The "value" attribute stores value from input after submit.

The "directInputSuggestions" attribute defines, how the first value from the suggested one appears in an input field. If it's "true" the first value appears with the suggested part highlighted.

Example:

    ...

    <rich:comboBox value="#{bean.state}" suggestionValues="#{bean.suggestions}" directInputSuggestions="true" />

    ...

This is a result:

Figure 6.17. <rich:comboBox> with "directInputSuggestions" attribute.

The "selectFirstOnUpdate" attribute defines if the first value from suggested is selected in a popup list. If it's "false" nothing is selected in the list before a user hovers some item with the mouse.

Example:

    ...

    <rich:comboBox value="#{bean.state}" suggestionValues="#{bean.suggestions}" selectFirstOnUpdate="false" />

    ...

This is a result:

Figure 6.18. <rich:comboBox> with "selectFirstOnUpdate" attribute.

The "defaultLabel" attribute defines the default label of the input element. Simple example is placed below.

Example:

    ...

    <rich:comboBox value="#{bean.state}" suggestionValues="#{bean.suggestions}" defaultLabel="Select a city..." />

    ...

This is a result:

Figure 6.19. <rich:comboBox> with "defaultLabel" attribute.

With the help of the "disabled" attribute you can disable the whole <rich:comboBox> component. See the following example.

Example:

    ...

    <rich:comboBox value="#{bean.state}" suggestionValues="#{bean.suggestions}" defaultLabel="Select a city..." disabled="true" />

    ...

This is a result:

Figure 6.20. <rich:comboBox> with "disabled" attribute.

The "enableManualInput" attribute enables/disables input field, so when `enableManualInput = "false"` , user can only pick the value manually and has no possibility to type in the value (default value is "false").

The <rich:comboBox> component provides to use specific event attributes:

- "onlistcall" which is fired before the list opening and gives you a possibility to cancel list popup/update

- "onselect" which gives you a possibility to send AJAX request when item is selected

The <rich:comboBox> component allows to use sizes attributes:

- "listWidth" and "listHeight" attributes specify popup list sizes with values in pixels

- "width" attribute customizes the size of input element with values in pixels.

### 6.28.6. JavaScript API

Table 6.84. JavaScript API

Function | Description
--- | ---
showList() | Shows the popup list
hideList() | Hides the popup list
enable() | Enables the control for input
disable() | Disables the control for input

### 6.28.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:comboBox> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:comboBox> component

rich-combobox-shadow-bl | Defines styles for a bottom-left element of a shadow
rich-combobox-shadow-br | Defines styles for a bottom-right element of a shadow

In order to redefine styles for all <rich:comboBox> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-combobox-list-decoration{

            background-color:#ecf4fe;

    }

    ...

This is a result:

Figure 6.23. Redefinition styles with predefined classes

In the example background color for popup list was changed.

Also it's possible to change styles of particular <rich:comboBox> component. In this case you should create own style classes and use them in corresponding <rich:comboBox> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            font-weight:bold;

    }

    ...

The "listClass" attribute for <rich:comboBox> is defined as it's shown in the example below:

Example:

    <rich:comboBox ... listClass="myClass"/>

This is a result:

Figure 6.24. Redefinition styles with own classes and "styleClass" attributes

As it could be seen on the picture above, the font weight for items was changed.

## 6.29. < rich:componentControl >

### 6.29.1. Description

The <rich:componentControl> allows to call JavaScript API functions on components after defined events.

### 6.29.2. Key Features

- Management of components JavaScript API

- Customizable initialization variants

- Customizable activation events

- Possibility to pass parameters to the target component

Table 6.105. rich : componentControl attributes

Attribute Name | Description
--- | ---
attachTiming | Defines the page loading phase when componentControl is attached to another component. Default value is "onavailable"
attachTo | Client identifier of the component or id of the existing DOM element that is a source for given event. If attachTo is defined, the event is attached on the client according to the attachTiming attribute. If attachTo is not defined, the event is attached on the server to the closest in the component tree parent component.
binding | The attribute takes a value-binding expression for a component property of a backing bean
disableDefault | Disable default action for target event ( append "return false;" to JavaScript )
event | The Event that is used to trigger the operation on the target component
for | Client identifier of the target component.
id | Every component may have a unique id that is automatically created if omitted
name | The optional name of the function that might be used to trigger the operation on the target component
operation | The function of JavaScript API that will be invoked. The API method is attached to the 'component' property of the root DOM element that represents the target component. The function has two parameters - event and params. See: 'params' attribute for details.
params | The set of parameters passed to the function of Javascript API that will be invoked. The JSON syntax is used to define the parameters, but without open and closed curve bracket. As an alternative, the set of f:param can be used to define the parameters passed to the API function. If both way are used to define the parameters, both set are concatenated. if names are equals, the f:param has a priority.
rendered | If "false", this component is not rendered

Table 6.106. Component identification parameters

Name | Value
--- | ---
component-type | org.richfaces.ComponentControl
component-class | org.richfaces.component.html.HtmlComponentControl
component-family | org.richfaces.ComponentControl
renderer-type | org.richfaces.ComponentControlRenderer
tag-class | org.richfaces.taglib.ComponentControlTag

### 6.29.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:componentControl attachTo="doExpandCalendarID" for="ccCalendarID" event="onclick" operation="Expand" />

    ...

### 6.29.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlComponentControl;

    ...

    HtmlComponentControl myComponentControl = new HtmlComponentControl();

    ...

### 6.29.5. Details of Usage

<rich:componentControl> is a command component, that allows to call JavaScript API function on some defined event. Look at the example:

    ...

    <rich:componentControl attachTo="doExpandCalendarID" event="onclick" for="ccCalendarID" operation="Expand"/>

    ...

In other words it means "clicking on the component with ID 'doExpandCalendarID', expands the component with ID 'ccCalendarID'". It can be said, that <rich:componentControl> connects two components with the help of JavaScript API function.

Component ID, to wich the event, that invokes JavaScript API function is applied, is defined with "attachTo" attribute (see the exapmle above). If "attachTo" attribute is not defined, the component will be attached to the parent component.

Example:

    ...

    <h:commandButton value="Show Modal Panel">

        <rich:componentControl for="ccModalPanelID" event="onclick" operation="show"/> <!--attached to the commandButton-->

    </h:commandButton>

    ...

On the result page the component is rendered to JavaScript code. This means, that it is possible to invoke the <rich:componentControl> handler operation as usual JavaScript function. This function is called by name, specified in the component "name" attribute. The definition of "name" attribute is shown on the example below:

    ...

    <rich:componentControl name="func" event="onRowClick" for="menu" operation="show" />

    ...

The generated JavaScript function will look as shown below:

    function func (event) {

    }

An important <rich:componentControl> feature, is that it allows transferring parameters, with the help of special attribute "params" .

Example:

    ...

    <rich:componentControl name="func" event="onRowClick" for="menu" operation="show" params=#{car.model}"/>

    ...

The alternative way for parameters transferring uses <f:param> attribute. As the code above, the following code will represent the same functionality.

Example:

    ...

    <rich:componentControl event="onRowClick" for="menu" operation="show">

                    <f:param value="#{car.model}" name="model"/>

    </rich:componentControl>

    ...

With the help of the "attachTiming" attribute you can define the page loading phase when <rich:componentControl> is attached to source component. Possible values are:

- "immediate" - attached during execution of <rich:componentControl> script

- "onavailable" - attached after the target component is initialized

- "onload" - attached after the page is loaded

<rich:componentControl> interacts with such components as: <rich:contextMenu> , <rich:toolTip> , <rich:modalPanel > , <rich:listShuttle> , <rich:orderingList> , <rich:calendar>

In order to use <rich:componentControl> with another component you should place the id of this component into "for" attribute field. All operations with defined component you can find in the JavaScript API section of defined component.

Example:

    ...

    <f:view>

        <h:form>

            <br />

            <rich:toolTip id="toolTipFor" followMouse="false" direction="top-right" mode="ajax" value="This is button" horizontalOffset="5" verticalOffset="5" layout="block" />

        </h:form>

        <h:commandButton id="ButtonID" value="Button">

            <rich:componentControl for="toolTipFor" attachTo="ButtonID" operation="show" event="onclick"/>

        </h:commandButton>

    </f:view>

    ...

This is a result:

Figure 6.25. <rich:toolTip> shows with the help of <rich:componentControl> .

As it could be seen in the picture above, the <rich:toolTip> shows after you click the button.

### 6.29.6. Look-and-Feel Customization

<rich:componentControl> has no skin parameters and custom style classes, as the component isn't visual.

### 6.29.7. Relevant Resources Links

Here you can see an example of <rich:componentControl> usage and sources for the given example.

Here you can found some additional information about <f:param> component.

## 6.30. < rich:contextMenu >

### 6.30.1. Description

The <rich:contextMenu> component is used for creation multileveled context menus that are activated after a user defines an event ( "onmouseover" , "onclick" , etc.) on any element on the page.

Figure 6.26. <rich:contextMenu> component

### 6.30.2. Key Features

- Highly customizable look and feel

- "oncontextmenu" event support

- Disablement support

- Pop-up appearance event customization

- Usage of shared instance of a menu on a page

Table 6.107. rich : contextMenu attributes

Attribute Name | Description
--- | ---

### 6.30.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:contextMenu event="oncontextmenu" attached="true">

    ...

### 6.30.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.ContextMenu;

    ...

    html.ContextMenu myContextMenu = new html.ContextMenu();

    ...

### 6.30.5. Details of Usage

<rich:contextMenu> is a support-like component. Context menu itself is an invisible panel that appears after a particular client side event ( "onmouseover" , "onclick" , etc.) occurred on a parent component. The event is defined with an "event" attribute. The component uses "oncontextmenu" event by default to call a context menu by clicking on the right mouse button.

<rich:menuGroup> , <rich:menuItem> and <rich:menuSeparator> components are used as nested elements for <rich:contextMenu> in the same way as for <rich:dropDownMenu> .

If "attached" value is "true" (default value), component is attached to the parent component or to the component, which "id" is specified in the "attachTo" attribute. An example is placed below.

Example:

    ...

            <rich:contextMenu event="oncontextmenu" attachTo="pic1" submitMode="none">

                <rich:menuItem value="Zoom In" onclick="enlarge();" id="zin"/>

                <rich:menuItem value="Zoom Out" onclick="decrease();" id="zout"/>

            </rich:contextMenu>

            <h:panelGrid columns="1" columnClasses="cent">

                    <h:panelGroup id="picture">

                            <h:graphicImage value="/richfaces/jQuery/images/pic1.png" id="pic"/>

                    </h:panelGroup>

            </h:panelGrid>

            <h:panelGrid columns="1" columnClasses="cent">

                    <h:panelGroup id="picture1">

                            <h:graphicImage value="/richfaces/jQuery/images/pic2.png" id="pic1"/>

                    </h:panelGroup>

            </h:panelGrid>

    ...

The `"enlarge()"` and `"decrease()"` functions definition is placed below.

    ...

            <script type="text/javascript">

                    function enlarge(){

                            document.getElementById('pic').width=document.getElementById('pic').width*1.1;

                            document.getElementById('pic').height=document.getElementById('pic').height*1.1;

                    }

                    function decrease(){

                            document.getElementById('pic').width=document.getElementById('pic').width*0.9;

                            document.getElementById('pic').height=document.getElementById('pic').height*0.9;

                    }

            </script>

    ...

In the example a picture zooming possibility with <rich:contextMenu> component usage was shown. The picture is placed on the <h:panelGroup> component. The <rich:contextMenu> component is not nested to <h:panelGroup> and has a value of the "attachTo" attribute defined as `"pic1"`. Thus, the context menu is attached to the component, which "id" is `"pic1"`. The context menu has two items to zoom in (zoom out) a picture by "onclick" event. For earch item corresponding JavaScript function is defined to provide necessary action as a result of the clicking on it. For the menu is defined an "oncontextmenu" event to call the context menu on a right click mouse event.

In the example the context menu is defined for the parent <h:panelGroup> component with a value of "id" attribute equal to "`picture`" You should be careful with such definition, because a client context menu is looked for a DOM element with a client Id of a parent component on a server. If a parent component doesn't encode an Id on a client, it can't be found by the <rich:contextMenu> and it's attached to its closest parent in a DOM tree.

If the "attached" attribute has "false" value, component activates via JavaScript API with assistance of <rich:componentControl> . An example is placed below.

Example:

    ...

            <h:form id="form">

                    <rich:contextMenu attached="false" id="menu" submitMode="ajax">

                            <rich:menuItem ajaxSingle="true">

                                    <b>{car} {model}</b> details

                                    <a4j:actionParam name="det" assignTo="#{ddmenu.current}" value="{car} {model} details"/>

                            </rich:menuItem>

                            <rich:menuGroup value="Actions">

                                    <rich:menuItem ajaxSingle="true">

                                            Put <b>{car} {model}</b> To Basket

                                            <a4j:actionParam name="bask" assignTo="#{ddmenu.current}" value="Put {car} {model} To Basket"/>

                                    </rich:menuItem>

                                    <rich:menuItem value="Read Comments" ajaxSingle="true">

                                            <a4j:actionParam name="bask" assignTo="#{ddmenu.current}" value="Read Comments"/>

                                    </rich:menuItem>

                                    <rich:menuItem ajaxSingle="true">

                                            Go to <b>{car}</b> site

                                            <a4j:actionParam name="bask" assignTo="#{ddmenu.current}" value="Go to {car} site"/>

                                    </rich:menuItem>

                    </h:panelGrid>

            </h:form>

     ...

This is a result:

Figure 6.27. The "attached" attribute usage

In the example the context menu is activated (by clicking on the left mouse button) on the table via JavaScript API with assistance of <rich:componentControl> . The attribute "for" contains a value of the <rich:contextMenu> Id. For menu appearance Java Script API function `"show()"` is used. It is defined with "operation" attribute for the <rich:componentControl> component. Context menu is recreated after the every call on a client and new {car} and {model} values are inserted in it. In the example for a menu customization macrosubstitutions were used.

The <rich:contextMenu> component can be defined once on a page and can be used as shared for different components (this is the main difference from the <rich:dropDownMenu> component). It's necessary to define it once on a page (as it was shown in the example above) and activate it on required components via JavaScript API with assistance of <rich:componentControl> .

The <rich:contextMenu> "submitMode" attribute can be set to three possible parameters:

- `Server` (default)

Regular form submition request is used

- `Ajax`

Ajax submission is used for switching

- `None`

The "action" and "actionListener" item's attributes are ignored. Menu items don't fire any submits themselves. The behavior is fully defined by the components nested inside items.

## Note:

As the <rich:contextMenu> component doesn't provide its own form, use it between <h:form> and </h:form> tags.

## Note:

When using <rich:contextMenu> component with <h:outputText> JSF component, specify id for <h:outputText> or move <rich:contextMenu> out from <h:outputText> to provide component's correct work.

### 6.30.6. JavaScript API

Table 6.109. JavaScript API

Function | Description | Apply to
--- | --- | ---
hide() | Hides component or group | Component, group
show(event, context) | Shows component or group | Component, group

### 6.30.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:contextMenu> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:contextMenu> component

### 6.30.8. Skin Parameters Redefinition

Table 6.110. Skin parameters redefinition for a border

Skin parameters | CSS properties

panelBorderColor | border-color
additionalBackgroundColor | background-color

Skin parameters | CSS properties
--- | ---
additionalBackgroundColor | border-top-color
additionalBackgroundColor | border-left-color

### 6.30.9. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.28. Style classes

Table 6.112. Classes names that define the contextMenu element

Class name | Description
--- | ---
rich-menu-list-border | Defines styles for borders
rich-menu-list-bg | Defines styles for a general background list
rich-menu-list-strut | Defines styles for a wrapper <div> element for a strut of a popup list

In order to redefine styles for all <rich:contextMenu> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-menu-item{

            font-style:italic;

    }

    ...

This is a result:

Figure 6.29. Redefinition styles with predefined classes

In the example the font style for row items was changed.

Also it's possible to change styles of particular <rich:contextMenu> component. In this case you should create own style classes and use them in corresponding <rich:contextMenu> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            font-weight:bold;

    }

    ...

The "rowClasses" attribute for <h:panelGrid> is defined as it's shown in the example below:

Example:

    <h:panelGrid ... rowClasses="myClass"/>

This is a result:

Figure 6.30. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font weight for row items was changed.

### 6.31.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

        <rich:dataFilterSlider sliderListener="#{mybean.doSlide}" startRange="0"

                                                endRange="50000" increment="10000" handleValue="1" />

    ...

### 6.31.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDataFilterSlider;

    ...

    HtmlDataFilterSlider mySlider = new HtmlDataFilterSlider();

    ...

### 6.31.5. Details of Usage

The dataFilterSlider component is bound to some UIData component using a "for" attribute and filters data in a table.

Example:

    ...

        <rich:dataFilterSlider sliderListener="#{mybean.doSlide}"

                            startRange="0"

                            endRange="50000"

                            increment="10000"

                            handleValue="1"

                            for="carIndex"

                            forValRef="inventoryList.carInventory"

                            filterBy="getMileage"

        />

    ...

        <h:dataTable id="carIndex">

            ...

        </h:dataTable>

    ...

In this example other two attributes are used for filtering:

- "forValRef" is a string which is used in a value attribute of the target UIData component. It's designed for resetting the UIData component back to the original list provided by a backing bean.

- "filterBy" is a getter of an object member that is to be compared to a slider value. It's a value that is used in results filtering.

"handleValue" is an attribute for keeping the current handler position on the dataFilterSlider component. Based on the current value, appropriate values obtained from a getter method defined in "filterBy" are filtered.

One more important attribute is a "storeResults" one that allows the dataFilterSlider component to keep UIData target object in session.

If it's necessary the component submits a form on event of a handler state changing, use the "onSlide" attribute ( "onChange" is its alias). When the attribute `definition = "true"`, submission on this event is defined.

Information about the "process" attribute usage you can find here.

### 6.31.6. Look-and-Feel Customization

The <rich:dataFilterSlider> component has no skin parameters and special style classes , as it consists of one element generated with a your method on the server. To define some style properties such as an indent or a border, it's possible to use "style" and "styleClass" attributes on the component.

### 6.31.7. Relevant Resources Links

Here you can see the example of <rich:dataFilterSlider> usage and sources for the given example.

### 6.32.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

        <h:dataTable id="table">

            ...

        </h:dataTable>

        ...

        <rich:datascroller for="table"/>

    ...

### 6.32.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDatascroller;

    ...

    HtmlDatascroller myScroll = new HtmlDatascroller();

    ...

### 6.32.5. Details of Usage

The <rich:datascroller> component provides table scrolling functionalitity the same as TOMAHAWK scroller but with Ajax requests usage.

The component should be placed into footer of the parent table or be bound to it with the "for" attribute. Note, that "for" is evaluated on view build, not on view render, that is why it will ignore JSTL tags.

The table should also have the defined "rows" attribute limiting the quantity of inputted table rows.

The scroller could limit the maximum quantity of rendered links on the table pages with the help of the "maxPages" attribute.

Component provides two controllers groups for switching:

- Page numbers for switching onto a particular page

- The controls of fast switching: "first", "last", "next", "previous", "fastforward", "fastrewind"

The controls of fast switching are created adding the facets component with the corresponding name:

Example:

     ...

        <rich:datascroller for="table" maxPages="10">

            <f:facet name="first">

                <h:outputText value="First"/>

            </f:facet>

            <f:facet name="last">

                <h:outputText value="Last"/>

            </f:facet>

        </rich:datascroller>

    ...

Figure 6.33. <rich:datascroller> controls of fast switching

The screenshot shows one controller from each group.

There are also facets used to create the disabled states: `"first_disabled",` `"last_disabled",` `"next_disabled",` `"previous_disabled",` `"fastforward_disabled",` `"fastrewind_disabled"`.

For the `"fastforward"/"fastrewind"` controls customization the additional "fastStep" attribute is used. The attribute indicates pages quantity to switch onto when fast scrolling is used.

The "page" is a value-binding attribute used to define and save current page number. The example is placed below.

Example:

    ...

    <h:form id="myForm">

        <rich:dataTable id="carList" rows="7" value="#{dataTableScrollerBean.allCars}" var="category">

            <f:facet name="header">

                <rich:columnGroup>

                    <h:column>

                        <h:outputText value="Make" />

                    </h:column>

                    <h:column>

                        <h:outputText value="Model" />

                    </h:column>

                    <h:column>

                        <h:outputText value="Price" />

                    </h:column>

                </rich:columnGroup>

            </f:facet>

            <h:column>

                <h:outputText value="#{category.make}" />

            </h:column>

            <h:column>

                <h:outputText value="#{category.model}" />

            </h:column>

            <h:column>

                <h:outputText value="#{category.price}" />

            </h:column>

        </rich:dataTable>

        <rich:datascroller id="sc2" for="carList" reRender="sc1" maxPages="7" page="#{dataTableScrollerBean.scrollerPage}" />

        <h:panelGrid>

            <h:panelGroup>

                <h:outputText value="Set current page number:" />

                <h:inputText value="#{dataTableScrollerBean.scrollerPage}" id="sc1" size="1"/>

                <h:commandButton value="Set" />

            </h:panelGroup>

        </h:panelGrid>

    </h:form>

    ...

In the example above you can enter the page number you want and set it by clicking on the <h:commandButton> . By the way, if you use <rich:datascroller> page links the input field rerenders and current page number changes.

This is a result:

Figure 6.34. The "page" attribute usage

The "pageIndexVar" and "pagesVar" attributes define a request scope variables and provide an ability to show the current page and the number of pages in the <rich:datascroller> .

These attributes are used for definition the names of variables, that is used in the facet with name "pages" . An example can be found below:

Example:

    ...

    <h:form>

        <rich:dataTable value="#{capitalsBean.capitals}" var="cap" rows="5">

            <rich:column>

                <h:outputText value="#{cap.name}" />

            </rich:column>

            <f:facet name="footer">

                <rich:datascroller pageIndexVar="pageIndex" pagesVar="pages">

                    <f:facet name="pages">

                        <h:outputText value="#{pageIndex} / #{pages}" />

                    </f:facet>

                </rich:datascroller>

            </f:facet>

        </rich:dataTable>

    </h:form>

    ...

It's possible to insert optional separators between controls. For this purpose use a "controlSeparator" facet. An example is placed below.

     ...

          <f:facet name="controlSeparator">

                <h:graphicImage value="/image/sep.png"/>

          </f:facet>

    ...

Starting from 3.2.1 of RichFaces multiple <rich:datascroller> instances behavior and page bindings are corrected. Incorrect page after model changes handling is added. Phase Listener called before RenderResponce scans the page for the <rich:datascroller> and performs the following operations:

- Checks if the <rich:datascroller> is rendered. (If the checking generates an exception, the <rich:datascroller> is considered to be not rendered )

- If the <rich:datascroller> is rendered - the table to which the <rich:datascroller> is attached gets the value of the page attribute of <rich:datascroller> .

Information about the "process" attribute usage you can find here.

## Note:

Make sure, that all <rich:datascroller> components, defined for a table, have same values for "pages" attributes. The page, specified in the last "page" , will be rendered in browser.

### 6.32.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:datascroller> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:datascroller> component

### 6.32.7. Skin Parameters Redefinition

### 6.32.8. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.35. Style classes

Table 6.121. Classes names that define a component appearance

Class name | Description
--- | ---
rich-datascr | Defines styles for a wrapper <div> element of a datascroller
rich-dtascroller-table | Defines styles for a wrapper table element of a datascroller
rich-datascr-button | Defines styles for a button
rich-datascr-ctrls-separator | Defines styles for a separator between buttons

Table 6.122. Classes names that define a buttons appearance

Class name | Description
--- | ---
rich-datascr-act | Defines styles for an active button
rich-datascr-inact | Defines styles for an inactive button
rich-datascr-button-dsbld | Defines styles for a disabled button

In order to redefine styles for all <rich:datascroller> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above) and define necessary properties in them. An example is placed below:

Example:

    ...

    .rich-datascr-button{

        color: #CD6600;

    }

    ...

This is a result:

Figure 6.36. Redefinition styles with predefined classes

In the example an input text font style was changed.

Also it's possible to change styles of particular <rich:datascroller> component. In this case you should create own style classes and use them in corresponding <rich:datascroller> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        background-color: #C6E2FF;

    }

    ...

The "styleClass" attribute for <rich:datascroller> is defined as it's shown in the example below:

Example:

    <rich:datascroller ... selectedStyleClass="myClass"/>

This is a result:

Figure 6.37. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, background color of the selected cell on scroller was changed.

### 6.33.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:dataTable value="#{capitalsBean.capitals}" var="cap">

            <rich:columns value="#{capitalsBean.labels}" var="col" index="index">

                    <h:outputText value="#{cap[index]}" />

            </rich:columns>

    </rich:dataTable>

    ...

### 6.33.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlColumns;

    ...

    HtmlColumns myColumns = new HtmlColumns();

    ...

### 6.33.5. Details of Usage

The <rich:columns> component gets a list from data model and outputs corresponding set of columns inside <rich:dataTable> on a page. It is possible to use "header" and "footer" facets with <rich:columns> component.

The "value" and "var" attributes are used to access the values of collection.

The simple example is placed below.

Example:

    ...

    <rich:dataTable value="#{capitalsBean.capitals}" var="cap">

            <rich:columns value="#{capitalsBean.labels}" var="col" index="index">

                    <f:facet name="header">

                            <h:outputText value="#{col.text}" />

                    </f:facet>

             <h:outputText value="#{cap[index]}" />

             <f:facet name="footer">

                     <h:outputText value="#{col.text}" />

             </f:facet>

            </rich:columns>

    </rich:dataTable>

    ...

The "columns" attribute defines the count of columns.

The "rows" attribute defines the number of rows to be displayed. If the value of this attribute is zero, all remaining rows in the table are displayed on a page.

The "begin" attribute contains the first iteration item. Note, that iteration begins from zero.

The "end" attribute contains the last iteration item.

With the help of the attributes described below you can customize the output, i.e. define which columns and how many rows appear on a page.

Example:

    ...

    <rich:dataTable value="#{capitalsBean.capitals}" var="cap">

            <rich:columns value="#{capitalsBean.labels}" var="col" index="index" rows="0" columns="3" begin="1" end="2">

                    <f:facet name="header">

                            <h:outputText value="#{col.text}" />

                    </f:facet>

                    <h:outputText value="#{cap[index]}" />

            </rich:columns>

    </rich:dataTable>

    ...

In the example below, columns from first to second and all rows are shown in the <rich:dataTable> .

The result is:

Figure 6.39. Generated <rich:columns> with columns from first to second and all rows

The <rich:columns> component does not prevent to use <rich:column> . In the following example one column renders in any way and another columns could be picked from the model.

Example:

    ...

    <rich:dataTable value="#{rowBean.rows}" var="row">

            <rich:column>

                    <h:outputText value ="#{row.columnValue}"/>

            </rich:column>

            <rich:columns value="#{colBean.columns}" var="col">

                    <f:facet name="header">

                            <h:outputText value="#{col.header}"/>

                    </f:facet>

                    <h:outputText value="#{row.columnValue}"/>

                    <f:facet name="footer">

                            <h:outputText value="#{col.footer}"/>

                    </f:facet>

            </rich:columns>

    </rich:dataTable>

    ...

In order to group columns with text information into one row, use the "colspan" attribute, which is similar to an HTML one. In the following example the third column contains 3 columns. In addition, it's necessary to specify that the next column begins from the first row with the help of the `breakBefore = "true"` .

Example:

    ...

    <rich:dataTable value="#{columns.data1}" var="data">

            <rich:column>

                    <h:outputText value="#{column.Item1}" />

            </rich:column>

            <rich:column>

                    <h:outputText value="#{column.Item2}" />

            </rich:column>

            <rich:column>

                    <h:outputText value="#{column.Item3}" />

            </rich:column>

            <rich:columns columns="3" colspan="3" breakBefore="true">

                    <h:outputText value="#{data.str0}" />

            </rich:columns>

    </rich:dataTable>

    ...

The same way is used for columns grouping with the "rowspan" attribute that is similar to an HTML. The only thing to add in the example is an instruction to move onto the next row for each next after the second column.

Example:

    ...

    <rich:dataTable value="#{columns.data1}" var="data">

            <rich:columns columns="2" rowspan="3">

                    <h:outputText value="#{data.str0}" />

            </rich:columns>

            <rich:column>

                    <h:outputText value="#{column.Item1}" />

            </rich:column>

            <rich:column  breakBefore="true">

                    <h:outputText value="#{column.Item2}" />

            </rich:column>

            <rich:column  breakBefore="true">

                    <h:outputText value="#{column.Item3}" />

            </rich:column>

    </rich:dataTable>

    ...

## Note:

The <rich:columns> tag is initialized during components tree building process. This process precedes page rendering at "Render Response" JSF phase. To be rendered properly the component needs all it variables to be initialized while the components tree is being building. A javax.servlet.jsp.JspTagException occurs if <rich:columns> uses variables passed from other components, if these variables are initialized during rendering. Thus, when <rich:columns> is asking for such variables they do not already exist. Use <c:forEach> JSP standard tag as workaround. Compare two examples below.

This code calls the exception:

    ...

    <rich:dataTable value="#{bean.data}" var="var">

              <rich:columns value="#{var.columns}">

                 ...

              </rich:columns>

    </rich:dataTable>

    ...

This code works properly:

    ...

    <c:forEach items="#{bean.data}" var="var">

              <rich:columns value="#{var.columns}">

                 ...

              </rich:columns>

    </c:forEach>

    ...

Information about sorting and filtering you can find here .

### 6.33.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:columns> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:columns> component

### 6.33.7. Skin Parameters Redefinition

Skin parameters redefinition for <rich:columns> are the same as for the <rich:dataTable> component .

### 6.33.8. Definition of Custom Style Classes

Custom style classes for <rich:columns> are the same as for the <rich:dataTable> component .

In order to redefine styles for all <rich:columns> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above ) and define necessary properties in them.

Example:

    ...

    .rich-table-subheadercell{

            color: #a0a0a0;

    }

    ...

This is a result:

Figure 6.40. Redefinition styles with predefined classes

In the example column header cells color was changed.

Also it's possible to change styles of particular <rich:columns> component. In this case you should create own style classes and use them in corresponding <rich:columns> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass {

            font-style: oblique;

    }

    ...

The "styleClass" attribute for <rich:columns> is defined as it's shown in the example below:

Example:

    <rich:columns  styleClass="myClass">

This is a result:

Figure 6.41. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for columns was changed.

## 6.34. < rich:columnGroup >

### 6.34.1. Description

The component combines columns in one row to organize complex subparts of a table.

Figure 6.42. <rich:columnGroup> component

### 6.34.2. Key Features

- Completely skinned table columns and child elements

- Possibility to combine columns and rows inside

- Possibility to update a limited set of strings with Ajax

Table 6.125. rich : columnGroup attributes

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
columnClasses | Comma-delimited list of CSS style classes that are be applied to the columns of this table. A space separated list of classes may also be specified for any individual column. If the number of elements in this list is less than the number of columns specified in the "columns" attribute, no "class" attribute is output for each column greater than the number of elements in the list. If the number of elements in the list is greater than the number of columns specified in the "columns" attribute, the elements at the position in the list after the value of the "columns" attribute are ignored
dir | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left)
filterMethod | This attribute is defined with method binding. This method accepts on Object parameter and return boolean value
filterValue | Defines current filtering value
id | Every component may have a unique id that is automatically created if omitted
lang | Code describing the language used in the generated markup for this component
rendered | If "false", this component is not rendered
rowClasses | A comma-delimited list of CSS style classes that is applied to popup table rows. A space separated list of classes may also be specified for any individual row. The styles are applied, in turn, to each row in the table. For example, if the list has two elements, the first style class in the list is applied to the first row, the second to the second row, the first to the third row, the second to the fourth row, etc. In other words, we keep iterating through the list until we reach the end, and then we start at the beginning again
selfSorted | Manages if the header of the column is clickable, icons rendered and sorting is fired after click on the header. You need to define this attribute inside <rich:dataTable> component
sortOrder | SortOrder is an enumeration of the possible sort orderings.
style | CSS style(s) is/are to be applied when this component is rendered
styleClass | Corresponds to the HTML class attribute
title | Advisory title information about markup elements generated for this component

### 6.34.3. Creating the Component with a Page Tag

To create the simplest variant of columnGroup on a page, use the following syntax:

Example:

    ...

            <rich:columnGroup>

                    <rich:column>

                            <h:outputText value="Column1"/>

                    </rich:column>

                    <rich:column>

                            <h:outputText value="Column2"/>

                    </rich:column>

            </rich:columnGroup>

    ...

### 6.34.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlColumnGroup;

    ...

    HtmlColumnGroup myRow = new HtmlColumnGroup();

    ...

### 6.34.5. Details of Usage

The <rich:columnGroup> component combines columns set wrapping them into the <tr> element and outputting them into one row. Columns are combined in a group the same way as when the "breakBefore" attribute is used for columns to add a moving to the next rows, but the first variant is clearer from a source code. Hence, the following simple examples are very same.

Example:

    ...

        <rich:dataTable value="#{capitalsBean.capitals}" var="cap" rows="5" id="sublist">

            <rich:column colspan="3">

                <f:facet name="header">State Flag</f:facet>

                <h:graphicImage value="#{cap.stateFlag}"/>

            </rich:column>

            <rich:columnGroup>

                <rich:column>

                    <h:outputText value="#{cap.state}"/>

                </rich:column>

                <rich:column >

                    <h:outputText value="#{cap.name}"/>

                </rich:column>

                <rich:column >

                    <h:outputText value="#{cap.timeZone}"/>

                </rich:column>

            </rich:columnGroup>

        </rich:dataTable>

    ...

And representation without a grouping:

Example:

    ...

        <rich:dataTable value="#{capitalsBean.capitals}" var="cap" rows="5" id="sublist">

            <rich:column colspan="3">

                <f:facet name="header">State Flag</f:facet>

                <h:graphicImage value="#{cap.stateFlag}"/>

            </rich:column>

            <rich:column breakBefore="true">

                    <h:outputText value="#{cap.state}"/>

            </rich:column>

            <rich:column breakBefore="true">

                    <h:outputText value="#{cap.name}"/>

            </rich:column>

            <rich:column >

                    <h:outputText value="#{cap.timeZone}"/>

            </rich:column>

        </rich:dataTable>

    ....

The result is:

Figure 6.43. Generated <rich:columnGroup> component with "breakBefore" attribute

It's also possible to use the component for output of complex headers in a table. For example adding of a complex header to a facet for the whole table looks the following way:

Example:

    ...

        <f:facet name="header">

            <rich:columnGroup>

                <rich:column rowspan="2">

                    <h:outputText value="State Flag"/>

                </rich:column>

                <rich:column colspan="3">

                    <h:outputText value="State Info"/>

                </rich:column>

                <rich:column breakBefore="true">

                    <h:outputText value="State Name"/>

                </rich:column>

                <rich:column>

                    <h:outputText value="State Capital"/>

                </rich:column>

                <rich:column>

                    <h:outputText value="Time Zone"/>

                </rich:column>

            </rich:columnGroup>

        </f:facet>

    ...

Generated on a page as:

Figure 6.44. <rich:columnGroup> with complex headers

### 6.34.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:columnGroup> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:columnGroup> component

### 6.34.7. Skin Parameters Redefinition

Skin parameters redefinition for <rich:columnGroup> are the same as for the <rich:dataTable> component.

### 6.34.8. Definition of Custom Style Classes

Custom style classes for <rich:columnGroup> are the same as for the <rich:dataTable> component.

In order to redefine styles for all <rich:columnGroup> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-table-cell{

            color:  #316ac5;

    }

    ...

This is a result:

Figure 6.45. Redefinition styles with predefined classes

In the example cells color was changed.

Also it's possible to change styles of particular <rich:columnGroup> component. In this case you should create own style classes and use them in corresponding <rich:columnGroup> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            background-color: #c0c0c0;

    }

    ...

The "columnClasses" attribute for <rich:columnGroup> is defined as it's shown in the example below:

Example:

    <rich:columnGroup  columnClasses="myClass">

This is a result:

                <h:outputText value="#{cap.timeZone}"/>

            </rich:column>

        </rich:dataTable>

    ...

The result is:

Figure 6.48. Generated <rich:column> component

Now, in order to group columns with text information into one row in one column with a flag, use the "colspan" attribute, which is similar to an HTML one, specifying that the first column contains 3 columns. In addition, it's necessary to specify that the next column begins from the first row with the help of the `breakBefore="true"`.

Example:

    ...

         <rich:dataTable value="#{capitalsBean.capitals}" var="cap" rows="5">

            <rich:column colspan="3">

                <h:graphicImage value="#{cap.stateFlag}"/>

            </rich:column>

            <rich:column breakBefore="true">

                <h:outputText value="#{cap.state}"/>

            </rich:column>

            <rich:column >

                <h:outputText value="#{cap.name}"/>

            </rich:column>

            <rich:column>

                <h:outputText value="#{cap.timeZone}"/>

            </rich:column>

        </rich:dataTable>

    ...

As a result the following structure is rendered:

Figure 6.49. <rich:column> modified with "colspan" and "breakbefore" attributes

The same way is used for columns grouping with the "rowspan" attribute that is similar to an HTML one responsible for rows quantity definition occupied with the current one. The only thing to add in the example is an instruction to move onto the next row for each next after the second column.

Example:

    ...

        <rich:dataTable value="#{capitalsBean.capitals}" var="cap" rows="5">

            <rich:column rowspan="3">

                <f:facet name="header">State Flag</f:facet>

                <h:graphicImage value="#{cap.stateFlag}"/>

            </rich:column>

            <rich:column>

                <f:facet name="header">State Info</f:facet>

                <h:outputText value="#{cap.state}"/>

            </rich:column>

            <rich:column breakBefore="true">

                <h:outputText value="#{cap.name}"/>

            </rich:column>

            <rich:column breakBefore="true">

                <h:outputText value="#{cap.timeZone}"/>

            </rich:column>

        </rich:dataTable>

    ...

As a result:

Figure 6.50. <rich:column> generated with "rowspan" attribute

Hence, additionally to a standard output of a particular row provided with the <h:column> component, it becomes possible to group easily the rows with special HTML attribute.

The columns also could be grouped in a particular way with the help of the <h:columnGroup> component that is described in the following chapter.

Here you can find additional information about dynamic columns.

### 6.35.6. Sorting and Filtering

#### 6.35.6.1. Sorting

In order to sort the columns you should use "sortBy" attribute that indicates what values to be sorted. In order to sort the column you should click on its header. See the following example.

Example:

    ...

    <h:form>

        <rich:dataTable value="#{capitalsBean.capitals}" var="cap" width="300px">

            <f:facet name="header">

                <h:outputText value="Sorting Example"/>

            </f:facet>

            <rich:column sortBy="#{cap.state}">

                <f:facet name="header">

                    <h:outputText value="State Name"/>

                </f:facet>

                <h:outputText value="#{cap.state}"/>

            </rich:column>

            <rich:column sortBy="#{cap.name}">

                <f:facet name="header">

                    <h:outputText value="State Capital"/>

                </f:facet>

                <h:outputText value="#{cap.name}"/>

            </rich:column>

        </rich:dataTable>

    </h:form>

    ...

This is result:

Figure 6.51. <rich:column> with "sortBy" attribute

The "selfSorted" attribute that would add the possibility of automatic sorting by clicking the column header. Default value is "true". In the example below the second column is unavailable for sorting.

Example:

    ...

    <rich:dataTable value="#{capitalsBean.capitals}" var="cap">

            <rich:column>

                    <f:facet name="header">

                            <h:outputText value="State Flag"/>

                    </f:facet>

                    <h:graphicImage value="#{cap.stateFlag}"/>

            </rich:column>

            <rich:column sortBy="#{cap.state}" selfSorted="false">

                    <f:facet name="header">

                            <h:outputText value="State Name"/>

                    </f:facet>

                    <h:outputText value="#{cap.state}"/>

            </rich:column>

    </rich:dataTable>

    ...

"sortOrder" attribute is used for changing the sorting of columns by means of external controls.

Possible values are:

- "ASCENDING" - column is sorted in ascending

- "DESCENDING" - column is sorted in descending

- "UNSORTED" - column isn't sorted

Example:

    ...

    <h:form>

        <rich:dataTable value="#{capitalsBean.capitals}" var="cap" width="300px">

            <f:facet name="header">

                <h:outputText value="Sorting Example"/>

            </f:facet>

            <rich:column sortBy="#{cap.state}" sortOrder="ASCENDING">

                <f:facet name="header">

                    <h:outputText value="State Name"/>

                </f:facet>

                <h:outputText value="#{cap.state}"/>

            </rich:column>

            <rich:column sortBy="#{cap.name}" sortOrder="DESCENDING">

                <f:facet name="header">

                    <h:outputText value="State Capital"/>

                </f:facet>

                <h:outputText value="#{cap.name}"/>

            </rich:column>

        </rich:dataTable>

    </h:form>

    ...

Below you can see the result:

Figure 6.52. <rich:column> with "sortOrder" attribute

In the example above the first column is sorted in descending order. But if recurring rows appear in the table the relative second column are sorted in ascending order.

You can customize the sorting's icon element using "rich-sort-icon" class.

The "sortPriority" attribute defines a set of column ids in the order the columns could be set.

If the columns sort order changed externally sort priorities could be used to define which columns will be sorted first.

The "sortable" attribute which is used with <rich:scrollableDataTable> component. In the following example only the first column could be sorted.

Example:

    ...

    <rich:scrollableDataTable rowKeyVar="rkv" frozenColCount="1"

            id="carList" columnClasses="col" value="#{dataTableScrollerBean.allCars}" var="category"

            sortMode="single" binding="#{dataTableScrollerBean.table}"

            selection="#{dataTableScrollerBean.selection}">

            <rich:column id="make" sortable="true">

                    <f:facet name="header">

                            <h:outputText styleClass="headerText" value="Make"/>

                    </f:facet>

                    <h:outputText value="#{category.make}"/>

            </rich:column>

            <rich:column id="model">

                    <f:facet name="header">

                            <h:outputText styleClass="headerText" value="Model"/>

                    </f:facet>

                    <h:outputText value="#{category.model}"/>

            </rich:column>

            <rich:column id="price">

                    <f:facet name="header">

                            <h:outputText styleClass="headerText" value="Price"/>

                    </f:facet>

                    <h:outputText value="#{category.price}"/>

            </rich:column>

    </rich:scrollableDataTable>

    ...

Figure 6.53. The "sortable" attribute usage

"sortExpression" attribute defines a bean property which is used for sorting of a column.

#### 6.35.6.2. Filtering

There are two ways to filter the column value:

- Using built-in filtering. It uses `startsWith()` function to make filtering. In this case you need to define "filterBy" attribute at column you want to be filterable. This attribute defines iterable object property which is used when filtering performed.

  The "filterValue" attribute is used to get or change current filtering value. It could be defined with initial filtering value on the page or as value binding to get/change it on server. If the "filterValue" attribute isn't empty from the beginning table is filtered on the first rendering.

  You can customize the input form using "rich-filter-input" CSS class.

  In order to change filter event you could use "filterEvent" attribute on column, e.g. "onblur"(default value).

  Below you can see the example:

  Example:

      ...

      <rich:dataTable value="#{capitalsBean.capitals}" var="cap" width="500px">

              <rich:column filterBy="#{cap.state}" filterValue="#{filterName.filterBean}" filterEvent="onkeyup">

                      <h:outputText value="#{cap.state}"/>

              </rich:column>

              <rich:column filterBy="#{cap.name}" filterEvent="onkeyup">

                      <h:outputText value="#{cap.name}"/>

              </rich:column>

      </rich:dataTable>

      ...

  This is the result:

  Figure 6.54. Built-in filtering feature usage

- Using external filtering. In this case you need to write your custom filtering function or expression and define controls.

  The "filterExpression" attribute is used to define expression evaluated to boolean value. This expression checks if the object satisfies filtering condition.

  The "filterMethod" attribute is defined with method binding. This method accepts on Object parameter and return boolean value. So, this method also could be used to check if the object satisfies filtering condition. The usage of this attribute is the best way for implementing your own complex business logic.

  See the following example:

  Example:

      ...

      <rich:dataTable value="#{capitalsBean.capitals}" var="cap" id="table">

              <rich:column filterMethod="#{filteringBean.filterStates}">

                      <f:facet name="header">

                              <h:inputText value="#{filteringBean.filterValue}" id="input">

                                      <a4j:support event="onkeyup" reRender="table"

                                                           ignoreDupResponses="true" requestDelay="700" focus="input" />

                              </h:inputText>

                      </f:facet>

                      <h:outputText value="#{cap.state}" />

              </rich:column>

              <rich:column filterExpression="#{fn:containsIgnoreCase(cap.timeZone, filteringBean.filterZone)}">

                      <f:facet name="header">

                              <h:selectOneMenu value="#{filteringBean.filterZone}">

                                      <f:selectItems value="#{filteringBean.filterZones}" />

                                      <a4j:support event="onchange" reRender="table" />

                              </h:selectOneMenu>

                      </f:facet>

                      <h:outputText value="#{cap.timeZone}" />

              </rich:column>

      </rich:dataTable>

      ...

### 6.35.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:column> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:column> component

### 6.35.8. Skin Parameters Redefinition

Skin parameters redefinition for <rich:column> are the same as for the <rich:dataTable> component.

### 6.35.9. Definition of Custom Style Classes

Custom style classes for <rich:column> are the same as for the <rich:dataTable> component.

In order to redefine styles for all <rich:column> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-table-cell{

            font-style: italic;

    }

    ...

This is a result:

Figure 6.55. Redefinition styles with predefined classes

In the example cells font style was changed.

Also it's possible to change styles of particular <rich:column> component. In this case you should create own style classes and use them in corresponding <rich:column> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            font-weight: bolder;

    }

    ...

The "styleClass" attribute for <rich:column> is defined as it's shown in the example below:

Example:

    <rich:column styleClass="myClass">

This is a result:

Figure 6.56. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font weight for second column was changed.

### 6.36.2. Key Features

- A completely skinned table and child elements

- Possibility to update a limited set of rows with AJAX

- Possibility to receive values dynamically from a model

Table 6.129. rich : dataGrid attributes

Attribute Name | Description

ajaxKeys | This attribute defines row keys that are updated after an AJAX request
align | Deprecated. This attribute specifies the position of the table with respect to the document. The possible values are "left", "center" and "right". The default value is "left".
bgcolor | Deprecated. This attribute sets the background color for the document body or table cells. This attribute sets the background color of the canvas for the document body (the BODY element) or for tables (the TABLE, TR, TH, and TD elements). Additional attributes for specifying text color can be used with the BODY element. This attribute has been deprecated in favor of style sheets for specifying background color information
binding | The attribute takes a value-binding expression for a component property of a backing bean
border | This attributes specifies the width of the frame around a component. Default value is "0".
captionClass | Space-separated list of CSS style class(es) that are be applied to caption for this component
captionStyle | CSS style(s) is/are to be applied to caption when this component is rendered
cellpadding | This attribute specifies the amount of space between the border of the cell and its contents. Default value is "0".
cellspacing | This attribute specifies the amount of space between the border of the cell and its contents. The attribute also specifies the amount of space to leave between cells. Default value is "0".
columnClasses | Comma-delimited list of CSS style classes that are be applied to the columns of this table. A space separated list of classes may also be specified for any individual column. If the number of elements in this list is less than the number of columns specified in the "columns" attribute, no "class" attribute is output for each column greater than the number of elements in the list. If the number of elements in the list is greater than the number of columns specified in the "columns" attribute, the elements at the position in the list after the value of the "columns" attribute are ignored
columns | Number of columns

### 6.36.3. Creating the Component with a Page Tag

To create the simplest variant of dataGrid on a page, use the following syntax:

Example:

    ...

        <rich:dataGrid value="#{dataTableScrollerBean.allCars}" var="car">

            <h:outputText value="#{car.model}"/>

        </rich:dataGrid>

    ...

### 6.36.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDataGrid;

    ...

    HtmlDataGrid myList = new HtmlDataGrid();

    ...

### 6.36.5. Details of Usage

The component takes a list from a model and outputs it the same way as with <h:panelGrid> for inline data. To define grid properties and styles, use the same definitions as for <h:panelGrid>.

The component allows to:

- Use "header" and "footer" facets for output

- Limit number of output elements ( "elements" attribute) and define first element for output ( "first" attribute)

- Bind pages with <rich:datascroller> component

Here is an example:

Example:

    ...

        <rich:panel style="width:150px;height:200px;">

            <h:form>

                  <rich:dataGrid value="#{dataTableScrollerBean.allCars}" var="car" columns="2" elements="4" first="1">

                      <f:facet name="header">

                          <h:outputText value="Car Store"></h:outputText>

                      </f:facet>

                      <rich:panel>

                          <f:facet name="header">

                              <h:outputText value="#{car.make} #{car.model}"></h:outputText>

                          </f:facet>

                          <h:panelGrid columns="2">

                               <h:outputText value="Price:" styleClass="label"></h:outputText>

                               <h:outputText value="#{car.price}"/>

                               <h:outputText value="Mileage:" styleClass="label"></h:outputText>

                               <h:outputText value="#{car.mileage}"/>

                          </h:panelGrid>

                      </rich:panel>

                      <f:facet name="footer">

                          <rich:datascroller></rich:datascroller>

                      </f:facet>

                  </rich:dataGrid>

            </h:form>

        </rich:panel>

    ...

This is a result:

Figure 6.58. Component usage

The component was created basing on the <a4j:repeat> component and as a result it could be partially updated with Ajax. "ajaxKeys" attribute allows to define row keys that are updated after an Ajax request.

Here is an example:

Example:

    ...

        <rich:dataGrid value="#{dataTableScrollerBean.allCars}" var="car" ajaxKeys="#{listBean.list}"

                            binding="#{listBean.dataGrid}" id="grid" elements="4" columns="2">

            ...

        </rich:dataGrid>

    ...

        <a4j:commandButton action="#{listBean.action}" reRender="grid" value="Submit"/>

    ...

In the example "reRender" attribute contains value of "id" attribute for <rich:dataGrid> component. As a result the component is updated after an Ajax request.

### 6.36.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:dataGrid> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:dataGrid> component

### 6.36.7. Skin Parameters Redefinition

Skin parameters redefinition for <rich:dataGrid> are the same as for the <rich:dataTable> component.

### 6.36.8. Definition of Custom Style Classes

Custom style classes for <rich:dataGrid> are the same as for the <rich:dataTable> component.

In order to redefine styles for all <rich:dataGrid> components on a page using CSS, it's enough to create classes with the same names (possible classes are the same as for the <rich:dataTable> ) and define necessary properties in them.

Example:

    ...

    .rich-table-footercell{

        color:#ff7800;

    }

    ...

This is a result:

Figure 6.59. Redefinition styles with predefined classes

In the example color of footercell was changed.

Also it's possible to change styles of particular <rich:dataGrid> component. In this case you should create own style classes and use them in corresponding <rich:dataGrid> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-style:italic;

    }

    ...

The "columnClasses" attribute for <rich:dataGrid> is defined as it's shown in the example below:

Example:

    <rich:dataGrid ... columnClasses="myClass"/>

This is a result:

Figure 6.60. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for columns was changed.

### 6.37.3. Creating the Component with a Page Tag

To create the simplest variant of dataList on a page, use the following syntax:

Example:

    ...

        <rich:dataList var="car" value="#{dataTableScrollerBean.allCars}" >

            <h:outputText value="#{car.model}"/>

        </rich:dataList>

    ...

### 6.37.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDataList;

    ...

    HtmlDataList myList = new HtmlDataList();

    ...

### 6.37.5. Details of Usage

The <rich:dataList> component allows to generate a list from a model.

The component has the "type" attribute, which corresponds to the "type" parameter for the <UL> HTML element and defines a marker type. Possible values for "type" attribute are: "disc", "circle", "square".

Here is an example:

    ...

        <h:form>

            <rich:dataList var="car" value="#{dataTableScrollerBean.allCars}" rows="5" type="disc" title="Car Store">

                <h:outputText value="#{car.make} #{car.model}"/><br/>

                <h:outputText value="Price:" styleClass="label"></h:outputText>

                <h:outputText value="#{car.price} "/><br/>

                <h:outputText value="Mileage:" styleClass="label"></h:outputText>

                <h:outputText value="#{car.mileage} "/><br/>

            </rich:dataList>

    </h:form>

    ...

This is a result:

Figure 6.62. <rich:dataList> component with "type" attribute

In the example the "rows" attribute limits number of output elements of the list.

"first" attribute defines first element for output. "title" are used for popup title. See picture below:

Figure 6.63. <rich:dataList> component with "title" attribute

The component was created basing on the <a4j:repeat> component and as a result it could be partially updated with Ajax. "ajaxKeys" attribute allows to define row keys that are updated after an Ajax request.

Here is an example:

Example:

    ...

        <rich:dataList value="#{dataTableScrollerBean.allCars}" var="car" ajaxKeys="#{listBean.list}"

                            binding="#{listBean.dataList}" id="list" rows="5" type="disc">

            ...

        </rich:dataList>

    ...

        <a4j:commandButton action="#{listBean.action}" reRender="list" value="Submit"/>

    ...

In the example "reRender" attribute contains value of "id" attribute for <rich:dataList> component. As a result the component is updated after an Ajax request.

### 6.37.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:dataList> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:dataList> component

### 6.37.7. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.64. Style classes

Table 6.133. Classes names that define a list appearance

Class name | Description
--- | ---
rich-datalist | Defines styles for a html <ul> element
rich-list-item | Defines styles for a html <li> element

In order to redefine styles for all <rich:dataList> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-list-item{

        font-style:italic;

    }

    ...

This is a result:

Figure 6.65. Redefinition styles with predefined classes

In the example the font style for list item text was changed.

Also it's possible to change styles of particular <rich:dataLIst> component. In this case you should create own style classes and use them in corresponding <rich:dataList> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        background-color:#ffead9;

    }

    ...

The "styleClass" attribute for <rich:dataList> is defined as it's shown in the example below:

Example:

    <rich:dataList ... styleClass="myClass"/>

This is a result:

Figure 6.66. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, background color for <rich:dataList> was changed.

    ...

    HtmlDataOrderedList myList = new HtmlDataOrderedList();

    ...

### 6.38.5. Details of Usage

The <rich:dataOrderedList> component allows to generate an ordered list from a model.

The component has the "type" attribute, which corresponds to the "type" parameter for the <OL> HTML element and defines a marker type. Possible values for "type" attribute are: "A", "a", "I", "i", "1".

                <h:outputText value="#{car.mileage}" /><br/>

            </rich:dataOrderedList>

        </h:form>

    ...

This is a result:

Figure 6.68. <rich:dataOrderedList> component with "type" attribute

In the example the "rows" attribute limits number of output elements of the list.

"first" attribute defines first element for output. "title" are used for popup title.

The component was created basing on the <a4j:repeat> component and as a result it could be partially updated with Ajax. "ajaxKeys" attribute allows to define row keys that are updated after an Ajax request.

Here is an example:

Example:

    ...

        <rich:dataOrderedList value="#{dataTableScrollerBean.allCars}" var="car" ajaxKeys="#{listBean.list}"

                            binding="#{listBean.dataList}" id="list">

            ...

        </rich:dataOrderedList>

    ...

        <a4j:commandButton action="#{listBean.action}" reRender="list" value="Submit"/>

    ...

In the example "reRender" attribute contains value of "id" attribute for <rich:dataOrderedList> component. As a result the component is updated after an Ajax request.

### 6.38.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:dataOrderedList> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:dataOrderedList> component

### 6.38.7. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

bgcolor | Deprecated. This attribute sets the background color for the document body or table cells. This attribute sets the background color of the canvas for the document body (the BODY element) or for tables (the TABLE, TR, TH, and TD elements). Additional attributes for specifying text color can be used with the BODY element. This attribute has been deprecated in favor of style sheets for specifying background color information
binding | The attribute takes a value-binding expression for a component property of a backing bean
border | This attributes specifies the width of the frame around a component. Default value is "0".
captionClass | Space-separated list of CSS style class(es) that are be applied to caption for this component

    ...

### 6.40.5. Details of Usage

The <rich:dataTable> component is similar to the <h:dataTable> one, except Ajax support and skinnability. Ajax support is possible, because the component was created basing on the <a4j:repeat> component and as a result it could be partially updated with Ajax. "ajaxKeys" attribute allows to define row keys that is updated after an Ajax request.

Here is an example:

Example:

    ...

        <rich:dataTable value="#{capitalsBean.capitals}" var="capitals"

                    ajaxKeys="#{bean.ajaxSet}" binding="#{bean.table}" id="table">

            ...

        </rich:dataTable>

    ...

        <a4j:commandButton action="#{tableBean.action}" reRender="table" value="Submit"/>

    ...

In the example "reRender" attribute contains value of "id" attribute for <rich:dataTable> component. As a result the component is updated after an Ajax request.

The component allows to use "header" , "footer" and "caption" facets for output. See an example below:

Example:

    ...

        <rich:dataTable value="#{capitalsBean.capitals}" var="cap" rows="5">

            <f:facet name="caption"><h:outputText value="United States Capitals" /></f:facet>

            <f:facet name="header"><h:outputText value="Capitals and States Table" /></f:facet>

            <rich:column>

                <f:facet name="header">State Flag</f:facet>

                <h:graphicImage value="#{cap.stateFlag}"/>

                <f:facet name="footer">State Flag</f:facet>

            </rich:column>

            <rich:column>

                <f:facet name="header">State Name</f:facet>

                <h:outputText value="#{cap.state}"/>

                <f:facet name="footer">State Name</f:facet>

            </rich:column>

            <rich:column >

                <f:facet name="header">State Capital</f:facet>

                <h:outputText value="#{cap.name}"/>

                <f:facet name="footer">State Capital</f:facet>

            </rich:column>

            <rich:column>

                <f:facet name="header">Time Zone</f:facet>

                <h:outputText value="#{cap.timeZone}"/>

                <f:facet name="footer">Time Zone</f:facet>

            </rich:column>

            <f:facet name="footer"><h:outputText value="Capitals and States Table" /></f:facet>

        </rich:dataTable>

    ...

This is a result:

Information about sorting and filtering you can find here.

### 6.40.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:dataTable> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:dataTable> component

### 6.40.7. Skin Parameters Redefinition

### 6.40.8. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.79. <rich:dataTable> class names

Table 6.148. Classes names that define a whole component appearance

Class name | Description
--- | ---
rich-table | Defines styles for all table
rich-table-caption | Defines styles for a "caption" facet element

Table 6.149. Classes names that define header and footer elements

Class name | Description
--- | ---
rich-table-header | Defines styles for a table header row
rich-table-header-continue | Defines styles for all header lines after the first
rich-table-subheader | Defines styles for a column header
rich-table-footer | Defines styles for a footer row
rich-table-footer-continue | Defines styles for all footer lines after the first
rich-table-subfooter | Defines styles for a column footer

Table 6.150. Classes names that define rows and cells of a table

Class name | Description
--- | ---
rich-table-headercell | Defines styles for a header cell
rich-table-subheadercell | Defines styles for a column header cell
rich-table-cell | Defines styles for a table cell
rich-table-row | Defines styles for a table row
rich-table-firstrow | Defines styles for a table start row
rich-table-footercell | Defines styles for a footer cell
rich-table-subfootercell | Defines styles for a column footer cell

In order to redefine styles for all <rich:dataTable> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-table-cell{

        font-weight:bold;

    }

    ...

This is a result:

Figure 6.80. Redefinition styles with predefined classes

In the example the font weight for table cell was changed.

Also it's possible to change styles of particular <rich:dataTable> component. In this case you should create own style classes and use them in corresponding <rich:dataTable> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-style:italic;

    }

    ...

The "headerClass" attribute for <rich:dataTable> is defined as it's shown in the example below:

Example:

    <rich:dataTable  ... headerClass="myClass"/>

This is a result:

Figure 6.81. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for header was changed.

## 6.41. < rich:subTable >

### 6.41.1. Description

The component is used for inserting subtables into tables with opportunity to choose data from a model and built-in Ajax updates support.

Figure 6.82. <rich:subTable> element

### 6.41.2. Key Features

- Completely skinned table rows and child elements

- Possibility to insert complex columnGroup subcomponents

### 6.41.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

         <rich:dataTable value="#{capitalsBean.capitals}" var="capitals">

            <rich:column>

                ...

            </rich:column>

            <rich:subTable value=#{capitals.details} var="detail">

                <rich:column>

                    ...

                </rich:column>

            </rich:subTable>

        </rich:dataTable>

    ...

### 6.41.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlSubTable;

    ...

    HtmlSubTable mySubTable = new HtmlSubTable();

    ...

### 6.41.5. Details of Usage

The <rich:subTable> component is similar to the <h:dataTable> one, except Ajax support and skinnability. One more difference is that the component doesn't add the wrapping <table> and <tbody> tags. Ajax support is possible, because the component was created basing on the <a4j:repeat> component and as a result it could be partially updated with Ajax. "ajaxKeys" attribute allows to define row keys that is updated after an Ajax request.

Here is an example:

Example:

    ...

        <rich:dataTable value="#{capitalsBean.capitals}" var="capitals">

            <rich:column>

                ...

            </rich:column>

            <rich:subTable value="#{capitals.details}" var="detail" ajaxKeys="#{bean.ajaxSet}" binding="#{bean.subtable}" id="subtable">

                <rich:column>

                    ...

                </rich:column>

            </rich:subTable>

        </rich:dataTable>

    ...

        <a4j:commandButton action="#{tableBean.action}" reRender="subtable"/>

    ...

In the example "reRender" attribute contains value of "id" attribute for <rich:subTable> component. As a result the component is updated after an Ajax request.

The component allows to use "header" and "footer" facets for output. See an example for <rich:dataTable> component.

### 6.41.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:subTable> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:subTable> component

### 6.41.7. Skin Parameters Redefinition

Skin parameters redefinition for <rich:subTable> are the same as for the <rich:dataTable> component.

### 6.41.8. Definition of Custom Style Classes

Table 6.153. Classes names that define a component appearance

Class name | Description
--- | ---
rich-subtable | Defines styles for all subtable
rich-subtable-caption | Defines styles for a "caption" facet element

Table 6.154. Classes names that define header and footer elements

Class name | Description
--- | ---
rich-subtable-header | Defines styles for a subtable header row
rich-subtable-header-continue | Defines styles for all subtable header lines after the first
rich-subtable-subheader | Defines styles for a column header of subtable
rich-subtable-subfooter | Defines styles for a column footer of subtable
rich-subtable-footer | Defines styles for a subtable footer row
rich-subtable-footer-continue | Defines styles for all subtable footer lines after the first

Table 6.155. Classes names that define rows and cells

rich-subtable-row | Defines styles for a subtable row
rich-subtable-firstrow | Defines styles for a subtable start row
rich-subtable-subfootercell | Defines styles for a column footer cell of subtable
rich-subtable-footercell | Defines styles for a subtable footer cell

Figure 6.83. Style classes

In order to redefine styles for all <rich:subTable> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-subtable-footer{

            font-weight: bold;

    }

    ...

This is a result:

Figure 6.84. Redefinition styles with predefined classes

In the example a footer font weight was changed.

Also it's possible to change styles of particular <rich:subTable> component. In this case you should create own style classes and use them in corresponding <rich:subTable> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

      background-color: #fff5ec;

    }

    ...

The "columnClasses" attribute for <rich:subTable> is defined as it's shown in the example below:

Example:

    <rich:subTable ... columnClasses="myClass"/>

This is a result:

Figure 6.85. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the background color for columns was changed.

## 6.42. < rich:dndParam >

### 6.42.1. Description

This component is used for passing parameters during drag-and-drop operations.

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
id | Every component may have a unique id that is automatically created if omitted
name | A name of this parameter
rendered | If "false", this component is not rendered
type | This attribute defines parameter functionality. Possible values are "drag", "drop" and "default". Default value is "default".
value | The current value for this component

Name | Value
--- | ---
component-type | org.richfaces.DndParam
component-class | org.richfaces.component.html.HtmlDndParam
tag-class | org.richfaces.taglib.DndParamTag

### 6.42.2. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page, nested in one of the drag-and-drop components:

Example:

    ...

        <rich:dragSupport dragType="file">

            <rich:dndParam name="testDrag" value="testDragValue"

                            type="drag"/>

        </rich:dragSupport>

    ...

### 6.42.3. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDndParam;

    ...

    HtmlDndParam myDparam = new HtmlDndParam();

    ...

### 6.42.4. Details of Usage

dndParam is used during drag-and-drop operations to pass parameters to an indicator. At first, a parameter type is defined with the type attribute (to specify parameter functionality), then a parameter name could be defined with the name and value attribute. Although, it's possible to use nested content defined inside dndParam for value definition, instead of the attribute.

Variants of usage:

- Parameters passing for a drag icon when an indicator is in drag.

In this case, dndParam is of a drag type and is defined in the following way:

Example:

    ...

        <rich:dragSupport ...>

            <rich:dndParam type="drag" name="dragging">

                <h:graphicImage value="/img/product1_small.png"/>

            </rich:dndParam>

            <h:graphicImage value="product1.png"/>

        </rich:dragSupport>

    ...

Here dndParam defines an icon that is used by an indicator when a drag is on the place of a default icon (e.g. a minimized image of a draggable element)

- Parameters passing for an indicator informational part during a drag.

In this case dndParam is of a drag type and is defined in the following way:

Example:

    ...

        <rich:dragSupport ...>

            <rich:dndParam type="drag" name="label" value="#{msg.subj}"/>

            ...

        </rich:dragSupport>

    ...

The parameter is transmitted into an indicator for usage in an informational part of the dragIndicator component (inside an indicator a call to {label} happens)

- Parameters passing happens when dragged content is brought onto some zone with dropSupport

In this case dndParam is of a drop type and is defined in the following way:

Example:

    ...

        <rich:dropSupport ...>

            <rich:dndParam type="drop" name="comp" >

                <h:graphicImage height="16" width="16" value="/images/comp.png"/>

            </rich:dndParam>

            ...

        </rich:dropSupport >

    ...

Here, dndParam passes icons into an indicator, if dragged content of a comp type is above the given drop zone that processes it on the next drop event.

### 6.42.5. Look-and-Feel Customization

<rich:dndParam> has no skin parameters and custom style classes, as the component isn't visual.

### 6.42.6. Relevan Resources Links

Here you can see the example of <rich:dndParam> usage and sources for the given example.

## 6.43. < rich:dragIndicator >

### 6.43.1. Description

This is a component for defining what appears under the mouse cursor during drag-and-drop operations. The displayed drag indicator can show information about the dragged elements.

Figure 6.86. <rich:dragIndicator> component

### 6.43.2. Key Features

- Customizable look and feel

- Customizable marker according to the type of dragable elements

Table 6.158. rich : dragIndicator attributes

Attribute Name | Description
--- | ---
acceptClass | Corresponds to the HTML class attribute and added to an indicator when a drop is accepted
binding | The attribute takes a value-binding expression for a component property of a backing bean
id | Every component may have a unique id that is automatically created if omitted
rejectClass | Corresponds to the HTML class attribute and added to an indicator when a drop is rejected
rendered | If "false", this component is not rendered
style | CSS style(s) is/are to be applied when this component is rendered
styleClass | Corresponds to the HTML class attribute

tag-class | org.richfaces.taglib.DragIndicatorTag

### 6.43.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

        <rich:dragIndicator  id="indicator">

            <f:facet name="single">

                <f:verbatim>

                    <b>Single item</b> {DragInfo}

                </f:verbatim>

            </f:facet>

        </rich:dragIndicator>

        ...

        <rich:dragSupport dragType="text" dragIndicator="indicator">

    ...

### 6.43.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDragIndicator;

    ...

    HtmlDragIndicator myDragIndicator = new HtmlDragIndicator();

    ...

### 6.43.5. Details of Usage

In the simplest way the component could be defined empty - in that case a default indicator is shown like this:

Figure 6.87. The simplest <rich:dragIndicator>

For indicator customization you need to define one of the following facets:

- "single"

Indicator shown when dragging a single element.

- "multiple"

Indicator shown when dragging several components (for future components that will support multiple selection).

Thus for specify a look-and-feel you have to define one of these facets and include into it a content that should be shown in indicator.

#### 6.43.5.1. Macro definitions

To place some data from drag or drop zones into component you can use macro definitions. They are being defining in the following way:

- <rich:dndParam> component with a specific name and value is being included into a drag/drop support component (an image can be defined as placed inside <rich:dndParam> without defining a value).

- in needed place a parameter value is included into the marking of indicator using syntax (name of parameter)

For instance, this:

    ...

        <rich:dropSupport...>

            <rich:dndParam name="testDrop">

                <h:graphicImage value="/images/file-manager.png" />

            </rich:dndParam>

        </rich:dropSupport>

    ...

Is placed into indicator as follows:

    ...

        <f:facet name="single">

            {testDrop}

        </f:facet>

    ...

#### 6.43.5.2. Predefined macro definitions

Indicator can accept two default macro definitions:

- marker

- label

Thus including one of these elements in the marking of indicator, in other words after setting up appropriate parameters in DnD components and defining only default indicator - without specifying facets - a developer gets these parameters values displayed in indicator in the order "marker - label".

#### 6.43.5.3. Marker customization

The macro definition "marker" can be customized depending on what a draggable element is located over. For that you should define one of these three parameters (specify a parameter with one of three names):

- `accept`

Parameter will be set instead of {marker} into indicator when a draggable element is positioned over drop zone that accept this type of elements

- `reject`

Parameter is set instead of {marker} into indicator when a draggable element is positioned over drop zone that doesn't accept this type of elements

- `default`

Parameter is set instead of {marker} into indicator when a draggable element is positioned over all the rest of page elements

## Note:

If you use <rich:dragIndicator> inside a form do not forget to use id like `formId:indicatorID` defined in <rich:dragSupport> indicator attribute.

### 6.43.6. Look-and-Feel Customization

The <rich:dragIndicator> component has no skin parameters and special style classes , as it consists of one element generated with a your method on the server. To define some style properties such as an indent or a border, it's possible to use "style" and "styleClass" attributes on the component.

### 6.43.7. Relevant Resources Links

Here you can see the example of <rich:dragIndicator> usage and sources for the given example.

## 6.44. < rich:dragSupport >

### 6.44.1. Description

This component defines a subtree of the component tree as draggable for drag-and-drop operations. Within such a "drag zone," you can click the mouse button on an item and drag it to any component that supports drop operations (a "drop zone"). It encodes all the necessary JavaScript for supporting drag-and-drop operations.

Figure 6.88. <rich:dragSupport> component

### 6.44.2. Key Features

- Encodes all necessary JavaScript to perform drag actions

- Can be used within any component type that provides the required properties for drag operations

- Supports drag-and-drop between different forms

### 6.44.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

        <h:panelGrid id="drag1">

            <rich:dragSupport dragType="item"/>

                <!--Some content to be dragged-->

        </h:panelGrid>

    ...

### 6.44.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDragSupport;

    ...

    HtmlDragSupport myDragZone = new HtmlDragSupport();

    ...

### 6.44.5. Details of Usage

The dragSupport tag inside a component completely specifies the events and JavaScript required to use the component and it's children for dragging as part of a drag-and-drop operation. In order to work, though, dragSupport must be placed inside a wrapper component that outputs child components and that has the right events defined on it. Thus, this example won't work, because the <h:column> tag doesn't provide the necessary properties for redefining events on the client:

Example:

    ...

        <h:column>

            <rich:dragSupport dragIndicator=":form:iii" dragType="text">

                <a4j:actionParam value="#{caps.name}" name="name"/>

            </rich:dragSupport>

            <h:outputText value="#{caps.name}"/>

        </h:column>

    ...

However, using a4j:outputPanel as a wrapper inside <h:column> , the following code could be used successfully:

Example:

    ...

        <h:column>

            <a4j:outputPanel>

                <rich:dragSupport dragIndicator=":form:iii" dragType="text">

                    <a4j:actionParam value="#{caps.name}" name="name"/>

                </rich:dragSupport>

                <h:outputText value="#{caps.name}"/>

            </a4j:outputPanel>

        </h:column>

    ...

This code makes all rows of this column draggable.

One of the main attributes for dragSupport is "dragType" , which associates a name with the drag zone. Only drop zones with this name as an acceptable type can be used in drag-and-drop operations. Here is an example:

Example:

    ...

        <h:panelGrid id="drag1">

            <rich:dragSupport dragType="singleItems" .../>

            <!--Some content to be dragged-->

        </h:panelGrid>

    ...

        <h:panelGrid id="drag2">

            <rich:dragSupport dragType="groups" .../>

            <!--Some content to be dragged-->

        </h:panelGrid>

    ...

        <h:panelGrid id="drop1">

            <rich:dropSupport acceptedTypes="singleItems" .../>

            <!--Drop zone content-->

        </h:panelGrid>

    ...

In this example, the `drop1` panel grid is a drop zone that invokes drag-and-drop for drops of items from the first `drag1` panel grid, but not the second `drag2` panel grid. In the section about dropSupport , you will find an example that shows more detailed information about moving data between tables with drag and drop.

The dragSupport component also has a "value" attribute for passing data into the processing after a drop event.

One more important attribute for <rich:dragSupport> is the "dragIndicator" attribute that point to the component id of the <rich:dragIndicator> component to be used for dragged items from this drag zone. If it isn't defined, a default indicator for drag operations is used.

Finally, the component has the following extra attributes for event processing on the client:

- "ondragstart"

- "ondragend"

You can use your own custom JavaScript functions to handle these events.

## Note:

If you define width for a outputPanel, in Internet Explorer 6 you can perform a drag and drop operation, placing the mouse cursor on the text in the outputPanel only.

Information about the "process" attribute usage you can find here .

### 6.44.6. Look-and-Feel Customization

<rich:dragSupport> has no skin parameters and custom style classes , as the component isn't visual.

### 6.44.7. Relevant Resources Links

Here you can see the example of <rich:dragSupport> usage and sources for the given example.

## 6.45. < rich:dropSupport >

### 6.45.1. Description

This component transforms a parent component into a target zone for drag-and-drop operations. When a draggable element is moved and dropped onto the area of the parent component, Ajax request processing for this event is started.

Figure 6.89. <rich:dropSupport> component

### 6.45.2. Key Features

- Encodes all necessary JavaScript to perform drop actions

- Can be used within any component type that provides the required properties for drop operations

- Built-in Ajax processing

- Supports drag-and-drop between different forms

### 6.45.3. Creating the Component with a Page Tag

This simple example shows how to make a panel component a potential drop target for drag-and-drop operations using "text" elements as the dragged items.

Example:

    ...

        <rich:panel>

            <rich:dropSupport acceptedTypes="text"/>

        </rich:panel>

    ...

### 6.45.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDropSupport;

    ...

    HtmlDropSupport myDragZone = new HtmlDropSupport();

    ...

### 6.45.5. Details of Usage

As shown in the example, the key attribute for <rich:dropSupport> is "acceptedTypes" . This attribute defines the types of draggable items that can be dropped onto the designated drop zone.

The second most important attribute for <rich:dropSupport> is "typeMapping" . This attribute maps a specific type among the acceptable types for draggable items to a specific <rich:dndParam> child element under <rich:dropSupport> .

Example:

    ...

        <rich:dropSupport acceptedTypes="[iconsDragged, textDragged]" typeMapping="{iconsDragged: DropIcon}">

            <rich:dndParam name="DropIcon">

                <h:graphicImage value="/images/drop-icon.png"/>

            </rich:dndParam>

    ...

In this example, dropping a draggable item of an "iconsDragged" type will trigger the use a parameter named `"DropIcon"` in the event processing after a drop event. (Also, an Ajax request is sent, and the action and dropListener defined for the component are called.)

Here is an example of moving records between tables. The example describes all the pieces for drag-and-drop. (To get extra information on these components, read the sections for these components.)

As draggable items, this table contains a list of such items designated as being of type `"text"` :

Example:

    ...

        <rich:dataTable value="#{capitalsBean.capitals}" var="caps">

            <f:facet name="caption">Capitals List</f:facet>

            <h:column>

            <a4j:outputPanel>

                <rich:dragSupport dragIndicator=":form:ind" dragType="text">

                    <a4j:actionParam value="#{caps.name}" name="name"/>

                </rich:dragSupport>

                <h:outputText value="#{caps.name}"/>

            </a4j:outputPanel>

            </h:column>

        </rich:dataTable>

    ...

As a drop zone, this panel will accept draggable items of type `text` and then rerender an element with the ID of `box` :

Example:

    ...

        <rich:panel style="width:100px;height:100px;">

            <f:facet name="header">Drop Zone</f:facet>

            <rich:dropSupport acceptedTypes="text" reRender="box"

                            dropListener="#{capitalsBean.addCapital2}"/>

        </rich:panel>

    ...

As a part of the page that can be updated in a partial page update, this table has an ID of `box` :

Example:

    ...

        <rich:dataTable value="#{capitalsBean.capitals2}" var="cap2" id="box">

            <f:facet name="caption">Capitals chosen</f:facet>

            <h:column>

                <h:outputText value="#{cap2.name}"/>

            </h:column>

        </rich:dataTable>

    ...

And finally, as a listener, this listener will implement the dropped element:

Example:

    ...

        public void addCapital2(DropEvent event) {

            FacesContext context = FacesContext.getCurrentInstance();

            Capital cap = new Capital();

            cap.setName(context.getExternalContext().getRequestParameterMap().get("name").toString());

            capitals2.add(cap);

        }

    ...

Here is the result after a few drops of items from the first table:

Figure 6.90. Results of drop actions

In this example, items are dragged element-by-element from the rendered list in the first table and dropped on a panel in the middle. After each drop, a drop event is generated and a common Ajax request is performed that renders results in the third table.

As with every Ajax action component, <rich:dropSupport> has all the common attributes ( "timeout" , "limitToList" , "reRender" , etc.) for Ajax request customization.

Finally, the component has the following extra attributes for event processing on the client:

- "ondragenter"

- "ondragexit"

- "ondrop"

- "ondropend"

Developers can use their own custom JavaScript functions to handle these events.

Information about the "process" attribute usage you can find here .

### 6.45.6. Look-and-Feel Customization

### 6.48.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

    <rich:dropDownMenu value="Item1">

        <!--Nested menu components-->

    </rich:dropDownMenu>

    ...

### 6.48.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDropDownMenu;

    ...

    HtmlDropDownMenu myDropDownMenu = new HtmlDropDownMenu();

    ...

### 6.48.5. Details of Usage

All attributes except "value" are optional. The "value" attribute defines text to be represented. If you can use the "label" facet, you can even not use the "value" attribute.

Here is an example:

Example:

    ...

    <f:facet name="label">

        <h:graphicImage value="/images/img1.png"/>

    </f:facet>

    ...

Use the "event" attribute to define an event for the represented element that triggers a menu appearance. An example of a menu appearance on a click can be seen below.

Example:

    ...

    <rich:dropDownMenu event="onclick" value="Item1">

        <!--Nested menu components-->

    </rich:dropDownMenu>

    ...

The <rich:dropDownMenu> "submitMode" attribute can be set to three possible parameters:

- `Server` (default)

Regular form submission request is used.

- `Ajax`

Ajax submission is used for switching.

- `None`

The "action" and "actionListener" item's attributes are ignored. Menu items don't fire any submits themselves. The behavior is fully defined by the components nested into items.

## Note:

As the <rich:dropDownMenu> component doesn't provide its own form, use it between <h:form> and </h:form> tags.

The "direction" and "jointPoint" attributes are used for defining aspects of menu appearance.

Possible values for the "direction" attribute are:

- "top-left" - a menu drops to the top and left

- "top-right" - a menu drops to the top and right

- "bottom-left" - a menu drops to the bottom and left

- "bottom-right" - a menu drops to the bottom and right

- "auto" - smart positioning activation

Possible values for the "jointPoint" attribute are:

- "tr" - a menu is attached to the top-right point of the button element

- "tl" - a menu is attached to the top-left point of the button element

- "br" - a menu is attached to the bottom-right point of the button element

- "bl" - a menu is attached to the bottom-left point of the button element

- "auto" - smart positioning activation

By default, the "direction" and "jointPoint" attributes are set to "auto".

Here is an example:

Example:

    ...

    <rich:dropDownMenu value="File" direction="bottom-right" jointPoint="tr">

        <rich:menuItem submitMode="ajax" value="New" action="#{ddmenu.doNew}"/>

        <rich:menuItem   submitMode="ajax"  value="Open" action="#{ddmenu.doOpen}"/>

        <rich:menuGroup value="Save As...">

            <rich:menuItem   submitMode="ajax" value="Text File"  action="#{ddmenu.doSaveText}"/>

            <rich:menuItem   submitMode="ajax" value="PDF File"  action="#{ddmenu.doSavePDF}"/>

        </rich:menuGroup>

        <rich:menuItem  submitMode="ajax" value="Close" action="#{ddmenu.doClose}"/>

        <rich:menuSeparator id="menuSeparator11"/>

        <rich:menuItem  submitMode="ajax" value="Exit"  action="#{ddmenu.doExit}"/>

    </rich:dropDownMenu>

You can correct an offset of the pop-up list relative to the label using the following attributes: "horizontalOffset" and "verticalOffset" .

Here is an example:

Example:

    ...

    <rich:dropDownMenu value="File" direction="bottom-right" jointPoint="tr" horizontalOffset="-15" verticalOffset="0">

        <rich:menuItem submitMode="ajax" value="New" action="#{ddmenu.doNew}"/>

        <rich:menuItem   submitMode="ajax"  value="Open" action="#{ddmenu.doOpen}"/>

        <rich:menuGroup value="Save As...">

            <rich:menuItem   submitMode="ajax" value="Text File"  action="#{ddmenu.doSaveText}"/>

            <rich:menuItem   submitMode="ajax" value="PDF File"  action="#{ddmenu.doSavePDF}"/>

        </rich:menuGroup>

        <rich:menuItem  submitMode="ajax" value="Close" action="#{ddmenu.doClose}"/>

        <rich:menuSeparator id="menuSeparator11"/>

        <rich:menuItem  submitMode="ajax" value="Exit"  action="#{ddmenu.doExit}"/>

    </rich:dropDownMenu>

    ...

This is the result:

Figure 6.93. Using the "horizontalOffset" and "verticalOffset" attributes

The "disabled" attribute is used for disabling whole <rich:dropDownMenu> component. In this case it is necessary to define "disabled" attribute as "true". An example is placed below.

Example:

    ...

    <rich:dropDownMenu value="File"  disabled="true">

        ...

    </rich:dropDownMenu>

    ...

### 6.48.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:dropDownMenu> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:dropDownMenu> component

### 6.48.7. Skin Parameters Redefinition

Class name | Description
--- | ---
rich-label-text-decor | Defines text style for a representation element
rich-ddmenu-label | Defines styles for a wrapper <div> element of a representation element
rich-ddmenu-label-select | Defines styles for a wrapper <div> element of a selected representation element
rich-ddmenu-label-unselect | Defines styles for a wrapper <div> element of an unselected representation element
rich-ddmenu-label-disabled | Defines styles for a wrapper <div> element of a disabled representation element

On the screenshot there are classes names that define styles for component elements.

Figure 6.95. Classes names

Table 6.175. Classes names that define a popup element

Class name | Description
--- | ---
rich-menu-list-border | Defines styles for borders
rich-menu-list-bg | Defines styles for a general background list
rich-menu-list-strut | Defines styles for a wrapper <div> element for a strut of a popup list

In order to redefine styles for all <rich:dropDownMenu> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above) and define necessary properties in them. An example is placed below:

Example:

    ...

    .rich-ddmenu-label-select{

        background-color:  #fae6b0;

        border-color: #e5973e;

    }

    ...

This is a result:

Figure 6.96. Redefinition styles with predefined classes

In the example a label select background color and border color were changed.

Also it's possible to change styles of particular <rich:dropDownMenu> component. In this case you should create own style classes and use them in corresponding <rich:dropDownMenu> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-style: italic;

    }

    ...

The "itemClass" attribute for <rich:dropDownMenu> is defined as it's shown in the example below:

Example:

    <rich:dropDownMenu ... itemClass="myClass"/>

This is a result:

Figure 6.97. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for items was changed.

### 6.49.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

    <rich:extendedDataTable value="#{extendedDT.dataModel}" var="edt">

           <rich:column>

             ...

           </rich:column>

Example:

    import org.richfaces.component.html.HtmlExtendedDataTable;

    ...

    HtmlExtendedDataTable myTable = new HtmlExtendedDataTable();

    ...

### 6.49.5. Details of Usage

The <rich:extendedDataTable> component is similar to the <rich:dataTable> . The data in component is scrollable. You can also set the type of selection ( "none", "single" or "multi" lines). Selection of multiple lines is possible using Shift and Ctrl keys.

Here is an example:

Example:

    ...

    <rich:extendedDataTable id="edt" value="#{extendedDT.dataModel}" var="edt" width="500px" height="500px" selectedClass="dataTableSelectedRow" sortMode="single" selectionMode="multi" selection="#{extendedDT.selection}" rowKeyVar="rkvar" tableState="#{extendedDT.tableState}">

           <rich:column id="id" headerClass="dataTableHeader" width="50" label="Id" sortable="true" sortBy="#{edt.id}" sortIconAscending="dataTableAscIcon" sortIconDescending="dataTableDescIcon">

                  <f:facet name="header">

                         <h:outputText value="Id" />

                  </f:facet>

                  <h:outputText value="#{edt.id}" />

           </rich:column>

           <rich:column id="name" width="300" headerClass="dataTableHeader" label="Name" sortable="true" sortBy="#{edt.name}" sortIconAscending="dataTableAscIcon" sortIconDescending="dataTableDescIcon" filterBy="#{edt.name}" filterEvent="onkeyup" visible="false">

                  <f:facet name="header">

                         <h:outputText value="Name" />

                  </f:facet>

                  <h:outputText value="#{edt.name}" />

           </rich:column>

           <rich:column id="date" width="100" headerClass="dataTableHeader" label="Date" sortable="true" comparator="#{extendedDT.dateComparator}" sortIconAscending="dataTableAscIcon" sortIconDescending="dataTableDescIcon">

                  <f:facet name="header">

                         <h:outputText value="Date" />

                  </f:facet>

                  <h:outputText value="#{edt.date}"><f:convertDateTime pattern="yyyy-MM-dd HH:mm:ss" />

                  </h:outputText>

           </rich:column>

           <rich:column id="group" width="50" headerClass="dataTableHeader" label="Group" sortable="true" sortBy="#{edt.group}" sortIconAscending="dataTableAscIcon" sortIconDescending="dataTableDescIcon">

                  <f:facet name="header">

                         <h:outputText value="Group" />

                  </f:facet>

                  <h:outputText value="#{edt.group}" />

           </rich:column>

    </rich:extendedDataTable>

    ...

Figure 6.99. <rich:extendedDataTable> component with selected multiple lines

Information about sorting and filtering can be found here.

In the example "selection" attribute contains object with selected rows.

## Note:

Attribute "height" is mandatory. The default value is "500px" .

Menu on the right side of the column header is used to perform action: sorting, grouping, hiding columns.

This is an example:

Figure 6.100. Column menu

After selecting a "Group by this column" option, you can see the data grouped. You can collapse and expand groups by clicking on a group header.

This is an example:

Figure 6.101. <rich:extendedDataTable> component with grouped data

The "label" attribute in <rich:column> sets the name of the column, which is used when dragging columns (in drag window) and in context menu, in "Columns" submenu.

Example:

    ...

    <rich:column id="name" label="#{msg['name']}"

    ...

Figure 6.102. <rich:extendedDataTable> component with Drag&Drop column 'Name'

In the component <rich:extendedDataTable> columns can hidden:

Figure 6.103. <rich:extendedDataTable> component with hidden column 'Id' and 'Group'

"tableState" attribute can be used to bind state of the table (column width, column position, visible, sequence, grouping...) to a backing-bean string property, for a later used. This state can be for example saved to a database, and it is different form standard JSF state saving mechanisms.

Example:

    ...

    <rich:extendedDataTable tableState="#{extendedDT.tableState}">

    ...

### 6.49.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

### 6.50.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

        <rich:dropDownMenu value="Active">

            ...

            <rich:menuGroup value="Active">

                <!--Nested menu components-->

            </rich:menuGroup>

            ...

        </rich:dropDownMenu >

    ...

### 6.50.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlMenuGroup;

    ...

    HtmlMenuGroup myMenuGroup = new HtmlMenuGroup();

    ...

### 6.50.5. Details of Usage

The "value" attribute defines the text representation of a group element in the page.

The "icon" attribute defines an icon for the component. The "iconDisabled" attribute defines an icon for when the group is disabled. Also you can use the "icon" and "iconDisabled" facets. If the facets are defined, the corresponding "icon" and "iconDisabled" attributes are ignored and the facets' contents are used as icons. This could be used for an item check box implementation.

Here is an example:

    ...

        <f:facet name="icon">

            <h:selectBooleanCheckbox value="#{bean.property}"/>

        </f:facet>

    ...

The "iconFolder" and "iconFolderDisabled" attributes are defined for using icons as folder icons. The "iconFolder" and "iconFolderDisabled" facets use their contents as folder icon representations in place of the attribute values.

The "direction" attribute is used to define which way to display the menu as shown in the example below:

Possible values are:

- "left - down" - a submenu is attached to the left side of the menu and is dropping down

- "left - up" - a submenu is attached to the left side of the menu and is dropping up

- "right - down" - a submenu is attached to the right side of the menu and is dropping down

- "right - up" - a submenu is attached to the right side of the menu and is dropping up

- "auto - smart" positioning activation

By default, the "direction" attribute is set to "auto".

Here is an example:

    ...

            <rich:menuGroup value="Save As..." direction="left-down">

                    <rich:menuItem   submitMode="ajax" value="Text File"  action="#{ddmenu.doSaveText}"/>

                    <rich:menuItem   submitMode="ajax" value="PDF File"  action="#{ddmenu.doSavePDF}"/>

            </rich:menuGroup>

    ...

This would be the result:

Figure 6.106. Using the "direction" attribute

## Note:

The <rich:menuGroup> component was designed to be used only for pop-up menu list creation.

### 6.50.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:menuGroup> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:menuGroup> component

### 6.50.7. Skin Parameters Redefinition

On the screenshot there are classes names that define styles for component elements.

Figure 6.107. Classes names

Table 6.192. Classes names that define an appearance of group elements

Class name | Description
--- | ---
rich-menu-group | Defines styles for a wrapper <div> element for a group
rich-menu-item-label | Defines styles for a label of an item
rich-menu-item-icon | Defines styles for the left icon of an item
rich-menu-item-folder | Defines styles for the right icon of an item

Table 6.193. Classes names that define different states

Class name | Description
--- | ---
rich-menu-item-label-disabled | Defines styles for a label of a disabled item
rich-menu-item-icon-disabled | Defines styles for the left icon of a disabled item
rich-menu-item-folder-disabled | Defines styles for the right icon of a disabled item
rich-menu-group-hover | Defines styles for a wrapper <div> element of a hover group
rich-menu-item-icon-enabled | Defines styles for the left icon of an enabled item
rich-menu-item-icon-selected | Defines styles for the left icon of a selected item

In order to redefine styles for all <rich:menuGroup> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-menu-item-label-disabled{

            font-style: italic;

    }

    ...

This is a result:

Figure 6.108. Redefinition styles with predefined classes

In the example a disabled label font style was changed.

Also it's possible to change styles of particular <rich:menuGroup> component. In this case you should create own style classes and use them in corresponding <rich:menuGroup> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        background-color: #acbece;

        border: none;

    }

    ...

The "selectClass" attribute for <rich:menuGroup> is defined as it's shown in the example below:

Example:

    <rich:menuGroup value="Save As..." selectClass="myClass">

This is a result:

Figure 6.109. Redefinition styles with own classes and styleClass attributes

Table 6.194. rich : menuItem attributes

Attribute Name | Description
--- | ---
action | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only
binding | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
data | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
disabled | If "true" sets state of the item to disabled state. Default value is "false".
eventsQueue | Name of requests queue to avoid send next request before complete other from same event. Can be used to reduce number of requests of frequently events (key press, mouse move etc.)
focus | id of element to set focus after request completed on client side
icon | Path to the icon to be displayed for the enabled item state
iconClass | Class to be applied to icon element
iconDisabled | Path to the icon to be displayed for the disabled item state.
iconStyle | CSS style rules to be applied to icon element
id | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
immediate | True means, that the default ActionListener should be executed immediately (i.e. during Apply Request Values phase of the request processing lifecycle), rather than waiting until the Invoke Application phase
labelClass | Class to be applied to label element
limitToList | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
onbeforedomupdate | JavaScript code for call before DOM has been updated on client side

onselect | HTML: script expression; The onselect event occurs when you select some menu item
process | Id['s] (in format of call UIComponent.findComponent()) of components, processed at the phases 2-5 in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
rendered | If "false", this component is not rendered
requestDelay | Attribute defines the time (in ms.) that the request will be wait in the queue before it is ready to send. When the delay time is over, the request will be sent to the server or removed if the newest 'similar' request is in a queue already

component-class | org.richfaces.component.html.HtmlMenuItem
component-family | org.richfaces.DropDownMenu
renderer-type | org.richfaces.MenuItemRenderer
tag-class | org.richfaces.taglib.MenuItemTag

### 6.51.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

        <rich:dropDownMenu>

            ...

            <rich:menuItem value="Active"/>

            ...

        <rich:dropDownMenu>

    ...

### 6.51.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlMenuItem;

    ...

    HtmlMenuItem myMenuItem = new HtmlMenuItem();

    ...

### 6.51.5. Details of Usage

The "value" attribute defines the text representation for an item element.

There are two icon-related attributes. The "icon" attribute defines an icon. The "iconDisabled" attribute defines an icon for a disabled item. Also you can use the "icon" and "iconDisabled" facets. If the facets are defined, the corresponding "icon" and "iconDisabled" attributes are ignored and the facets content is shown as an icon. It could be used for an item check box implementation.

Here is an example:

    ...

        <f:facet name="icon">

            <h:selectBooleanCheckbox value="#{bean.property}"/>

        </f:facet>

    ...

The <rich:menuItem> "submitMode" attribute can be set to three possible parameters:

- `Server` (default)

Regular form submission request is used.

- `Ajax`

Ajax submission is used for switching.

- `None`

The "action" and "actionListener" item's attributes are ignored. Menu items don' fire any submits themselves. The behavior is fully defined by the components nested into items.

For example, you can put any content into an item, but, in this case, you should set the "mode" attribute as "none" .

Here is an example:

    ...

        <rich:dropDownMenu>

            ...

            <rich:menuItem submitMode="none">

                <h:outputLink value="www.jboss.org"/>

            </rich:menuItem>

            ...

        <rich:dropDownMenu>

    ...

You can use the "disabled" attribute to set the item state.

Here is an example:

    ...

        <rich:dropDownMenu>

            <rich:menuItem value="Disable" disabled="true"/>

        <rich:dropDownMenu>

    ...

## Note:

The <rich:menuItem> component was designed to be used only for pop-up menu list creation.

Information about the "process" attribute usage you can find here.

### 6.51.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:menuItem> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:menuItem> component

### 6.51.7. Skin Parameters Redefinition

Table 6.196. Skin parameters redefinition for an item

Skin parameters | CSS properties

### 6.51.8. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.111. Classes names

Table 6.200. Classes names that define an appearance of item elements

Class name | Description
--- | ---
rich-menu-item | Defines styles for a wrapper <div> element for an item
rich-menu-item-label | Defines styles for a label of an item
rich-menu-item-icon | Defines styles for the left icon of an item

Table 6.201. Classes names that define different states

Class name | Description
--- | ---
rich-menu-item-disabled | Defines styles for a wrapper <div> element of an item
rich-menu-item-enabled | Defines styles for a wrapper <div> element of an enabled item
rich-menu-item-hover | Defines styles for a wrapper <div> element of a hover item
rich-menu-item-label-disabled | Defines styles for a label of a disabled item
rich-menu-item-icon-disabled | Defines styles for the left icon of a disabled item
rich-menu-item-label-enabled | Defines styles for a label of an enabled item
rich-menu-item-icon-enabled | Defines styles for the left icon of an enabled item
rich-menu-item-label-selected | Defines styles for a label of a selected item
rich-menu-item-icon-selected | Defines styles for the left icon of a selected item

In order to redefine styles for all <rich:menuItem> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-menu-item-disabled{

            font-style: italic;

    }

    ...

This is a result:

Figure 6.112. Redefinition styles with predefined classes

In the example a disabled item font style was changed.

Also it's possible to change styles of particular <rich:menuItem> component. In this case you should create own style classes and use them in corresponding <rich:menuItem> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            border-color: #bed6f8;

            background-color: #ffffff;

    }

    ...

The "styleClass" attribute for <rich:menuItem> is defined as it's shown in the example below:

Example:

    <rich:menuItem ... selectStyle="myClass">

This is a result:

Figure 6.113. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the background color and border color for selected item were changed.

### 6.53.2. Key Features

- No developers JavaScript writing needed to use it on pages

- Presents scriptaculous JavaScript library functionality

Table 6.206. rich : effect attributes

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
disableDefault | Disable default action for target event ( append "return false;" to JavaScript ). Default value is "false".
event | Event on the component or html tag the effect is attached to
for | Id of the target component.
id | Every component may have a unique id that is automatically created if omitted
name | Generated JavaScript name.
params | Parameters passed to the effect function. Example params="{duration:0.2,from:1.0,to:0.1}"
rendered | If "false", this component is not rendered
targetId | The id of the element the effect apply to. Might be component id or client id of jsf component or html tag. If targetId is not defined the value of the attribute 'for' or the 'targetId' option effect play its role
type | Defines the type of effect. Possible values: "Fade", "Blind", "Opacity".

component-class | org.richfaces.component.html.HtmlEffect
component-family | org.richfaces.Effect
renderer-type | org.richfaces.EffectRenderer
tag-class | org.richfaces.taglib.EffectTag

### 6.53.3. Creating the Component with a Page Tag

To create the simplest variant of <rich:effect> on a page, use the following syntax:

Example:

    ...

    <rich:effect for="componentId" type="Appear"/>

    ...

### 6.53.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlRichEffect;

    ...

    HtmlRichEffect myEffect = new HtmlRichEffect();

    ...

### 6.53.5. Details of Usage

It is possible to use <rich:effect> in two modes:

- attached to the JSF components or html tags and triggered by a particular event. Wiring effect with JSF components might occur on the server or client. Wiring with html tag is possible only on the client side

- invoking from the JavaScript code by an effect name. During the rendering, <rich:effect> generates the JavaScript function with defined name. When the function is called, the effect is applied

Those a the typical variants of using:

    ...

    <!-- attaching by event  -->

    <rich:panel>

        <rich:effect event="onmouseout" type="Opacity" params="duration:0.8,from:1.0,to:0.3" />

        .... panel content ....

    </rich:panel>

    ...

    <!--  invoking from JavaScript -->

    <div id="contentDiv">

      ..... div content ......

    </div>

    <input type="button" onclick="hideDiv({duration:0.7})" value="Hide" />

    <input type="button" onclick="showDiv()" value="Show" />

    <rich:effect  name="hideDiv"  for="contentDiv" type="Fade" />

    <rich:effect  name="showDiv"  for="contentDiv" type="Appear" />

    <!-- attaching to window on load and applying on particular page element -->

    <rich:effect for="window" event="onload" type="Appear" params="targetId:'contentDiv',duration:0.8,from:0.3,to:1.0" />

    ...

Figure 6.117. Initial

Figure 6.118. When the mouse cursor is over

"name" attribute defines a name of the JavaScript function that is be generated on a page when the component is rendered. You can invoke this function to activate the effect. The function accesses one parameter. It is a set of effect options in JSON format.

"type" attribute defines the type of an effect. For example, "Fade", "Blind", "Opacity". Have a look at scriptaculous documentation for set of available effect.

"for" attribute defines the id of the component or html tag, the effect is attached to. RichFaces converts the "for" attribute value to the client id of the component if such component is found. If not, the value is left as is for possible wiring with on the DOM element's id on the client side. By default, the target of the effect is the same element that effect pointed to. However, the target element is might be overridden with "targetId" option passed with "params" attribute of with function paramenter.

"params" attribute allows to define the set of options possible for particurar effect. For example, 'duration', 'delay', 'from', 'to'. Additionally to the options used by the effect itself, there are two option that might override the <rich:effect> attribute. Those are:

- "targetId" allows to re-define the target of effect. The option is override the value of "for" attribute.

- "type" defines the effect type. The option is override the value of "type" attribute.

You can use a set of effects directly without defining the <rich:effect> component on a page if it's convenient for you. For that, load the scriptaculous library to the page with the following code:

Example:

    ...

    <a4j:loadScript src="resource://scriptaculous/effect.js" />

    ...

If you do use the <rich:effect> component, there is no need to include this library because it's already here.

For more information look at RichFaces Users Forum.

### 6.53.6. Look-and-Feel Customization

<rich:effect> has no skin parameters and custom style classes, as the component isn't visual.

### 6.54.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:fileUpload />

    ...

### 6.54.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlFileUpload;

    ...

    HtmlFileUpload myFileUpload = new HtmlFileUpload();

    ...

### 6.54.5. Details of Usage

The <rich:fileUpload> component consists of two parts:

- List of files which contains the list of currently chosen files to upload with possibility to manage every file

- Component controls - the bar with controls for managing the whole component

There are two places where uploaded files are stored:

- In the temporary folder (depends on OS) if the value of the `createTempFile` parameter in Ajax4jsf Filter section is "true" (by Default)

      ...

      <init-param>

              <param-name>createTempFiles</param-name>

              <param-value>true</param-value>

      </init-param>

      ...

- In the RAM if the value of the `createTempFile` parameter in Ajax4jsf Filter section is "false". This is a better way for storing small-sized files.

The "uploadData" attribute defines the collection of files uploaded. See the example below.

Example:

    ...

    <rich:fileUpload uploadData="#{bean.data}"/>

    ...

The "fileUploadedListener" is called at server side after every file uploaded and used for the saving files from temporary folder or RAM.

Example:

    ...

    <rich:fileUpload uploadData="#{bean.data}" fileUploadListener="#{bean.listener}"/>

     ...

Automatically files uploading could be performed by means of the "immediateUpload" attribute. If the value of this attribute is "true" files are uploaded automatically once they have been added into the list. All next files in the list are uploaded automatically one by one. If you cancel uploading process next files aren't started to upload till you press the "Upload" button or clear the list.

Example:

    ...

    <rich:fileUpload uploadData="#{bean.data}" fileUploadListener="#{bean.listener}" immediateUpload="true"/>

     ...

The "autoclear" attribute is used to remove automatically files from the list after upload completed. See the simple example below.

Example:

    ...

    <rich:fileUpload uploadData="#{bean.data}" autoclear="true"/>

    ...

The <rich:fileUpload> component provides following restrictions:

- On file types, use "acceptedTypes" attribute to define file types accepted by component. In the example below only files with "html" and "jpg" extensions are accepted to upload.

  Example:

      ...

      <rich:fileUpload acceptedTypes="html, jpg"/>

      ...

- On file size, use the `maxRequestSize` parameter(value in bytes) inside Ajax4jsf Filter section in web.xml:

      ...

      <init-param>

              <param-name>maxRequestSize</param-name>

              <param-value>1000000</param-value>

      </init-param>

      ...

- On max files quantity, use the "maxFilesQuantity" attribute to define max number of files allowed to be uploaded. After a number of files in the list equals to the value of this attribute "Add" button is disabled and nothing could be uploaded even if you clear the whole list. In order to upload files again you should rerender the component. As it could be seen in the example below, only 2 files are accepted for uploading.

  Example:

      ...

      <rich:fileUpload maxFilesQuantity="2"/>

       ...

  This is the result:

  Figure 6.120. <rich:fileUpload> with "maxFilesQuantity" attribute

The <rich:fileUpload> component provides a number of specific event attributes:

- The "onadd" a event handler called on an add file operation

- The "onupload" which gives you a possibility to cancel the upload at client side

- The "onuploadcomplete" which is called after all files from the list are uploaded

- The "onuploadcanceled" which is called after upload has been canceled via cancel control

- The "onerror" which is called if the file upload was interrupted according to any errors

The <rich:fileUpload> component has an embedded Flash module that adds extra functionality to the component. The module is enabled with "allowFlash" attribute set to "true".

These are the additional features that the Flash module provides:

- Multiple files choosing;

- Permitted file types are specified in the "Open File" dialog window;

- A number of additional entry object properties are also available, which can be found here.

Apart from uploading files to the sever without using AJAX, the Flash module provides a number of useful API functions that can be used to obtain information about the uploaded file.

There are 2 ways to obtain the data stored in the FileUploadEntry object.

- By means of JavaScript on the client side. Use the following syntax for that `entries[i].propertyName`. For example `entries[0].state` will return the state of the file the is being processed or has just been processed.

- The properties of `FileUploadEntry` object can be retrieved using the `entry.propertyName` expression in the specific event attributes. For example, `onupload="alert(event.memo.entry.fileName);"` will display a message with the name of the file at the very moment when upload operation starts. A full list of properties can be found here.

The given bellow code sample demonstrates how the properties can be used. Please study it carefully.

    ...

                <head>

                      <script>

                            function _onaddHandler (e) {

                                 var i = 0;

                                 for (; i < e.memo.entries.lenght; i++) {

                                       alert(e.memo.entries[i].creator);  //Shows creators of the added files

                                 }

                            }

                            function _onerrorhandle(e) {

                                 alert(e.memo.entry.fileName + "file was not uploaded due  transfer error");

                            }

                      </script>

                </head>

     ...

Moreover, embedded Flash module provides a smoother representation of progress bar during the uploading process: the polling is performed is not by AJAX, but my means of the flash module.

Figure 6.121. Uploading using Flash module <rich:fileUpload>

However, the Flash module doens't perform any visual representation of the component.

In order to customize the information regarding the ongoing process you could use "label" facet with the following macrosubstitution:

- `{B}`, `{KB}`, `{MB}` contains the size of file uploaded in bytes, kilobytes, megabytes respectively

- `{_B}`, `{_KB}`, `{_MB}` contains the remain file size to upload in bytes, kilobytes, megabytes respectively

- `{ss}`, `{mm}`, `{hh}` contains elapsed time in seconds, minutes and hours respectively

Example:

    ...

    <rich:fileUpload uploadData="#{bean.data}" fileUploadListener="#{bean.listener}">

            <f:facet name="label">

                    <h:outputText value="{_KB}KB from {KB}KB uploaded --- {mm}:{ss}" />

            </f:facet>

    </rich:fileUpload>

    ...

This is the result:

Figure 6.122. <rich:fileUpload> with "label" facet

You could define labels of the component controls with the help of "addControlLabel" , "clearAllControlLabel" , "clearControlLabel" , "stopEntryControlLabel" , "uploadControlLabel" attributes. See the following example.

Example:

    ...

    <rich:fileUpload addControlLabel="Add file..." clearAllControlLabel="Clear all" clearControlLabel="Clear"

                            stopEntryControlLabel="Stop process" uploadControlLabel="Upload file"/>

    ...

This is the result:

Figure 6.123. <rich:fileUpload> with labels

The <rich:fileUpload> component allows to use sizes attributes:

- "listHeight" attribute specify height for list of files in pixels

- "listWidth" attribute specify width for list of files in pixels

In order to disable the whole component you could use the "disabled" attribute. See the following example.

Example:

    ...

    <rich:fileUpload disabled="true"/>

    ...

This is the result:

Figure 6.124. <rich:fileUpload> with "disabled" attribute

It's possible to handle events for fileUpload using JavaScript code. A simplest example of usage JavaScript API is placed below:

Example:

    ...

    <rich:fileUpload  id="upload" disabled="false"/>

    <h:commandButton onclick="${rich:component('upload')}.disable();" value="Disable" />

    ...

<rich:fileUpload> component also provides a number of JavaScript property, that can be used to process uploaded files, file states etc. The given below example illustrates how the `entries[0].state` property can be used to get access to the file state. Full list of JavaScript properties can be found below.

    ...

    <rich:fileUpload fileUploadListener="#{fileUploadBean.listener}"

            maxFilesQuantity="#{fileUploadBean.uploadsAvailable}"

            reRender="table" id="upload"

            immediateUpload="#{fileUploadBean.autoUpload}"

            acceptedTypes="jpg, gif, png, bmp">

                <a4j:support event="onuploadcomplete" reRender="info"  />

    </rich:fileUpload>

    <h:commandButton onclick="if($('j_id232:upload').component.entries[0].state == FileUploadEntry.UPLOAD_SUCCESS) alert ('DONE');" value="Check file state"/>

    ...

The <rich:fileUpload> component allows to use internationalization method to redefine and localize the labels. You could use application resource bundle and define `RICH_FILE_UPLOAD_CANCEL_LABEL`, `RICH_FILE_UPLOAD_STOP_LABEL`, `RICH_FILE_UPLOAD_ADD_LABEL`, `RICH_FILE_UPLOAD_UPLOAD_LABEL`, `RICH_FILE_UPLOAD_CLEAR_LABEL`, `RICH_FILE_UPLOAD_CLEAR_ALL_LABEL`, `RICH_FILE_UPLOAD_PROGRESS_LABEL`, `RICH_FILE_UPLOAD_SIZE_ERROR_LABLE`, `RICH_FILE_UPLOAD_TRANSFER_ERROR_LABLE`, `RICH_FILE_UPLOAD_ENTRY_STOP_LABEL`, `RICH_FILE_UPLOAD_ENTRY_CLEAR_LABEL`, `RICH_FILE_UPLOAD_ENTRY_CANCEL_LABEL` there.

The <rich:fileUpload> component could work together with Seam framework. Here you can see how to configure filters for both of them in web.xml file in order to handle <rich:fileUpload> requests.

### 6.54.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:fileUpload> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:fileUpload> component

Class name | Description
--- | ---
rich-fileupload-table-td | Defines styles for a wrapper <td> element of a list items
rich-fileupload-anc | Defines styles for "Cancel", "Stop", "Clear" links

In order to redefine styles for all <rich:fileUpload> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-fileupload-anc{

        font-weight:bold;

        text-decoration:none;

    }

    ...

This is the result:

Figure 6.127. Redefinition styles with predefined classes

In the example above the font weight and text decoration for "Cancel" and "Clear" links are changed.

Also it's possible to change styles of particular <rich:fileUpload> component. In this case you should create own style classes and use them in the corresponding <rich:fileUpload> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            font-weight:bold;

    }

    ...

The "addButtonClass" attribute for <rich:fileUpload> is defined as it's shown in the example below:

Example:

    <rich:fileUpload ... addButtonClass="myClass"/>

This is the result:

Figure 6.128. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for "Add" button is changed.

    ...

    HtmlGmap myMap = new HtmlGmap();

    ...

### 6.55.5. Details of Usage

To use Google Map in your application, generate a key on Google Map official resource . One key could be used for one directory on the server.

Here are the main settings of initial rendering performed with a component map that are accessible with the following attributes:

- "zoom" defines an approximation size (boundary values 1-18)

- "lat" specifies an initial latitude coordinate in degrees, as a number between -90 and +90

- "lng" specifies an initial longitude coordinate in degrees, as a number between -180 and +180

- "mapType" specifies a type of a rendered map (`G_NORMAL_MAP`, `G_SATELLITE_MAP` (DEFAULT), `G_HYBRID_MAP`)

For example, the city of Paris is shown after rendering with the following initial settings: `lat = "48.44"` , `lng = "2.24"` and `zoom = "5"` .

Figure 6.130. <rich:gmap> initial rendering

It's also possible to set accessible controls on the map with the help of the attributes:

- "showGMapTypeControl" determines whether the controls for a map type definition are switched on

- "showGScaleControl" determines whether the controls for scaling are switched on

- "showGLargeMapControl" determines whether the control for map scale rendering is rendered

Figure 6.131. <rich:gmap> accessible controls

To set all these parameters and perform some activity (Zoom In/Out etc.) is possible with your JavaScript, i.e. declare a name of an object on a map in the "gmapVar" attribute and then call the object directly with API Google Map .

For example, to approximate a map for `gmapVar = "map"` declared inside the component, call `map.zoomIn()` on an event.

Moreover, to add e.g. some JavaScript effects, events defined on it are used.

- "onmouseover"

- "onclick"

- "onmouseout"

- etc.

## Note

Google Map does not support XHTML format of the page. Thus, if you use Facelets and JSF 1.2, do not forget to put the following tags somewhere on the page:

    ...

    <f:view contentType="text/html">...</f:view>

    ...

### 6.55.6. Look-and-Feel Customization

<rich:gmap> component isn't tied to skin parameters, as there is no additional elements on it, except the ones provided with Google Map .

### 6.55.7. Definition of Custom Style Classes

Table 6.231. Classes names that define a component appearance

Class name | Description
--- | ---
rich-gmap | Defines styles for a wrapper <div> element of a component

In order to redefine styles for all <rich:gmap> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above ) and define necessary properties in them.

Example:

    ...

    .rich-gmap{

        font-style:italic;

    }

    ...

This is a result:

Figure 6.132. Redefinition styles with predefined classes

In the example the font style for buttons was changed.

Also it's possible to change styles of particular <rich:gmap> component. In this case you should create own style classes and use them in corresponding <rich:gmap> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-weight:bold;

    }

    ...

The "styleClass" attribute for <rich:gmap> is defined as it's shown in the example below:

Example:

    <rich:gmap ... styleClass="myClass"/>

This is a result:

Figure 6.133. Redefinition styles with own classes and "styleClass" attributes

As it could be seen on the picture above, the font weight for buttons was changed.

### 6.56.5. Details of Usage

Here are the main settings of initial rendering performed with a component map that are accessible with the following attributes:

- "zoom" defines an approximation size (boundary values 1-18)

- "lat" specifies an initial latitude coordinate in degrees, as a number between -90 and +90

        <rich:virtualEarth  style="width:800px;" id="vm" lat="48.833" lng="2.40"

                                         dashboardSize="Normal"  zoom="11" mapStyle="Hybrid" var="map" />

    ...

To set all these parameters and perform some activity (Zoom In/Out etc.) is possible with your JavaScript, i.e. declare a name of an object on a map in the "var" attribute and then call the object directly with API Microsoft Virtual Earth map .

For example, to approximate a map for `var = "map"` declared inside the component, call `map.ZoomIn()` on an event.

Moreover, to add e.g. some JavaScript effects, events defined on it are used.

- "onmouseover"

- "onclick"

- "onmouseout"

- etc.

component-class | org.richfaces.component.html.HtmlHotKey
component-family | org.richfaces.HotKey
renderer-type | org.richfaces.HotKeyRenderer

### 6.57.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:hotKey key="alt+a" handler="alert('alt+A is pressed')" />

    ...

### 6.57.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlHotKey;

    ...

    HtmlHotKey myHotKey = new HtmlHotKey();

    ...

### 6.57.5. Details of Usage

There are two ways to register <rich:hotKey> :

- just place it anywhere on the page. In this case the <rich:hotKey> component is attached to the whole page (html[0] element). This is default scenario.

- attach it with "selector" attribute to all the elements defined using this selector. This attribute uses defined by w3c consortium syntax for CSS rule selector with some jQuery extensions.

The "key" attribute defines the hot key itself which is processed by the component.

After the hot key has been registered and defined you could set the "handler" attribute which determines a JavaScript function to be called every time when corresponding keys are pressed.

Example:

    ...

    <rich:listShuttle var="cap" sourceValue="#{capitalsBean.capitals}" id="ls">

        <rich:column>

            <f:facet name="header">

                <h:outputText value="State flag"/>

            </f:facet>

            <h:graphicImage value="#{cap.stateFlag}"/>

        </rich:column>

        <rich:column>

            <f:facet name="header">

                <h:outputText value="State name"/>

            </f:facet>

            <h:outputText value="#{cap.name}"/>

        </rich:column>

    </rich:listShuttle>

    <rich:hotKey selector="#ls" key="right" handler="#{rich:component('ls')}.copy()"/>

    <rich:hotKey selector="#ls" key="left" handler="#{rich:component('ls')}.remove()"/>

    <rich:hotKey selector="#ls" key="end" handler="#{rich:component('ls')}.copyAll()"/>

    <rich:hotKey selector="#ls" key="home" handler="#{rich:component('ls')}.removeAll()"/>

    ...

In the example above the "selector" attribute is used. So the keys work only if <rich:listShuttle> component is focused.

You could press Right or Left keys in order to move some selected items between lists. You could press Home or End buttons in order to move all items between lists.

With the help of the "timing" attribute you could manage <rich:hotKey> registration timing. There are three possible values of this attribute:

- "immediate" - the component is rendered in browser immediately (by default)

- "onload" - the component is rendered after the page is fully loaded

- "onregistercall" - the component is rendered only after JavaScript API for the key registration is used.

The "type" attribute defines the type of keyboard event. Possible values are: "onkeyup", "onkeypress" and "onkeydown".

The "disableInInput" attribute disables the <rich:hotKey> if it is activated on input elements and the value of this attribute is "true".

The "checkParent" attribute defines the hotkey handling of events generated by child components nested into the parent component to which the <rich:hotKey> is attached.

The <rich:hotKey> component also provides a number of JavaScript API functions. There is an example below.

Example:

    ...

    <h:form id="myForm">

        <rich:hotKey id="myKey" key="ctrl+g" handler="alert('Ctrl+G is pressed')" />

        <button onclick="${rich:component('myKey')}.enable(); return false;">Turn Ctrl+G On</button>

        <button onclick="${rich:component('myKey')}.disable(); return false;">Turn Ctrl+G Off</button>

    </h:form>

    ...

In the example above the Ctrl+G is registered as a global hotkey, so if you press this key combination the alert window with the "Ctrl+G is pressed" text appears. With the help of enable(), disable() JavaScript API fucntions you could enable or disable registered hotkey.

### 6.57.6. JavaScript API

Table 6.237. JavaScript API

Function | Description
--- | ---
add(selector, key, handler) | Adds the hotkey(from key param) for elements targeted by selector. it assigns a handler function to the key
remove() | Removes hotkey registration
enable() | Enables registered hotkey
disable() | Disables registered hotkey

### 6.57.7. Look-and-Feel Customization

<rich:hotKey> has no skin parameters and custom style classes, as the component isn't visual.

### 6.58.3. Creating the Component with a Page Tag

Here is a simple example of how the component can be used on a page:

Example:

    ...

    <rich:inplaceInput value="#{bean.value}"/>

    ...

### 6.58.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.inplaceInput;

    ...

    HtmlInpaceInput myInplaceInput = new InplaceInput();

    ...

### 6.58.5. Details of Usage

The <rich:inplaceInput> component was designed to facilitate displaying and inputting(editing) some data.

The "value" attribute is a value-binding expression for the current value of the component.

The component has three functional states:

- View state displays default label with the value taken from "value" or "defaultLabel" attributes.

  If the initial value of the "value" attribute is "null" or empty string the "defaultLabel" attribute is used to define default label.

  Example:

      ...

      <rich:inplaceInput value="#{bean.value}" defaultLabel="click to edit"/>

      ...

  In the example above the "value" attribute is not initialized therefore "`click to edit`" text, that "defaultLabel" , contains is displayed.

  This is the result:

  Figure 6.137. View state

- Edit state - input representation to allow value edit

  Figure 6.138. Edit state

- Changed state - value representation after it was changed

  Figure 6.139. Changed state

The "editEvent" attribute provides an option to assign a JavaScript action to initiate the change of the state from view/changed to edit. The default value is "onclick".

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" editEvent="ondblclick"/>

    ...

The <rich:inplaceInput> component provides specific event attributes:

- "oneditactivation" which is fired on edit state activation

- "oneditactivated" which is fired when edit state is activated

- "onviewactivation" which is fired on view state activation

- "onviewactivated" which is fired after the component is changed to representation state

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" oneditactivation="if (!confirm('Are you sure you want to change the value?')){return false;}" />

    ...

The given code illustrates how "oneditactivation" attribute works, namely when the state is being changed from view to edit, a confirmation window with a message `"Are you sure you want to change value?"` comes up.

Using the boolean "selectOnEdit" attribute set to true, the text in the input field will be selected when the change from view/changed state to edit occurs.

This is the result:

Figure 6.140. Usage of the "selectOnEdit" attribute

If the <rich:inplaceInput> loses focus, input data is saved automatically and the component displays a new value. Additionally, the data is saved when "Enter" is pressed. Nevertheless, you can use the "showControls" attribute, which makes "Save" and "Cancel" buttons appear next to the input field. If the controls are used, data is not saved automatically when the form loses focus: user has to confirm that he/she wants to save/discard the data explicitly. In both cases(with controls or without them) the input data can be discarded by pressing "Esc" key.

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" showControls="true"/>

    ...

Figure 6.141. Usage "showControls" attribute

You can also position the controls relatively to the input field, by means of

- The "controlsHorizontalPosition" attribute with "left", "right" and "center" definitions

- The "controlsVerticalPosition " attribute with "bottom", "center" and "top" definitions

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" showControls="true" controlsVerticalPosition="bottom" controlsHorizontalPosition="left"/>

    ...

This is the result:

Figure 6.142. Positioning of "Save" and "Cancel" buttons

It is also possible to use "controls" facet in order to replace the default controls with facets content. See the example below.

Example:

    ...

    <rich:inplaceInput defaultLabel="Click here to edit" showControls="true" controlsHorizontalPosition="left" controlsVerticalPosition="bottom" id="inplaceInput">

        <f:facet name="controls">

            <button onclick="#{rich:component('inplaceInput')}.save();" type="button">Save</button>

            <button onclick="#{rich:component('inplaceInput')}.cancel();" type="button">Cancel</button>

        </f:facet>

    </rich:inplaceInput>

    ...

This is the result:

Figure 6.143. "controls" facet usage

## Note:

The "controls" facet also implies using "showControls" attribute and it has to be defined as "true".

Redefinition of the "save" and "cancel" icons can be performed using "saveControlIcon" and "cancelControlIcon" attributes. You need to define the path to where your images are located.

Example:

    ...

    <rich:inplaceInput value="#{bean.value}" defaultLabel='click to edit'

        showControls="true"

        controlsHorizontalPosition="left"

        controlsVerticalPosition="top"

        saveControlIcon="/images/cancel.gif"

        cancelControlIcon="/images/save.gif"/>

        ...

Figure 6.144. Redefining of "save" and "cancel" buttons

The <rich:inplaceInput> component could be rendered with <span> or <div> elements to display its value. In order to change default <span> output, use "layout" attribute with "block" value.

The <rich:inplaceInput> component supports standard "tabindex" attribute. When the component gets focus the edit mode is activated.

The "inputWidth" , "minInputWidth" , "maxInputWidth" attributes are provided to specify the width, minimal width and maximal width for the input element respectively.

Table 6.240. Keyboard usage

Keys and combinations | Description
--- | ---
ENTER | Saves the input data, and changes the state from edit to changed
ESC | Changes the state from edit to view or changed, value is not affected
TAB | Switches between the components

### 6.58.6. JavaScript API

Table 6.241. JavaScript API

Function | Description
--- | ---
edit() | Changes the state to edit
cancel() | Changes its state to the previous one before editing (changed or view)
save() | Changes its state to changed with a new value
getValue() | Gets the current value
setValue(newValue) | Sets the current value (to be implemented)

### 6.58.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:inplaceInput> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:inplaceInput> component

rich-inplace-shadow-tr | Defines styles for the shadow in the top right corner
rich-inplace-shadow-bl | Defines styles for the shadow in the bottom left corner
rich-inplace-shadow-br | Defines styles for the shadow in the bottom right corner

In order to redefine styles for all <rich:inplaceInput> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-inplace-field {

        font-style: italic;

    }

    ...

This is the result:

Figure 6.146. Redefinition styles with predefined classes

In the shown example the font in edit state is changed to bold.

It's aslo possible to change styles of a particular <rich:inplaceInput> component. In this case you should create own style classes and use them in corresponding <rich:inplaceInput> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass {

        color:  #008cca;

    }

    ...

The "viewClass" attribute for the <rich:inplaceInput> is defined as it's shown in the example below:

Example:

    ...<rich:inplaceInput value="click to edit" styleClass="myClass"/>

This is a result:

Figure 6.147. Modificaton of a look and feel with own classes and styleClass attributes

As it could be seen on the picture above, the font color of the text on the component was changed.

      </rich:inplaceSelect>

      ...

  In the example above the "value" attribute is not initialized therefore "`click to edit`" text, that "defaultLabel" , contains is displayed.

  This is the result:

  Figure 6.149. View state

- Edit state - select representation to allow value edit

  Figure 6.150. Edit state

- Changed state - value representation after it was changed

  Figure 6.151. Changed state

You can form the list of the options using <f:selectItem/> and <f:selectItems/> facets.

Please, see the example below.

Example:

    ...

    <rich:inplaceSelect value="#{bean.inputValue}" defaultLabel="click to edit">

        <f:selectItems  value="#{bean.selectItems}"/>

        <f:selectItem itemValue="1" itemLabel="factory"/>

        <f:selectItem itemValue="2" itemLabel="newspaper"/>

    </rich:inplaceSelect>

    ...

In the example above the value of the selected item is available via "value" attribute.

The "editEvent" attribute provides an option to assign an JavaScript action that initiates the change of the state from view to edit. The default value is "onclick".

Example:

    ...

    <rich:inplaceSelect value="#{bean.inputValue}" defaultLabel="Double Click to edit" editEvent="ondblclick">

        <f:selectItems value="#{demo.selectItems}" />

    </rich:inplaceSelect>

    ...

The <rich:inplaceSelect> component provides specific event attributes:

- "oneditactivation" fired on edit state activation

- "oneditactivated" fired when edit state is activated

- "onviewactivation" fired on view state activation

- "onviewactivated" fired after the component is changed to representation state

Example:

    ...

    <rich:inplaceSelect value="#{bean.inputValue}" oneditactivation="if (!confirm('Are you sure you want to change the value?')){return false;}">

        <f:selectItems value="#{demo.selectItems}" />

    </rich:inplaceSelect>

    ...

The given code illustrates how "oneditactivation" attribute works, namely when the state is being changed from view to edit, a confirmation window with a message `"Are you sure you want to change value?"` comes up.

To prevent opening the drop-down list by default, once edit state is activated, set the "openOnEdit" attribute to "false". The default value is "true".

Example:

    ...

    <rich:inplaceSelect value="#{bean.inputValue}" showControls="true" openOnEdit="false">

        <f:selectItems  value="#{bean.selectItems}"/>

    </rich:inplaceSelect>

    ...

This is the result:

Figure 6.152. The "openOnEdit" attribute usage

Nowever, if you want to confirm the data saving explicitly you can use the "showControls" attribute, which makes "Save" and "Cancel" buttons (displayed as icons) appear next to the input field. Edit state can be deactivated by pressing "Esc" key. An option in the drop-drown list can be also selected by pressing "Enter".

Example:

    ...

    <rich:inplaceSelect value="#{bean.inputValue}" showControls="true">

        <f:selectItems  value="#{bean.selectItems}"/>

    </rich:inplaceSelect>

    ...

This is the result:

Figure 6.153. The "showControls" attribute usage

You can also position the controls relatively to the input field, by means of

- The "controlsHorizontalPosition" attribute with "left", "right" and "center" definitions

- The "controlsVerticalPosition " attribute with "bottom" and "top" definitions

Example:

    ...

    <rich:inplaceSelect value="#{bean.inputValue}" controlsHorizontalPosition="left" controlsVerticalPosition="center" showControls="true">

        <f:selectItems  value="#{bean.selectItems}"/>

    </rich:inplaceSelect>

    ...

This is the result:

Figure 6.154. Controls positioning

It is also possible to use "controls" facet in order to replace the default controls with facets content. See the example below.

Please, see the example.

Example:

    ...

    <rich:inplaceSelect value="#{bean.inputValue}" showControls="true">

        <f:facet name="controls">

            <button onclick="#{rich:component('inplaceSelect')}.save();" type="button">Save</button>

            <button onclick="#{rich:component('inplaceSelect')}.cancel();" type="button">Cancel</button>

        </f:facet>

        <f:selectItems  value="#{bean.selectItems}"/>

    </rich:inplaceSelect>

    ...

This is the result:

Figure 6.155. "controls" facet usage

## Note:

The "controls" facet also implies using "showControls" attribute and it has to be defined as "true".

The <rich:inplaceSelect> component could be rendered with <span> or <div> elements to display its value. In order to change default <span> output, use the "layout" attribute with "block" value.

The <rich:inplaceSelect> component supports standard "tabindex" attribute. When the component gets focus the edit mode is activated and drop-down list is opened.

The "selectWidth" , "minSelectWidth" and "maxSelectWidth" attributes are provided to specify the width, minimal width and maximal width for the input element respectively.

In order to specify the height and width parameters for the list items of the component, you can use "listHeight" and " listWidth" attributes.

### 6.59.6. JavaScript API

Table 6.252. JavaScript API

Function | Description
--- | ---
edit() | Changes the state to edit
cancel() | Changes its state to the previous one before editing (changed or view)
save() | Changes its state to changed with a new value
getValue() | Gets the current value
setValue(newValue) | Sets the current value (to be implemented)

### 6.59.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:inplaceSelect> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:inplaceSelect> component

rich-inplace-select-shadow-tr | Defines styles for the top-right shadow
rich-inplace-select-shadow-bl | Defines styles for the bottom-left shadow
rich-inplace-select-shadow-br | Defines styles for the bottom-right shadow

In order to redefine styles for all <rich:inplaceSelect> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-inplace-select-list-decoration{

        background-color: #ecf4fe;

    }

    ...

This is the result:

Figure 6.157. Redefinition styles with predefined classes

In the shown example the background color for list is changed.

It's aslo possible to change styles of a particular <rich:inplaceSelect> component. In this case you should create own style classes and use them in corresponding <rich:inplaceSelect> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass {

        background-color:#bed6f8;

        font-style:italic;}

    ...

The "viewClass" attribute for <rich:inplaceSelect> is defined as it's shown in the example below:

Example:

    <rich:inplaceSelect value="click to edit" viewClass="myClass"/>

This is a result:

Figure 6.158. Modificaton of a look and feel with own classes and styleClass attributes

As it could be seen on the picture above, the font style and background color in view state is changed.

### 6.59.10. Relevant Resources Links

### 6.60.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <rich:inputNumberSlider minValue="0" maxValue="100" step="1"/>

    ...

### 6.60.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlInputNumberSlider;

    ...

    HtmlInputNumberSlider mySlider = new HtmlInputNumberSlider();

    ...

### 6.60.5. Details of Usage

<rich:inputNumberSlider> is used to facilitate your data input with rich UI Controls.

Here is the simplest variant of a slider definition with "minValue" , "maxValue" and "step" (on default is "1") attributes, which define the beginning and the end of a numerical area and a slider property step.

Example:

    <rich:inputNumberSlider></rich:inputNumberSlider>

It generates on a page:

Figure 6.160. Generated <rich:inputNumberSlider>

Using "showInput" (default is "true") and "enableManualInput" (default value is "true") attributes, it's possible to output the input area near the slider, and make it read-only or editable.

To remove input area use `showInput = "false"` :

Example:

    <rich:inputNumberSlider minValue="1"  maxValue="100" showInput="false"/>

It looks at page like:

Figure 6.161. <rich:inputNumberSlider> without input field

It's also possible to switch off displaying of "boundary values" and a toolTip showing on a handle drawing. This could be performed with the help of the component defined attributes: "showBoundaryValues" which is responsible for "boundary values" displaying (default is true) and "showToolTip" which is responsible for tooltTip displaying (default is "true").

Moreover, to add e.g. some JavaScript effects, events defined on it are used.

- "onchange"

- "onmouseover"

- "onclick"

- "onfocus"

- "onmouseout"

- etc.

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"` , {2} for `"ShortConverter.SHORT"` .

### 6.60.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:inputNumberSlider> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:imputNumberSlider> component

### 6.60.8. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.162. Style classes

Table 6.271. Classes names that define a component appearance

Class name | Description
--- | ---
rich-slider | Defines styles for a wrapper table element of a component
rich-inslider-track | Defines styles for a bar
rich-inslider-handler | Defines styles for a slider handler
rich-inslider-handler-selected | Defines styles for a selected handler
rich-inslider-field | Defines styles for a text field
rich-inslider-right-num | Defines styles for the right number
rich-inslider-left-num | Defines styles for the left number
rich-inslider-tip | Defines styles for a hint

In order to redefine styles for all <rich:inputNumberSlider> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above ) and define necessary properties in them. An example is placed below:

Example:

    ...

    .rich-inslider-tip{

        background-color: #FFDAB9;

        font-family: Arial Black;

    }

    ...

This is a result:

Figure 6.163. Redefinition styles with predefined classes

In the example a tip background color and font family was changed.

Also it's possible to change styles of particular <rich:inputNumberSlider> component. In this case you should create own style classes and use them in corresponding <rich:inputNumberSlider> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-style: italic;

        font-weight:bold;

        font-size:12px;

    }

    ...

The "inputClass" attribute for <rich:inputNumberSlider> is defined as it's shown in the example below:

Example:

    <rich: inputNumberSlider ... inputClass="myClass"/>

This is a result:

Figure 6.164. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for input text was changed.

There are also several attributes to define functionality peculiarities:

- "cycled" if the attribute is "true" after the current value reaches the border value it's be reversed to another border value after next increasing/decreasing. In other case possibilities of next increasing/decreasing are locked

- "disabled" is an attribute that defines whether a component is active on a page

- "manualInput" is an attribute that defines whether a keyboard input is possible or only UI controls could be used

Moreover, to add e.g. some JavaScript effects, events defined on it are used

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:inputNumberSpinner> component

### 6.61.7. Skin Parameters Redefinition

Table 6.274. Skin parameters redefinition for a container

Skin parameters | CSS properties
--- | ---
controlBackgroundColor | background-color
panelBorderColor | border-color
subBorderColor | border-bottom-color
subBorderColor | border-right-color

Table 6.275. Skin parameters redefinition for an input field

Skin parameters | CSS properties
--- | ---
buttonSizeFont | font-size
buttonFamilyFont | font-family

### 6.61.8. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.167. Style classes

Table 6.276. Classes names that define a component appearance

Class name | Description
--- | ---
rich-spinner-c | Defines styles for a wrapper table element of a component
rich-spinner-input-container | Defines styles for a container
rich-spinner-input | Defines styles for a wrapper <td> element for input fields
rich-spinner-button | Defines styles for a button
rich-spinner-buttons | Defines styles for all buttons

In order to redefine styles for all <rich:inputNumberSpinner> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above ) and define necessary properties in them. An example is placed below:

Example:

    ...

    .rich-spinner-input{

        font-style:italic;

    }

    ...

This is a result:

Figure 6.168. Redefinition styles with predefined classes

In the example an input text font style was changed.

Also it's possible to change styles of particular <rich:inputNumberSpinner> component. In this case you should create own style classes and use them in corresponding <rich:inputNumberSpinner> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-family: Arial Black;

    }

    ...

The "inputClass" attribute for <rich:inputNumberSpinner> is defined as it's shown in the example below:

Example:

    <rich: inputNumberSpinner ... inputClass="myClass"/>

This is a result:

Figure 6.169. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font family for input text was changed.

## 6.62. < rich:insert >

### 6.62.1. Description

The <rich:insert> component is used for highlighting, source code inserting and, optionally, format the file from the application context into the page.

### 6.62.2. Key Features

- Source code highlighting

- Variety of formats for source code highlighting

Table 6.277. rich : insert attributes

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
content | Defines the String, inserted with this component. This attribute is alternative to "src" attribute.
encoding | Attribute defines encoding for inserted content
errorContent | Attribute defines the alternative content that will be shown in case component cannot read the resource defined with 'src' attribute. If "errorContent" attribute is not defined, the component shown the actual error message in the place where the content is expected
highlight | Defines a type of code
id | Every component may have a unique id that is automatically created if omitted
rendered | If "false", this component is not rendered
src | Defines the path to the file with source code

component-class | org.richfaces.ui.component.html.HtmlInsert
component-family | org.richfaces.ui.Insert
renderer-type | org.richfaces.ui.InsertRenderer
tag-class | org.richfaces.ui.taglib.InsertTag

### 6.62.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

          <rich:insert  src="/pages/sourcePage.xhtml" highlight="xhtml"/>

    ...

### 6.62.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.ui.component.html.HtmlInsert;

    ...

    HtmlInsert myInsert = new HtmlInsert();

    ...

### 6.62.5. Details of Usage

The are two basic attributes. The "src" attribute defines the path to the file with source code. The "highlight" attribute defines the type of a syntax highlighting.

If "highlight" attribute is defined and JHighlight open source library is in the classpath, the text from the file is formated and colorized.

An example is placed below.

Example:

    ...

          <rich:insert  src="/pages/sourcePage.xhtml" highlight="xhtml"/>

    ...

The result of using <rich:insert> component is shown on the picture:

Figure 6.170. Source code highlighting

The <rich:insert> component provides the same functionality as JHighlight. Thus, all names of highlight style classes for source code of particular language could be changed to your names, which are used by the JHighlight library.

### 6.62.6. Look-and-Feel Customization

<rich:insert> has no skin parameters and custom style classes, as the component doesn't have own visual representation.

## 6.63. < rich:jQuery >

### 6.63.1. Description

The <rich:jQuery> allows to apply styles and behaviour to DOM objects.

### 6.63.2. Key Features

- Presents jQuery JavaScript framework functionality

- Able to apply onto JSF components and other DOM objects.

- Works without conflicts with prototype.js library

Table 6.279. rich : jQuery attributes

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
id | Every component may have a unique id that is automatically created if omitted
name | The name of a function that will be generated to execute a query. The "name" attribute is required if "timing" attribute equals to "onJScall"
query | The query string that is executed for a given selector.
rendered | If "false", this component is not rendered
selector | Selector for query. The "selector" attribute uses defined by w3c consortium syntax for CSS rule selector with some jQuery extensions.
timing | The attribute that defines when to perform the query. The possible values are "immediate","onload" and "onJScall". "immediate" performs the query right away. "onload" adds the task to the time when a document is loaded (the DOM tree is created). "onJScall" allows to invoke the query by Javascipt function name defined with "name" attribute. The default value is "immediate".

Table 6.280. Component identification parameters

Name | Value
--- | ---
component-type | org.richfaces.JQuery
component-class | org.richfaces.component.html.HtmlJQuery
component-family | org.richfaces.JQuery
renderer-type | org.richfaces.JQueryRenderer
tag-class | org.richfaces.taglib.JQueryTag

### 6.63.3. Creating the Component with a Page Tag

To create the simplest variant on a page, use the following syntax:

Example:

    ...

          <rich:jQuery selector="#customList tr:odd" timing="onload" query="addClass(odd)" />

    ...

### 6.63.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlJQuery;

    ...

    HtmlJQuery myJQuery = new HtmlJQuery();

    ...

### 6.63.5. Details of Usage

<rich:jQuery> can be used in two main modes:

- as a one-time query applied immediately or on a document ready event

- as a JavaScript function that can be invoked from the JavaScript code

The mode is chosen with "timing" attribute that has the following options:

- "immediate" - applying a query immediately

- "onload" - applying a query when a document is loaded

- onJScall - applying a query by invoked JavaScript function defined with the "name" attribute

Definition of the "name" attribute is mandatory when the value of "timing" attribute is "onJScall". If the "name" attribute is defined when "timing" value equals to "immediate" or "onload", the query is applied according to this value, but you still have an opportunity to invoke it by a function name.

The "selector" attribute defines an object or a list of objects. The query is defined with the "query" attribute.

Here is an example of how to highlight odd rows in a table:

Example:

    ...

    <style>

        .odd {

              background-color: #FFC;

        }

    </style>

    ...

    ...

        <rich:table id="customList" ...>

            ...

        </rich:table>

        ...

        <rich:jQuery selector="#customList tr:odd" timing="onload" query="addClass(odd)" />

    ...

The "selector" attribute uses defined by w3c consortium syntax for CSS rule selector with some jQuery extensions

Those are typical examples of using selector in the <rich:jQuery> component.

Table 6.281. Examples of using selector

Selector | Comment
--- | ---
"p[a]" | In a document all "p" tags with "a" tag inside are selected
"ul/li" | All "li" elements of unordered "ul" lists are selected
"p.foo[a]" | All "p" tags with "foo" class and inserted "a" tag are selected
"input[@name=bar]" | All "input" tags with "name" attribute which value is "bar" are selected
"input[@type=radio][@checked]" | All "input" tags with attribute "type"="radio" and attribute value = "chekced" are selected
"p,span,td" | All tag elements "p" or"span" or "td" are selected
"p#secret" | "p" paragraph element with "id" identification = "secret" is selected
"p span" | "span" tag is a (direct or non-direct) child of "p" tag. If it's necessary, use "p > span" or "p/span" is selected
"p[@foo^=bar]" | "p" tag containing "foo" attribute with textual value beginning with "bar" word is selected
"p[@foo$=bar] " | "p" tag containing "foo" attribute with textual value ending with "bar" word is selected
"p[@foo*=bar] " | "p" tag with "foo" attribute containing substring "bar" in any place is selected
"p//span " | "span" tag that is a (direct or non-direct) child of "p" tag is selected
"p/../span " | "span" tag that is a grandchild of "p" tag is selected

In addition, RichFaces allows using either a component id or client id if you apply the query to a JSF component. When you define a selector, RichFaces examines its content and tries to replace the defined in the selector id with a component id if it's found.

For example, you have the following code:

    ...

        <h:form id="form">

            ...

            <h:panelGrid id="menu">

                <h:graphicImage ... />

                <h:graphicImage ... />

                ...

            </h:panelGrid>

        </h:form>

    ...

The actual id of the <h:panelGrid> table in the browser DOM is `"form:menu"`. However, you still can reference to images inside this table using the following selector:

    ...

        <rich:jQuery selector="#menu img" query="..." />

    ...

You can define the exact id in the selector if you want. The following code reference to the same set of a DOM object:

    ...

        <rich:jQuery selector="#form\\:menu img" query="..." />

    ...

Pay attention to double slashes that escape a colon in the id.

In case when the "name" attribute is defined, <rich:jQuery> generates a JavaScript function that might be used from any place of JavaScript code on a page.

There is an example of how to enlarge the picture smoothly on a mouse over event and return back to the normal size on mouse out:

    ...

        <h:graphicImage onmouseover="enlargePic(this)" width="50" value="/images/price.png"

                    onmouseover="enlargePic(this, {pwidth:'60px'})" onmouseover="releasePic(this)"  />

        <h:graphicImage onmouseover="enlargePic(this)" width="50" value="/images/discount.png"

                    onmouseover="enlargePic(this, {pwidth:'100px'})" onmouseover="releasePic(this)"  />

        ...

        <rich:jQuery name="enlargePic" timing="onJScall" query="animate({width:param.pwidth})" />

        <rich:jQuery name="releasePic" timing="onJScall" query="animate({width:'50px'})"/>

    ...

The JavaScript could use two parameters. The first parameter is a replacement for the selector attribute. Thus, you can share the same query, applying it to the different DOM objects. You can use a literal value or a direct reference for an existing DOM object. The second parameter can be used to path the specific value inside the query. The JSON syntax is used for the second parameter. The "param." namespace is used for referencing data inside the parameter value.

<rich:jQuery> adds styles and behavior to the DOM object dynamically. This means if you replace something on a page during an Ajax response, the applied artifacts is overwritten. But you are allowed to apply them again after the Ajax response is complete.

Usually, it could be done with reRendering the <rich:jQuery> components in the same Ajax interaction with the components these queries are applied to. Note, that queries with "timing" attribute set to "onload" are not invoked even if the query is reRendered, because a DOM document is not fully reloaded during the Ajax interaction. If you need to re-applies query with "onload" value of "timing" attribute, define the "name" attribute and invoke the query by name in the "oncomplete" attribute of the Ajax component.

RichFaces includes jQuery JavaScript framework. You can use the futures of jQuery directly without defining the <rich:jQuery> component on a page if it is convenient for you. To start using the jQuery feature on the page, include the library into a page with the following code:

    ...

        <a4j:loadScript src="resource://jquery.js"/>

    ...

Refer to the jQuery documentation for the right syntax. Remember to use `jQuery()` function instead of `$()`, as soon as jQuery works without conflicts with `prototype.js`.

### 6.63.6. Look-and-Feel Customization

<rich:jQuery> has no skin parameters and custom style classes, as the component isn't visual.

### 6.63.7. Relevant Resources Links

### 6.64.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:listShuttle var="item" sourceValue="#{bean.source}" targetValue="#{bean.target}" converter="listShuttleconverter">

            <h:column>

                    <f:facet name="header">

                            <h:outputText value="Cars" />

                    </f:facet>

                    <h:outputText value="#{item.name}" />

            </h:column>

    </rich:listShuttle>

    ...

### 6.64.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlListShuttle;

    ...

    HtmlListShuttle myListShuttle = new HtmlListShuttle();

    ...

### 6.64.5. Details of Usage

The <rich:listShuttle> component consists of the following parts:

- two item lists (source and target). List consists of items. Each item has three different representations: common, selected, active

- optional caption element

- optional ordering controls set is a set of controls that performs reordering

- move controls set is a set of controls, which performs moving items between lists

The "sourceValue" attribute defines a List or Array of items to be shown in the source list.

The "targetValue" attribute defines a List or Array of items to be shown in the target list.

The "var" attribute could be shared between both Lists or Arrays to define lists on the page.

The "sourceRequired" and "targetRequired" attributes define the case when source and target values are being validated. If the value of both attributes is "true" there should be at least one item in source and target lists. Otherwise validation fails.

Example:

    ...

    <h:form id="myForm">

            <rich:messages>

                    <f:facet name="errorMarker">

                            <h:graphicImage value="/images/ajax/error.gif" />

                    </f:facet>

            </rich:messages>

            <rich:listShuttle id="myListShuttle" sourceValue="#{toolBar.freeItems}" targetValue="#{toolBar.items}"

                                    sourceRequired = "true" targetRequired = "true" var="items" converter="listShuttleconverter"

                                    sourceCaptionLabel="Source List" targetCaptionLabel="Target List">

                    <rich:column>

                            <h:graphicImage value="#{items.iconURI}" />

                    </rich:column>

                    <rich:column>

                            <h:outputText value="#{items.label}" />

                    </rich:column>

            </rich:listShuttle>

            <a4j:commandButton value="Submit" />

    </h:form>

    ...

In the example above the source list is empty. If you submit the form validation fails and error message appears on a page.

This is the result:

Figure 6.172. Style classes

The "converter" attribute is used to convert component data to a particular component's value. For example, when you select items in a list, a converter is used to format a set of objects to a strings to be displayed.

## Note

It is necessary to override the "equals" and "hashCode" methods in your own class!

The "sourceSelection" attribute stores the collection of items selected by you in the source list. The "targetSelection" attribute stores the collection of items selected by you in the target list.

Captions could be added to a list only after it was defined as a "sourceCaption" and "targetCaption" named facets inside the component or defined with the "sourceCaptionLabel" and "targetCaptionLabel" attribute.

    ...

    <rich:listShuttle var="item" sourceValue="#{bean.source}" targetValue="#{bean.target}" sourceSelection="#{bean.sourceSelection}"

                            targetSelection="#{bean.targetSelection}" converter="listShuttleconverter">

            <f:facet name="sourceCaption">

                    <h:outputText value="Cars Store #1" />

            </f:facet>

            <f:facet name="targetCaption">

                    <h:outputText value="Cars Store #2" />

            </f:facet>

            <rich:column>

                    <h:outputText value="#{items.name}" />

            </rich:column>

    </rich:listShuttle>

    ...

The <rich:listShuttle> component provides the possibility to use ordering controls set, which performs reordering in the target item list. Every control has possibility to be disabled.

An ordering controls set could be defined with "topControlLabel" , "bottomControlLabel" , "upControlLabel" , "downControlLabel" attributes.

It is also possible to use "topControl" , "topControlDisabled" , "bottomControl" , "bottomControlDisabled" , "upControl" , "upControlDisabled" , "downControl" , "downControlDisabled" facets in order to replace the default controls with facets content.

Example:

    ...

    <rich:listShuttle var="item" sourceValue="#{bean.source}" targetValue="#{bean.target}" converter="listShuttleconverter">

    ...

            <f:facet name="topControl">

                    <h:outputText value="Move to top" />

            </f:facet>

            <f:facet name="upControl">

                    <h:outputText value="Move up" />

            </f:facet>

            <f:facet name="downControl">

                    <h:outputText value="Move down" />

            </f:facet>

            <f:facet name="bottomControl">

                    <h:outputText value="Move to bottom" />

            </f:facet>

    </rich:listShuttle>

    ...

The <rich:listShuttle> component also provides 4 predefined controls in move controls set for moving items between source and target lists. Every control has possibility to be disabled.

A move controls set could be defined with "copyControlLabel" , "removeControlLabel" , "copyAllControlLabel" , "removeAllControlLabel" attributes.

It is also possible to use "copyControl" , "removeControl" , "copyAllControl" , "removeAllControl" facets in order to replace the default controls with facets content.

    ...

    <rich:listShuttle var="item" sourceValue="#{bean.source}" targetValue="#{bean.target}" converter="listShuttleconverter"

                            copyControlLabel="Copy" removeControlLabel="Remove"

                            copyAllControlLabel="Copy all" removeAllControlLabel="Remove all">

            <h:column>

                    <f:facet name="header">

                            <h:outputText value="Cars" />

                    </f:facet>

                    <h:outputText value="#{item.name}" />

            </h:column>

    </rich:listShuttle>

    ...

Controls rendering is based on the "controlsType" attribute. Possible types are button and none.

## Note

Currently the button controls type is based on <div> element.

The <rich:listShuttle> component allows to use internationalization method to redefine and localize the labels. You could use application resource bundle and define `RICH_SHUTTLES_TOP_LABEL`, `RICH_SHUTTLES_BOTTOM_LABEL`, `RICH_SHUTTLES_UP_LABEL`, `RICH_SHUTTLES_DOWN_LABEL` `RICH_LIST_SHUTTLE_COPY_ALL_LABEL`, `RICH_LIST_SHUTTLE_COPY_LABEL`, `RICH_LIST_SHUTTLE_REMOVE_ALL_LABEL`, `RICH_LIST_SHUTTLE_REMOVE_LABEL` there.

You could also pack `org.richfaces.renderkit.listShuttle` resource bundle with your JARs defining the same properties.

### 6.64.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:listShuttle> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:listShuttle> component

In order to redefine styles for all <rich:listShuttle> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-shuttle-source-row-active{

            background-color:#FFE4B5;

    }

    ...

This is a result:

Figure 6.174. Redefinition styles with predefined classes

In the example an active row background color in the source list was changed.

Also it's possible to change styles of particular <rich:listShuttle> component. In this case you should create own style classes and use them in corresponding <rich:listShuttle> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            font-style:italic;

    }

    ...

The "rowClasses" attribute for <rich:listShuttle> is defined as it's shown in the example below:

Example:

    <rich:listShuttle ... rowClasses="myClass"/>

This is a result:

Figure 6.175. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, font style for row items was changed.

tag-class | org.richfaces.taglib.RichMessageTag

### 6.65.3. Creating the Component with a Page Tag

To create the simplest variant of message on a page, use the following syntax:

Example:

    ...

        <rich:message for="id"/>

    ...

### 6.65.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlRichMessage;

    ...

    HtmlRichMessage myMessage = new HtmlRichMessage();

    ...

### 6.65.5. Details of Usage

The component has the same behavior as standard <h:message> component except next two features:

- It's ajaxRendered. It means that the component is reRendered after Ajax request automatically without outputPanel usage

- The component optionally provides "passed" state which will be shown if no message is displayed

- Provides possibility to add some marker to message. By default a marker element isn't shown

A set of facets which can be used for marker defining:

- "passedMarker" . This facet is provided to allow setting a marker to display if there is no message

- "errorMarker" . This facet is provided to allow setting a marker to display if there is a message with a severity class of "ERROR"

- "fatalMarker" . This facet is provided to allow setting a marker to display if there is a message with a severity class of "FATAL"

- "infoMarker" . This facet is provided to allow setting a marker to display if there is a message with a severity class of "INFO"

- "warnMarker" . This facet is provided to allow setting a marker to display if there is a message with a severity class of "WARN"

The following example shows different variants for component customization. The attribute "passedLabel" is used for definition of the label to display when no message appears. But the message component doesn't appear before the form submission even when state is defined as passed (on initial rendering). Boolean attribute "showSummary" defines possibility to display summary portion of displayed messages. The facets "errorMarker" and "passedMarker" set corresponding images for markers.

Example:

    ...

            <rich:message for="id" passedLabel="No errors' showSummary="true">

                <f:facet name="errorMarker">

                    <h:graphicImage url="/image/error.png"/>

                </f:facet>

                <f:facet name="passedMarker">

                    <h:graphicImage url="/image/passed.png"/>

                </f:facet>

            </rich:message>

    ...

### 6.65.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method.

There are no skin parameters and default predefined values. To redefine the appearance of all <rich:message> components at once, you should only add to your style sheets style classes used by a <rich:message> component.

In the example the font style for message was changed.

Also it's possible to change styles of particular <rich:message> component. In this case you should create own style classes and use them in corresponding <rich:message> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-weight:bold;

    }

    ...

The "styleClass" attribute for <rich:message> is defined as it's shown in the example below:

Example:

    <rich:message ... styleClass="myClass"/>

This is a result:

    <rich:modalPanel id="panel">

        <f:facet name="header">

            <h:outputText value="header" />

        </f:facet>

        ...

        <!--Any Content inside-->

        ...

    <a onclick="Richfaces.hideModalPanel('modalPanelID');" href="#">Hide</a>

    </rich:modalPanel>

    <a onclick="Richfaces.showModalPanel('modalPanelID');" href="#">Show</a>

    ...

### 6.67.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlModalPanel;

    ...

    HtmlModalPanel myPanel = new HtmlModalPanel();

    ...

### 6.67.5. Details of Usage

The component is defined as a panel with some content inside that displays its content as a modal dialog. To call it and to close it, the client API for the window is used.

Table 6.315. Functions description

Function | Description
--- | ---
RichFaces.showModalPanel (client Id) | Opens a window with a specified client Id
RichFaces.hideModalPanel (client Id) | Closes a window with a specified client Id

## Important:

In order to avoid a bug in IE, the root node of the dialog is moved on the top of a DOM tree. However, you should have a separate form inside the modal panel if you want to perform submits from this panel (so, no form should be around the modal panel in this case).

It's possible to add a "header" facet to the component to set the content for the header.

Example:

    ...

        <rich:modalPanel id="panel" width="400" height="300">

            <f:facet name="header">

                <h:outputText value="Modal Panel"/>

            </f:facet>

            <h:graphicImage value="/pages/california_large.png"/>

            <a href="javascript:Richfaces.hideModalPanel('form:panel')">Close</a>

        </rich:modalPanel>

        <a href="javascript:Richfaces.showModalPanel('form:panel');">Open</a>

    ...

This defines a window with a particular size and ID. It includes one "Open" link. Clicking on this link makes the modal window content appear.

Figure 6.185. <rich:modalPanel> with links

A facet named "controls" can be added to the component to place control elements on a header.

Example:

    ...

    <rich:modalPanel id="mp">

        <f:facet name="header">

            <h:outputText value="Modal Panel"/>

        </f:facet>

        <f:facet name="controls">

            <h:graphicImage value="/pages/close.png" style="cursor:pointer" onclick="Richfaces.hideModalPanel('mp')" />

        </f:facet>

        <h:graphicImage value="/pages/california_large.png"/>

    </rich:modalPanel>

    ...

The result is displayed here:

Figure 6.186. <rich:modalPanel> with control element

To manage the placement of inserted windows, use the "zindex" attribute that is similar to the standard HTML attribute and can specify window placement relative to the content.

To manage window placement relative to the component, there are "left" and "top" attributes defining a window shifting relative to the top-left corner of the window.

Modal windows can also support resize and move operations on the client side. To allow or disallow these operations, set the "resizeable" and "moveable" attributes to "true" or "false" values. Window resizing is also limited by "minWidth" and "minHeight" attributes specifying the minimal window sizes.

You can pass your parameters during modalPanel opening or closing. This passing could be performed in the following way:

Example:

    Richfaces.showModalPanel('panelId', {left: auto}, {param1: value1});

Thus, except the standard modalPanel parameters you can pass any of your own parameters.

Also modalPanel allows to handle its own opening and closing events on the client side. The "onshow" and "onclose" attributes are used in this case.

The following example shows how on the client side to define opening and closing event handling in such a way that your own parameters could also be obtained:

Example:

    onshow="alert(event.parameters.param1)"

Here, during modalPanel opening the value of a passing parameter is output.

More information about this problem could be found on the RichFaces Development Forum.

There is a possibility to restore of the previous component state on a page (including position on the screen) after submitting and reloading. The modalPanel has some special attributes like "showWhenRendered" and "keepVisualState" .

"showWhenRendered" - This boolean attribute is used if modalPanel should be rendered after first page loading.

"keepVisualState" - Used if modalPanel should save state after submission. If `keepVisualState="true"` then parameters which modalPanel has during opening should be submitted and passed to new page.

Example:

    ...

    <a href="javascript:Richfaces.showModalPanel('_panel', {top:'10px', left:'10px', height:'400'});">Show</a>

    ...

Here, if you open modal dialog window using current link and after submits data then modalPanel destination and height on new loaded page is restored.

if you need the content of the modalPanel to be submitted - you need to remember two important rules:

- modalPanel must have its own form if it has form elements (input or/and command components) inside (as it was shown in the example above)

- modalPanel must not be included into the form (on any level up) if it has the form inside.

Simple example of using commandButton within modalPanel is placed below.

Example:

    ...

    <rich:modalPanel>

        <f:facet name="header">

            <h:outputText value="Test" />

        </f:facet>

        <f:facet name="controls">

            <h:commandLink value="Close" style="cursor:pointer" onclick="Richfaces.hideModalPanel('mp')" />

        </f:facet>

        <h:form>

            <h:commandButton value="Test" action="#{TESTCONTROLLER.test}" />

        </h:form>

    </rich:modalPanel>

    ...

    <h:form>

        <!--Some other Page content-->

    </h:form>

    ...

See also discussion about this problem on the RichFaces Users Forum.

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"`, {2} for `"ShortConverter.SHORT"`.

Here there is information for those of you who would like to click on a details link in table and have it show a modal panel with information loaded from the server.

### 6.67.6. JavaScript API

Table 6.316. JavaScript API

Function | Description
--- | ---
show() | Opens the corresponding modalPanel

### 6.67.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:modalPanel> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:modalPanel> component

### 6.67.8. Skin Parameters Redefinition

### 6.67.9. Definition of Custom Style Classes

Figure 6.187. <rich:modalPanel> class name

The screenshot shows the classes names for defining different elements.

Table 6.321. Classes names that define a component appearance

Class name | Description
--- | ---
rich-modalpanel | Defines styles for a wrapper <div> element of a modalpanel
rich-mpnl_panel | Defines styles for a modalpanel
rich-mpnl-mask-div | Defines styles for a wrapper <div> element of a mask
rich-mpnl-resizer | Defines styles for a wrapper <div> element of a resizing element
rich-mpnl-shadow | Defines styles for a modalpanel shadow
rich-mpnl-header | Defines styles for a modalpanel header
rich-mpnl-header-cell | Defines styles for a header cell
rich-mpnl-text | Defines styles for a wrapper <div> element of a header text
rich-mpnl-body | Defines styles for a content inside a modalpanel
rich-mpnl-controls | Defines styles for a wrapper <div> element of a modalpanel control

In order to redefine styles for all <rich:modalPanel> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-mpnl-mask-div{

        background-color:#fae6b0;

    }

    ...

This is a result:

Figure 6.188. Redefinition styles with predefined classes

In the example the background color for mask was changed.

Also it's possible to change styles of particular <rich:modalPanel> component. In this case you should create own style classes and use them in corresponding <rich:modalPanel> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-style:italic;

    }

    ...

The "headerClass" attribute for <rich:modalPanel> is defined as it's shown in the example below:

Example:

    <rich:modalPanel ... headerClass="myClass"/>

This is a result:

Figure 6.189. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above,the font style for header was changed.

### 6.68.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:orderingList value="#{bean.list}" var="list">

            <rich:column>

                <f:facet name="header">

            <h:outputText value="Name" />

                </f:facet>

                <h:inputText value="#{list.name}" />

            </rich:column>

    <rich:orderingList>

    ...

### 6.68.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlOrderingList;

    ...

    HtmlOrderingList myOrderingList = new HtmlOrderingList();

    ...

### 6.68.5. Details of Usage

The <rich:orderingList> component consists of

- Item list element that displays a list of items. It has three different representations for a single element: common, selected, active. Combination of these states is possible.

- Ordering controls set

The "value" and "var" attributes are used to access the values of a list.

Controls rendering is based on the "controlsType" attribute. Possible types are button or none.

## Note

Currently the button controls type is based on <div> element.

The "selection" attribute stores the collection of items selected by you. In the example below after submitting the form the current collection is placed in the object's property and then <rich:dataTable> with selected items is shown.

Example:

    ...

    <h:form>

            <rich:orderingList value="#{bean.simpleItems}" var="item" selection="#{bean.selection}" controlsType="button">

                    <rich:column>

                        <f:facet name="header">

                                <h:outputText value="Cars" />

                        </f:facet>

                                <h:outputText value="#{item}" />

                    </rich:column>

            </rich:orderingList>

            <rich:dataTable id="infoPanelID" value="#{bean.info}" var="info" rendered="true">

                    <rich:column>

                                <h:outputText value="#{info}" />

                    </rich:column>

            </rich:dataTable>

            <a4j:commandButton value="reRender" reRender="infoPanelID" />

    </h:form>

    ...

The <rich:orderingList> component allows to use "caption" facet. A caption could be also defined with "captionLabel" attribute.

Simple example is placed below.

Example:

    ...

    <rich:orderingList value="#{bean.simpleItems}" var="item" controlsType="button" selection="#{bean.selection}">

            <f:facet name="caption">

                    <h:outputText value="Caption Facet" />

            </f:facet>

            <rich:column>

                    <f:facet name="header">

                    <h:outputText value="Cars" />

                    </f:facet>

                    <h:outputText value="#{item.name}" />

            </rich:column>

            <rich:column>

                    <f:facet name="header">

                    <h:outputText value="Price" />

                    </f:facet>

                    <h:outputText value="#{item.price}" />

            </rich:column>

    </rich:orderingList>

    ...

The <rich:orderingList> component provides the possibility to use ordering controls set, which performs reordering. Every control has possibility to be disabled.

An ordering controls set could be defined with "topControlLabel" , "bottomControlLabel" , "upControlLabel" , "downControlLabel" attributes.

It is also possible to use "topControl" , "topControlDisabled" , "bottomControl" , "bottomControlDisabled" , "upControl" , "upControlDisabled" , "downControl" , "downControlDisabled" facets in order to replace the default controls with facets content.

Example:

    ...

    <rich:orderingList value="#{bean.simpleItems}" var="item" controlsType="button" selection="#{bean.selection}">

            <f:facet name="topControl">

                    <h:outputText value="Move to top" />

            </f:facet>

            <f:facet name="upControl">

                    <h:outputText value="Move up" />

            </f:facet>

            <f:facet name="downControl">

                    <h:outputText value="Move down" />

            </f:facet>

            <f:facet name="bottomControl">

                    <h:outputText value="Move to bottom" />

            </f:facet>

    <rich:orderingList>

    ...

The position of the controls relatively to a list could be customized with:

- "controlsHorizontalAlign" attribute. Possible values:

  - "left" - controls render to the left side of a list

  - "right" (default) - controls render to the right side of a list

  - "center" - controls is centered

- "controlsVerticalAlign" attribute. Possible values:

  - "top" - controls render aligned to the top side of a list

  - "bottom" - controls render aligned to the bottom side of a list

  - "center" (default) - controls is centered relatively to a list

The <rich:orderingList> component has a possibility to hide any of the controls by pairs using following attributes:

- "orderControlsVisible" attribute has two values: "true" or "false". If false Up and Down controls are not displayed.

- "fastOrderControlsVisible" attribute has two values: "true" or "false". If false Top and Bottom controls are not displayed.

The <rich:orderingList> component allows to use internationalization method to redefine and localize the labels. You could use application resource bundle and define `RICH_SHUTTLES_TOP_LABEL`, `RICH_SHUTTLES_BOTTOM_LABEL`, `RICH_SHUTTLES_UP_LABEL`, `RICH_SHUTTLES_DOWN_LABEL` there.

You could also pack `org.richfaces.renderkit.orderingList` resource bundle with your JARs defining the same properties.

rich-ordering-control-bottom | Defines styles for a "bottom" control
rich-ordering-control-up | Defines styles for a "up" control
rich-ordering-control-down | Defines styles for a "down" control
rich-ordering-control-disabled | Defines styles for controls in disabled state

In order to redefine styles for all <rich:orderingList> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-ordering-list-table-header-cell{

            font-weight:bold;

    }

    ...

This is a result:

Figure 6.192. Redefinition styles with predefined classes

In the example the font weight for header text was changed.

Also it's possible to change styles of particular <rich:orderingList> component. In this case you should create own style classes and use them in corresponding <rich:orderingList> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            font-style:italic;

    }

    ...

The "rowClasses" attribute for <rich:orderingList> is defined as it's shown in the example below:

Example:

    <rich:orderingList ... rowClasses="myClass"/>

This is a result:

Figure 6.193. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for rows was changed.

## 6.69. < rich:paint2D >

### 6.69.1. Description

Create image by painting from a managed bean method, same as "paint" (Graphics2D) in "SWING" components.

Figure 6.194. <rich:paint2D> component

### 6.69.2. Key Features

- Simple Graphics2D - painting style directly on the Web page

- Supports client/server caching for generated images

- Fully supports "JPEG" (24-bit, default), "GIF" (8-bit with transparency), and "PNG" (32-bit with transparency) formats for sending generated images

- Easily customizable borders and white space to wrap the image

- Dynamically settable paint parameters using tag attributes

Table 6.348. rich : paint2D attributes

Attribute Name | Description
--- | ---
align | Deprecated. This attribute specifies the position of an IMG, OBJECT, or APPLET with respect to its context. The possible values are "bottom", "middle", "top", "left" and "right". The default value is "middle".
bgcolor | Background color of painted image. Default value is 'transparent' which means no background fill. Hex colors can be used, as well as common color names. Invalid values are treated as transparent. Note, that JPEG format doesn't support transparency, and transparent background is painted black. Also note, that several browsers (e.g. IE6) do not support PNG transparency
binding | The attribute takes a value-binding expression for a component property of a backing bean
border | Deprecated. This attribute specifies the width of an IMG or OBJECT border, in pixels. The default value for this attribute depends on the user agent
cacheable | Supported (or not) client/server caching for generated images. Caching on client supported by properly sending and processing of HTTP headers (Last-Modified, Expires, If-Modified-Since, etc.) Server-side caching is supported by application-scope object cache. For build of cache key use "value" attribute, serialized to URI
data | Value calculated at render time and stored in Image URI (as part of cache Key), at paint time passed to a paint method. It can be used for updating cache at change of image generating conditions, and for creating paint beans as "Lightweight" pattern components (request scope). IMPORTANT: Since serialized data stored in URI, avoid using big objects
format | format Name of format for sending a generated image. It currently supports "jpeg" (24 bit, default), "gif" (8 bit with transparency), "png" (32 bit with transparency)
height | Height in pixels of image (for paint canvas and HTML attribute). Default value is "10".
hspace | Deprecated. This attribute specifies the amount of white space to be inserted to the left and right of an IMG, APPLET, or OBJECT. The default value is not specified, but is generally a small, non-zero length
id | Every component may have a unique id that is automatically created if omitted
lang | Code describing the language used in the generated markup for this component
paint | The method calls expression to paint Image on prepared Buffered image. It must have two parameters with a type of java.awt.Graphics2D (graphics to paint) and Object (restored from URI "data" property). For painting used 32-bit RGBA color model (for 8-bit images used Diffusion filtration before sending)
rendered | If "false", this component is not rendered
style | CSS style(s) is/are to be applied when this component is rendered
styleClass | Corresponds to the HTML class attribute
title | Advisory title information about markup elements generated for this component
value | The current value of this component
vspace | Deprecated. This attribute specifies the amount of white space to be inserted above and below an IMG, APPLET, or OBJECT. The default value is not specified, but is generally a small, non-zero length
width | Width in pixels of image (for paint canvas and HTML attribute). Default value is "10".

Table 6.349. Component identification parameters

Name | Value

component-class | org.richfaces.component.html.HtmlPaint2D
component-family | javax.faces.Output
renderer-type | org.richfaces.Paint2DRenderer
tag-class | org.richfaces.taglib.Paint2DTag

### 6.69.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <rich:paint2D paint="#{paint2D.paint}" data="#{paint2DModel}"/>

    ...

Here "paint" specifies the method performing drawing and "data" specifies Managed Bean property keeping the data used by the method.

### 6.69.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPaint2D;

    ...

    HtmlPaint2D myImage = new HtmlPaint2D();

    ...

### 6.69.5. Details of Usage

The example shows two main attributes of the component:

- "paint"

  Specify a method receiving an object specified in data as a parameter and sending graphical information into the stream

- "data"

  Specifies a bean class keeping your data for rendering

## Note:

Data object should implement serializable interface

The "format" attribute of the component defines a format of visual data passing to the server.

Generated data can be used as a cacheable or non-cacheable resource. It's defined with "cacheable" attribute. If cache support is turned on, a key is created in URI with a mix of size (width/height), `"paint"` method, "format" and "data" attributes.

Example:

    paintBean.java:

          public void paint(Graphics2D g2, Object obj) {

              // code that gets data from the data Bean (PaintData)

              PaintData data = (PaintData) obj;

              ...

              // a code drawing a rectangle

              g2.drawRect(0, 0, data.Width, data.Height);

              ...

              // some more code placing graphical data into g2 stream below

         }

    dataBean.java:

        public class PaintData implements Serializable{

            private static final long serialVersionUID = 1L;

            Integer Width=100;

            Integer Height=50;

            ...

        }

        page.xhtml:

        ...

        <rich:paint2D paint="#{paint2D.paint}" data="#{paint2DModel.data}"/>

        ...

### 6.69.6. Look-and-Feel Customization

Paint2D has no skin parameters and special style classes, as it consists of one element generated with a your method on the server.

To define some style properties such as an indent or a border, it's possible to use "style" and "styleClass" attributes on the component.

### 6.69.7. Relevant Resources Links

Here you can see the example of <rich:paint2D> usage and sources for the given example.

## 6.70. < rich:panel >

### 6.70.1. Description

A skinnable panel that is rendered as a bordered rectangle with or without a header.

Figure 6.195. <rich:panel> component

### 6.70.2. Key Features

- Highly customizable look and feel

- Support for any content inside

- Header adding feature

Table 6.350. rich : panel attributes

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
bodyClass | A class that defines a style for a panel content

component-family | org.richfaces.panel
renderer-type | org.richfaces.PanelRenderer
tag-class | org.richfaces.taglib.PanelTag

### 6.70.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

        <rich:panel header="Panel Header">

            ...

            <!--Any Content inside-->

            ...

        </rich:panel>

    ...

### 6.70.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPanel;

    ...

    HtmlPanel myPanel = new HtmlPanel();

    ...

### 6.70.5. Details of Usage

The "header" attribute defines text to be represented. If you can use the "header" facet, you can even not use the "header" attribute.

Example:

    ...

        <rich:panel>

            <f:facet name="header">

                <h:graphicImage value="/images/img1.png"/>

            </f:facet>

            ...

            <!--Any Content inside-->

            ...

        </rich:panel>

    ...

<rich:panel> components are used to group page content pieces on similarly formatted rectangular panels.

Example:

    ...

        <rich:panel>

            ...

        </rich:panel>

    ...

It's generating on a page in the following way:

Figure 6.196. <rich:panel> without header

The example shows that similar rectangular areas are formed with a particular style.

When creating a panel with a header element, one more <div> element is added with content defined for a header.

Example:

    ...

        <rich:panel>

            <f:facet name="header">

                <h:outputText value="Olympus EVOLT E-500 "/>

            </f:facet>

            ...

        </rich:panel>

    ...

It's displayed on a page in the following way:

Figure 6.197. <rich:panel> with header

As it has been mentioned above, the component is mostly used for a page style definition, hence the main attributes are style ones.

- "styleClass"

- "headerClass"

- "bodyClass"

Moreover, to add e.g. some JavaScript effects, events defined on it are used.

- "onmouseover"

- "onclick"

- "onmouseout"

- etc.

### 6.70.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:panel> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:panel> component

### 6.70.7. Skin Parameters Redefinition

Table 6.352. Skin parameters redefinition for a whole component

Skin parameters | CSS properties
--- | ---
generalBackgroundColor | background-color
panelBorderColor | border-color

### 6.70.8. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.198. Style classes

Table 6.355. Classes names that define a component appearance

Class name | Class description
--- | ---
rich-panel | Defines styles for a wrapper <div> element of a component
rich-panel-header | Defines styles for a header element
rich-panel-body | Defines styles for a body element

In order to redefine styles for all <rich:panel> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above) and define necessary properties in them. An example is placed below:

Example:

    ...

    .rich-panel-body{

        background-color: #ebf3fd;

    }

    ...

This is a result:

Figure 6.199. Redefinition styles with predefined classes

In the example a body background color was changed.

Also it's possible to change styles of particular <rich:panel> component. In this case you should create own style classes and use them in corresponding <rich:panel> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        text-align: justify;

    }

    ...

The "bodyClass" attribute for <rich:panel> is defined as it's shown in the example below:

Example:

    <h:panel... bodyClass="myClass"/>

This is a result:

Figure 6.200. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, text align of body was changed.

## 6.71. < rich:panelBar >

### 6.71.1. Description

panelBar is used for grouping any content which is loaded on the client side and appears as groups divided on child panels after the header is clicked.

Figure 6.201. <rich:panelBar> with content inside

### 6.71.2. Key Features

- Skinnable slide panel and child items

- Groups any content inside each panel

Table 6.356. rich : panelBar attributes

Attribute Name | Description
--- | ---
binding | The attribute takes a value-binding expression for a component property of a backing bean
contentClass | The component content style class

            <!--//... -->

            <rich:panelBarItem label="Canon">

                ...

            </rich:panelBarItem>

            <rich:panelBarItem label="Nikon">

                ...

            </rich:panelBarItem>

        </rich:panelBar>

    ...

### 6.71.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPanelBar;

    ...

    HtmlPanelBar myBar = new HtmlPanelBar();

    ...

### 6.71.5. Details of Usage

As it was mentioned above, panelBar is used for grouping any content on the client, thus its customization deals only with specification of sizes and styles for rendering.

"width" and "height" (both are 100% on default) attributes stand apart.

Style attributes are described further.

panelBar could contain any number of child panelBarItem components inside, which content is uploaded onto the client and headers are controls to open the corresponding child element.

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"`, {2} for `"ShortConverter.SHORT"`.

### 6.71.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:panelBar> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:panelBar> component

### 6.71.7. Skin Parameters Redefinition

Table 6.358. Skin parameter redefinition for a whole component

Skin parameter | CSS properties

headerBackgroundColor | border-color

### 6.71.8. Definition of Custom Style Classes

There is one predefined class for the <rich:panelBar> , which is applicable to a whole component, specifying padding, borders, and etc.

Figure 6.202. Style classes

Table 6.359. Class name that define a component appearance

Class name | Class description
--- | ---
rich-panelbar | Defines styles for a wrapper <div> element of a component

Other classes responsible for elements rendering are described for child <rich:panelBarItem> elements and could be found in the components chapters.

Table 6.360. Style component classes

A class attribute | A component element defined by an attribute
--- | ---
styleClass | Applicable to a whole component (together with headers)
headerClass | Applicable to a header element
contentClass | Applicable to a content

In order to redefine styles for all <rich:panelBar> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-panelbar{

            font-style: italic;

    }

    ...

This is a result:

Figure 6.203. Redefinition styles with predefined classes

In the example header and content font style was changed.

Also it's possible to change styles of particular <rich:panelBar> component. In this case you should create own style classes and use them in corresponding <rich:panelBar> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

           font-family: Tahoma;

    }

    ...

The "contentClass" attribute for <rich:panelBar> is defined as it's shown in the example below:

Example:

    <rich:panelBar ... contentClass="myClass"/>

This is a result:

In order to redefine styles for all <rich:panelBarItem> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-panelbar-content{

In the example a content background color was changed.

Also it's possible to change styles of particular <rich:panelBarItem> component. In this case you should create own style classes and use them in corresponding <rich:panelBarItem> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

      font-family: monospace;

    }

    ...

The "headerClass" attribute for <rich:panelBarItem> is defined as it's shown in the example below:

Example:

    <rich:panelBarItem ... headerClass="myClass"/>

This is a result:

Table 6.368. Component identification parameters

Name | Value
--- | ---
component-type | org.richfaces.PanelMenu
component-class | org.richfaces.component.html.HtmlPanelMenu
component-family | org.richfaces.PanelMenu
renderer-type | org.richfaces.PanelMenuRenderer
tag-class | org.richfaces.taglib.PanelMenuTag

### 6.73.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

          <rich:panelMenu event="onmouseover">

                <!--Nested panelMenu components-->

          </rich:panelMenu>

    ...

### 6.73.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPanelMenu;

    ...

    HtmlPanelMenu myPanelMenu = new HtmlPanelMenu();

    ...

### 6.73.5. Details of Usage

All attributes are not required.

Use "event" attribute to define an event for appearance of collapsing/expanding sublevels. Default value is "onclick". An example could be seen below.

Example:

    ...

          <rich:panelMenu event="onmouseover">

                <!--Nested panelMenu components-->

          </rich:panelMenu>

    ...

Switching mode could be chosen with the "mode" attribute for all panelMenu items except ones where this attribute was redefined. By default all items send traditional request.

The "expandMode" attribute defines the submission modes for all collapsing/expanding panelMenu groups except ones where this attribute was redefined.

The "mode" and "expandMode" attributes could be used with three possible parameters. The "mode" attribute defines parameters for all included <rich:panelMenuItem> elements.

- `Server` (default)

The common submission of the form is performed and a page is completely refreshed.

Example:

    ...

          <rich:panelMenu mode="server">

              <rich:panelMenuGroup label="test Group" action="#{bean.action}">

                  <rich:panelMenuItem label="test" action="#{capitalsBean.action}">

                      <f:param value="test value" name="test"/>

                  </rich:panelMenuItem>

              </rich:panelMenuGroup>

          </rich:panelMenu>

    ...

- `Ajax`

An Ajax form submission is performed, and additionally specified elements in the "reRender" attribute are reRendered.

Example:

    ...

          <rich:panelMenu mode="ajax">

               <rich:panelMenuGroup label="test Group" action="#{bean.action}">

                   <rich:panelMenuItem label="test" reRender="test" action="#{capitalsBean.action}">

                       <f:param value="test value" name="test"/>

                   </rich:panelMenuItem>

              </rich:panelMenuGroup>

          </rich:panelMenu>

    ...

- `None`

"Action" and "ActionListener" item's attributes are ignored. Items don't fire any submits itself. Behavior is fully defined by the components nested into items.

Example:

    ...

          <rich:panelMenu event="onclick" submitMode="none">

                <rich:panelMenuItem label="Link to external page">

                      <h:outputLink ... >

                <rich:panelMenuItem>

          </rich:panelMenu>

    ...

## Note:

As the <rich:panelMenu> component doesn't provide its own form, use it between <h:form> and </h:form> tags.

The "expandSingle" attribute is defined for expanding more than one submenu on the same level. The default value is "false" . If it's true the previously opened group on the top level closes before opening another one. See the picture below.

Figure 6.210. Using the "expandSingle" attribute

The "selectedChild" attribute is used for defining the name of the selected group or item. An example for group is placed below:

Here is an example:

Example:

    ...

          <rich:panelMenu selectedChild="thisChild">

            <rich:panelMenuGroup label="Group1" name="thisChild">

              <!--Nested panelMenu components-->

            </rich:panelMenuGroup>

          </rich:panelMenu>

          ...

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"`, {2} for `"ShortConverter.SHORT"`.

### 6.73.6. JavaScript API

In Java Script code for expanding/collapsing group element creation it's necessary to use `expand()`/`collapse()` function.

Table 6.369. JavaScript API

Function | Description
--- | ---
expand() | Expands group element
collapse() | Collapses group element

### 6.73.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method.

There are no skin parameters. To redefine the appearance of all <rich:panelMenu> components at once, you should add to your style sheets the style class used by a <rich:panelMenu> component.

### 6.73.8. Definition of Custom Style Classes

Table 6.370. Classes names that define a component appearance

Class name | Class description
--- | ---
rich-pmenu | Defines styles for a wrapper <div> element of a component
rich-pmenu-top-group | Defines styles for a top group element of a component

In order to redefine styles for all <rich:panelMenu> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-pmenu{

        font-style:italic;

    }

    ...

This is a result:

Figure 6.211. Redefinition styles with predefined classes

In the example the font style was changed.

Also it's possible to change styles of particular <rich:panelMenu> component. In this case you should create own style classes and use them in corresponding <rich:panelMenu> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        background-color: #ecf4fe;

    }

    ...

The "hoveredItemClass" attribute for <rich:panelMenu> is defined as it's shown in the example below:

Example:

    <rich:panelMenu ... hoveredItemClass="myClass"/>

This is a result:

Figure 6.212. Redefinition styles with own classes and "styleClass" attributes

As it could be seen on the picture above,background color for hovered item was changed.

### 6.73.9. Relevant Resources Links

Here you can see the example of <rich:panelMenu> usage and sources for the given example.

## 6.74. < rich:panelMenuGroup >

### 6.74.1. Description

The <rich:panelMenuGroup> component is used to define an expandable group of items inside the panel menu or other group.

Figure 6.213. <rich:panelMenuGroup> component

### 6.74.2. Key Features

- Highly customizable look-and-feel

- Different submission modes inside every group

- Optional submissions on expand collapse groups

- Custom and predefined icons supported

- Support for disabling

### 6.74.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

          <rich:panelMenu>

                <rich:panelMenuGroup label="Group1">

                      <!--Nested panelMenu components-->

                </rich:panelMenuGroup>

          </rich:panelMenu>

    ...

### 6.74.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPanelMenuGroup;

    ...

    HtmlPanelMenuGroup myPanelMenuGroup = new HtmlPanelMenuGroup();

    ...

### 6.74.5. Details of Usage

All attributes except "label" are optional. The "label" attribute defines text to be represented.

Switching mode could be chosen with the "expandMode" attribute for the concrete panelMenu group.

The "expandMode" attribute could be used with three possible parameters:

- `ServerM` (default)

Regular form submission request is used.

- `Ajax`

Ajax submission is used for switching.

- `None`

"Action" and "actionListener" attributes are ignored. Items don't fire any submits itself. Behavior is fully defined by the components nested into items.

There are three icon-related attributes. The "iconExpanded" attribute defines an icon for an expanded state. The "iconCollapsed" attribute defines an icon for a collapsed state. The "iconDisabled" attribute defines an icon for a disabled state.

Default icons are shown on the picture below:

Figure 6.214. Default icons

Here is an example:

Example:

    ...

          <rich:panelMenu>

                <rich:panelMenuGroup label="Group1" iconExpanded="disc" iconCollapsed="chevron">

                      <!--Nested panelMenu components-->

                </rich:panelMenuGroup>

          </rich:panelMenu>

    ...

As the result the pictures are shown below. The first one represents the collapsed state, the second one - expanded state:

Figure 6.215. Collapsed state

Figure 6.216. Expanded state

It's also possible to define a path to the icon. Simple code is placed below.

    ...

          <rich:panelMenu>

                <rich:panelMenuGroup label="Group1" iconExpanded="\images\img1.png" iconCollapsed="\images\img2.png">

                      <!--Nested menu components-->

                </rich:panelMenuGroup>

          </rich:panelMenu>

    ...

Information about the "process" attribute usage you can find here.

### 6.74.6. JavaScript API

In Java Script code for expanding/collapsing group element creation it's necessary to use `expand()`/`collapse()` function.

Table 6.373. JavaScript API

Function | Description

### 6.74.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:panelMenuGroup> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:panelMenuGroup> component

### 6.74.8. Skin Parameters Redefinition

Table 6.381. Classes names that define a group state

Class name | Description
--- | ---
rich-pmenu-hovered-element | Defines styles for a hovered group element
rich-pmenu-disabled-element | Defines styles for a disabled group element

In order to redefine styles for all <rich:panelMenuGroup> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-pmenu-disabled-element{

            color: #87b9ff;

    }

    ...

This is a result:

Figure 6.219. Redefinition styles with predefined classes

In the example a disabled element font style and color were changed.

Also it's possible to change styles of particular <rich:panelMenuGroup> component. In this case you should create own style classes and use them in corresponding <rich:panelMenuGroup> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

           background-color: #ecf4fe;

    }

    ...

The "hoverClass" attribute for <rich:panelMenuGroup> is defined as it's shown in the example below:

Example:

    <rich:panelMenuGroup ... hoverClass="myClass"/>

This is a result:

Figure 6.220. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the background color for hovered item was changed.

Table 6.383. Component identification parameters

Name | Value
--- | ---
component-type | org.richfaces.PanelMenuItem
component-class | org.richfaces.component.html.HtmlPanelMenuItem
component-family | org.richfaces.PanelMenuItem
renderer-type | org.richfaces.PanelMenuItemRenderer
tag-class | org.richfaces.taglib.PanelMenuItemTag

### 6.75.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

          <rich:panelMenu>

                 ...

                <rich:panelMenuItem value="Item1"/>

                ...

          </rich:panelMenu>

    ...

### 6.75.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPanelMenuItem;

    ...

    HtmlPanelMenuItem myPanelMenuItem = new HtmlPanelMenuItem();

    ...

### 6.75.5. Details of Usage

All attributes except "label" are optional. The "label" attribute defines text to be represented.

The "mode" attribute could be used with three possible parameters:

- `Server` (default)

Regular form submission request is used.

- `Ajax`

Ajax submission is used for switching.

- `None`

"Action" and "actionListener" attributes are ignored. Items don't fire any submits itself. Behavior is fully defined by the components nested into items.

Here is an example for value "none":

Example:

    ...

          <rich:panelMenu>

                ...

                <rich:panelMenuItem submitMode="none" onclick="document.location.href='http://labs.jboss.com/jbossrichfaces/">

                      <h:outputLink value="http://labs.jboss.com/jbossrichfaces/">

                            <h:outputText value="RichFaces Home Page"></h:outputText>

                      </h:outputLink>

                </rich:panelMenuItem>

                ...

          </rich:panelMenu>

    ...

There are two icon-related attributes. The "icon" attribute defines an icon. The "iconDisabled" attribute defines an icon for a disabled item.

Default icons are shown on the picture below:

Figure 6.222. Default icons

Here is an example:

Example:

    ...

          <rich:panelMenu>

                ...

                <rich:panelMenuItem ="Item 1.1" icon="chevronUp" />

                ...

          </rich:panelMenu>

    ...

As the result the picture is shown below:

Figure 6.223. Using an "icon" attribute

It's also possible to define a path to the icon. Simple code is placed below.

    ...

          <rich:panelMenu>

                ...

                <rich:panelMenuItem ="Item 1.1" icon="\images\img1.png" />

                ...

          </rich:panelMenu>

    ...

Information about the "process" attribute usage you can find here.

### 6.75.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:panelMenuItem> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:panelMenuItem> component

### 6.75.7. Skin Parameters Redefinition

Table 6.384. Skin parameters redefinition for a table element of the first level item

Skin parameters | CSS properties
--- | ---
generalFamilyFont | font-family

### 6.75.8. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.224. Classes names

Figure 6.225. Classes names

Table 6.386. Classes names that define the first level items

Class name | Description
--- | ---
rich-pmenu-top-item | Defines styles for a top panel menu item
rich-pmenu-top-item-icon | Defines styles for a top panel menu item icon
rich-pmenu-top-item-label | Defines styles for a top panel menu item label

Table 6.387. Classes names that define the second and lower level items

Class name | Description
--- | ---
rich-pmenu-item | Defines styles for a panel menu item
rich-pmenu-item-icon | Defines styles for a panel menu item icon
rich-pmenu-item-label | Defines styles for a panel menu item label

Table 6.388. Classes names that define items state

Class name | Description
--- | ---
rich-pmenu-item-selected | Defines styles for a panel menu selected item
rich-pmenu-disabled-element | Defines styles for a disabled panel menu item
rich-pmenu-hovered-element | Defines styles for a hovered panel menu item

In order to redefine styles for all <rich:panelMenuItem> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-pmenu-hovered-element {

      background-color: #ff7800;

    }

    ...

This is a result:

Figure 6.226. Redefinition styles with predefined classes

In the example a hovered element background color was changed.

Also it's possible to change styles of particular <rich:panelMenuItem> component. In this case you should create own style classes and use them in corresponding <rich:panelMenuItem> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass {

            color: #a0a0a0;

    }

    ...

The "disabledClass" attribute for <rich:panelMenuItem> is defined as it's shown in the example below:

Example:

    <rich:panelMenuItem ... disabledClass="myClass"/>

This is a result:

Figure 6.227. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the text color for disabled item was changed.

### 6.76.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:pickList value="#{pickBean.targetValues}">

            <f:selectItem itemValue="Bentley" itemLabel="Bentley"/>

            <f:selectItems value="#{pickBean.sourceValues}"/>

    </rich:pickList>

    ...

### 6.76.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPickList;

    ...

    HtmlPickList myPickList = new HtmlPickList();

    ...

### 6.76.5. Details of Usage

The <rich:pickList> component consists of

- 2 item lists. Every item has three different representations: common, selected, active. Combination of these states is possible.

- Move controls set is a set of controls, which performs moving items between lists.

The "value" attribute is the initial value of this component.

The <f:selectItem /> or <f:selectItems /> facets are used to define the values of a source list.

Example:

    ...

    <rich:pickList value="#{pickBean.listValues}">

            <f:selectItem itemValue="Bentley" itemLabel="Bentley"/>

            <f:selectItem itemValue="Audi" itemLabel="Audi"/>

            <f:selectItems value="#{pickBean.sourceList}"/>

    </rich:pickList>

    ...

The "switchByClick" attribute provides an option to copy and remove items between lists by one click. Default value of this attribute is "false", so you need a double click to copy, remove items from one list to another.

Lables of the move controls can be defined with "copyAllControlLabel" , "copyControlLabel" , "removeControlLabel" , "removeAllControlLabel" attributes.

Example:

    ...

    <rich:pickList copyAllControlLabel = "#{pickBean.copyAllLabel}" copyControlLabel = "#{pickBean.copyLabel}" removeControlLabel = "#{pickBean.removeLabel}"

    removeAllControlLabel ="#{pickBean.removeAllLabel}" value="#{pickBean.listValues}">

            <f:selectItem itemValue="Bentley" itemLabel="Bentley"/>

            <f:selectItem itemValue="Audi" itemLabel="Audi"/>

            <f:selectItems value="#{pickBean.sourceList}"/>

    </rich:pickList>

    ...

If you don't want to display labels on the buttons you need to set "showButtonsLabel" to "false".

Figure 6.229. Move control buttons without labels

With the help of "moveControlsVerticalAlign" attribute you can align move controls vertically.

The possible value for "moveControlsVerticalAlign" are "top", "bottom" and "center" (default value).

The <rich:pickList> component provides resizing of lists by using such attributes as:

- "listsHeight" defines height of the lists.

- "sourceListWidth" defines width of a source list.

- "targetListWidth" defines width of a target list.

Example:

    ...

    <rich:pickList listsHeight="#{pickBean.listsHeight}" sourceListWidth="#{pickBean.sourceListWidth}" targetListWidth="#{pickBean.targetListWidth}" value="#{pickBean.listValues}">

            <f:selectItem itemValue="Bentley" itemLabel="Bentley"/>

            <f:selectItem itemValue="Audi" itemLabel="Audi"/>

            <f:selectItems value="#{pickBean.sourceList}"/>

    </rich:pickList>

    ...

The <rich:pickList> component allows to use internationalization method to redefine and localize the labels. You could use application resource bundle and define `RICH_PICK_LIST_COPY_ALL_LABEL`, `RICH_PICK_LIST_COPY_LABEL`, `RICH_PICK_LIST_REMOVE_ALL_LABEL`, `RICH_PICK_LIST_REMOVE_LABEL` there.

Table 6.391. Keyboard usage for elements selection

Keys and combinations | Description
--- | ---
CTRL+click | Inverts selection for an item
SHIFT+click | Selects all rows from active one to a clicked row if they differ, else select the active row. All other selections are cleared
CTRL+A | Selects all elements inside the list if some active element is already present in a list
Up, Down arrows | Changes the active and selected elements to the next or previous in a list

### 6.77.3. Creating the Component with a Page Tag

Here is a simple example of how the component can be used on a page:

Example:

    ...

    <rich:progressBar value="#{bean.incValue1}"/>

    ...

### 6.77.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.progressBar;

    ...

    HtmlProgressBar myProgressBar = new progressBar();

    ...

### 6.77.5. Details of Usage

As it was mentioned above, the <rich:progressBar> component displays the status of the ongoing process.

The <rich:progressBar> component can run in two modes: `Ajax` (default) and `Client`.

- `Ajax` - In this mode the component works the same way as <a4j:poll/> which gets the current progress value from the sever, repeating after a set time interval.

- `Client` - The current progress value in Client mode is set using JavaScript API

In order to define the mode you need to use "mode" attribute.

One of the key attributes of the component is "interval" which defines the frequency of status polling and rerenders the component when the value is updated.

Polling is active while the "enabled" attribute is "true".

Example:

    ...

    <rich:progressBar value="#{bean.incValue}" id="progrs" interval="900" enabled="true"/>

    ...

With the help of "timeout" attribute you can define the waiting time on a particular request. If a response is not received during this time the request is aborted.

Status of the process is calculated basing on values of the following attributes:

- "value" is a value binding to the current progress value

- "minValue" (default value is "0") sets minimal progress value

- "maxValue" (default value is "100") sets maximum progress value

Example:

    ...

    <rich:progressBar value="#{bean.incValue}"  minValue="50"  maxValue="400"/>

    ...

This is the result

Figure 6.235. Progress bar

There are two ways to display information on a progress bar:

- Using "label" attribute

  Example:

      ...

      <rich:progressBar value="#{bean.incValue}" id="progrs" label="#{bean.incValue}"/>

      ...

- Using any child(nested) components. One of the components that can be used is <h:outputText />

  Example:

      ...

      <rich:progressBar value="#{bean.incValue}">

          <h:outputText value="#{bean.incValue} %"/>

      </rich:progressBar>

      ...

The "progressVar" attribute defines request scoped variable that could be used for substitution purpose. This variable contains the data taken from "value" attribute. Please, study carefully the following example.

Example:

    ...

    <rich:progressBar value="#{bean.incValue1}" enabled="#{bean.enabled1}" id="progrs1" progressVar="progress">

        <h:outputText value="{progress}%"/>

    </rich:progressBar>

    ...

In the shown example "progressVar" attribute defines a variable "progress" with the value taken from "value" attribute of the <rich:progressBar> component. The "progress" variable performs substitution passing the current progress value to the "value" attribute of the <h:outputText> . This is how the current value of a progress appears on the label of <rich:progressBar> .

The <rich:progressBar> component provides 3 predefined macrosubstitution parameters:

- `{value}` contains the current value

- `{minValue}` contains min value

- `{maxValue}` contains max value

You can use them as follows:

Example:

    ...

    <rich:progressBar value="#{bean.incValue1}" minValue="400" maxValue="900">

            <h:outputText value="Min value is {minValue}, current value is {value}, max value is {maxValue}"/>

    </rich:progressBar>

    ...

This is the result:

Figure 6.236. Macrosubstitution

The "parameters" is also a special attribute which defines parameters that can be to get additional data from server (e.g. additional info about process status). All you need is to define the value of your own parameter (e.g `parameters="param:'#{bean.incValue1}'"`) and you can use it to pass the data.

Example:

    ...

    <rich:progressBar value="#{bean.incValue}" parameters="param:'#{bean.dwnlSpeed}'">

        <h:outputText value="download speed {param} KB/s"/>

    </rich:progressBar>

    ...

This is the result

Figure 6.237. Usage of parameters

The component can also employ "initial" and "complete" facets to display the states of the process: "initial" facet is displayed when the progress value is less or equal to "minValue" , and the "complete" facet is shown when the value is greater or equal to "maxValue" . Please see an example below.

Example:

    ...

    <rich:progressBar value="#{bean.incValue1}">

        <f:facet name="initial">

            <h:outputText value="Process not started"/>

        </f:facet>

        <f:facet name="complete">

            <h:outputText value="Process completed"/>

        </f:facet>

    </rich:progressBar>

     ...

Information about the "process" attribute usage you can find here.

### 6.77.6. JavaScript API

Table 6.414. JavaScript API

Function | Description
--- | ---
enable() | Begins polling for ajax mode
disable() | Stops polling for ajax mode
setValue(value) | Updates the progress of the process
setLabel(label) | Update the label for the process

### 6.77.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:progressBar> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:progressBar> component

### 6.77.8. Skin Parameters Redefinition

### 6.77.9. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.238. Classes names

Table 6.421. Classes names for the progressBar without a label

Class name | Description
--- | ---
rich-progress-bar-shell | Defines styles for a wrapper <div> element of a progressBar
rich-progress-bar-uploaded | Defines styles for the completed progress area
rich-progress-bar-height | Defines height for a progressBar
rich-progress-bar-width | Defines width for a progressBar

Table 6.422. Classes names for the progressBar with a label

Class name | Description
--- | ---
rich-progress-bar-shell-dig | Defines styles for a wrapper <div> element of a progressBar
rich-progress-bar-uploaded-dig | Defines styles for the label
rich-progress-bar-remained | Defines styles for the remained progress area
rich-progress-bar-completed | Defines styles for the completed progress area
rich-progress-bar-height-dig | Defines height for a progressBar
rich-progress-bar-width | Defines width for a progressBar

## Note:

It's necessary to define width of the component in pixels only.

In order to redefine styles for all <rich:progressBar> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-progress-bar-remained{

        background-color: #ebf3fd;

    }

    ...

This is the result:

Figure 6.239. Redefinition styles with predefined classes

In the example above background color of the remained part of progress area was changed.

It's aslo possible to change styles of a particular <rich:progressBar> component. In this case you should create own style classes and use them in corresponding <rich:progressBar> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

    background-color: #ebf3fd;

    }

    ...

The "remainClass" attribute for <rich:progressBar> is defined as it's shown in the example below:

Example:

    <rich:progressBar value="#{bean.incValue1}" styleClass="remainClass"/>

This is the result:

Figure 6.240. Modificaton of a look and feel with own classes and styleClass attributes

As it could be seen on the picture above, background color of the remained part of progress area was changed.

### 6.78.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

        <rich:scrollableDataTable value="#{dataTableScrollerBean.allCars}" var="category">

            <!--...//Set of columns and header/footer facets-->

        </rich:scrollableDataTable>

    ...

### 6.78.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlScrollableDataTable;

    ...

    HtmlScrollableDataTable myScrollableDataTable = new HtmlScrollableDataTable();

    ...

### 6.78.5. Details of Usage

The component represents on a page as a scrollable table with some fixed (non-scrollable) rows ( with header and footer) and columns. Like other tables <rich:scrollableDataTable> also has optional footer and header that could be implemented using the corresponding facets. Columns of the table are optionally resizable. Resizing is available using "drag and drop" of the column vertical borders. There is possibility to expand or collapse the columns through JS API on the client side. You can define the number of the fixed columns from the left side using attribute "frozenColCount" that is not scrolled via horizontal scroll.

There is possibility to increase component performance using attribute "hideWhenScrolling" . If attribute value is "true" data is hidden during scrolling.

It's possible to select the whole row with onclick on the row or some set of rows. Selection is optional and availability of such feature is defined on the component. There are two ways to select a few rows:

- Just clicking the columns one by one.

- Clicking some row with the SHIFT button hold. In this case all the rows starting from last selected up to clicked should be selected.

The columns provides the possibility of expanding/collapsing on the client side through the next JS API:

- `collapse(columnId)` - Performs the collapse action for the column with the corresponding id

It's possible to sort the table content after clicks on the header. The feature is optional. Every column should be pointed to the comparator method that is used for sorting the table. In case the <rich:scrollableDataTable> is already sorted by some column and the header of this column has been clicked again - the sorting is reversed.

The typical variant of using:

    ...

    <rich:scrollableDataTable value="#{modelBuilder.model}" var="issues"

                frozenColCount="1"

                first="0"

                rows="40"

                width="300px"

                height="396px">

        <rich:column width="100px">

            <f:facet name="header" >

                <h:outputText value="State"/>

            </f:facet>

            <h:outputText value="#{issues.cell1}"/>

            <f:facet name="footer">

                <h:outputText value="State"/>

            </f:facet>

        </rich:column>

        <!--...//Set of columns and header/footer facets-->

    </rich:scrollableDataTable>

    ...

The "selection" attribute allows to get the row data when using one and multi-selection rows mode.

This attribute is a reference to object to the instace of `org.richfaces.model.selection.Selection` interface, containing current collection of objects selected by you.

In the following example when you submit the form, current collection of the selected objects is placed in the object's property. Then on complete action the <rich:modalPanel> with selected data is shown.

Example:

    ...

            <h:form>

                <rich:spacer height="30" />

                <rich:scrollableDataTable rowKeyVar="rkv" frozenColCount="1" height="200px"

                    width="300px" id="carList" rows="40" columnClasses="col"

                    value="#{dataTableScrollerBean.allCars}" var="category" sortMode="single"

                    selection="#{dataTableScrollerBean.selection}">

                    <rich:column id="make">

                        <f:facet name="header"><h:outputText styleClass="headerText" value="Make" /></f:facet>

                        <h:outputText value="#{category.make}" />

                    </rich:column>

                    <rich:column id="model">

                        <f:facet name="header"><h:outputText styleClass="headerText" value="Model" /></f:facet>

                        <h:outputText value="#{category.model}" />

                    </rich:column>

                    <rich:column id="price">

                        <f:facet name="header"><h:outputText styleClass="headerText" value="Price" /></f:facet>

                        <h:outputText value="#{category.price}" />

                    </rich:column>

                    </rich:scrollableDataTable>

                <rich:spacer height="20px"/>

                <a4j:commandButton value="Show Current Selection" reRender="table"

                    action="#{dataTableScrollerBean.takeSelection}"

                    oncomplete="javascript:Richfaces.showModalPanel('panel');"/>

            </h:form>

            <rich:modalPanel id="panel" autosized="true">

                    <f:facet name="header">

                        <h:outputText value="Selected Rows"/>

                    </f:facet>

                    <f:facet name="controls">

                        <span style="cursor:pointer" onclick="javascript:Richfaces.hideModalPanel('panel')">X</span>

                    </f:facet>

                <rich:dataTable value="#{dataTableScrollerBean.selectedCars}" var="sel" id="table">

                    <rich:column>

                        <f:facet name="header"><h:outputText value="Make" /></f:facet>

                        <h:outputText value="#{sel.make}" />

                    </rich:column>

                    <rich:column id="model">

                        <f:facet name="header"><h:outputText value="Model" /></f:facet>

                        <h:outputText value="#{sel.model}" />

                    </rich:column>

                    <rich:column id="price">

                        <f:facet name="header"><h:outputText value="Price" /></f:facet>

                        <h:outputText value="#{sel.price}" />

                    </rich:column>

                    </rich:dataTable>

            </rich:modalPanel>

    ...

This is a result:

Figure 6.242. The "selection" attribute usage

Here you can find fuller example of use of this attribute with example bean.

The <rich:scrollableDataTable> component has the following extra attributes for event processing on the client:

- "onselectionchange"

- "oncomplete"

- "onRowClick"

- "onRowDblClick"

- "onRowMouseUp"

- "onRowMouseDown"

rich-sdt-row-active | Defines styles for an active row
rich-sdt-row-selected | Defines styles for a selected row
rich-sdt-column-sort-up | Defines styles for ascending sorted column
rich-sdt-column-sort-down | Defines styles for descending sorted column

In order to redefine styles for all <rich:scrollableDataTable> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-sdt-header-cell{

        font-style:italic;

    }

    ...

This is a result:

Figure 6.244. Redefinition styles with predefined classes

In the example the font style for header cell was changed.

Also it's possible to change styles of particular <rich:scrollableDataTable> component. In this case you should create own style classes and use them in corresponding <rich:scrollableDataTable> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        background-color:#ffead9;

    }

    ...

The "selectedClass" attribute for <rich:scrollableDataTable> is defined as it's shown in the example below:

Example:

    <rich:scrollableDataTable ... selectedClass="myClass"/>

This is a result:

Figure 6.245. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, background color for selected item was changed.

### 6.79.3. Creating the Component with a Page Tag

Here is a simple example as it could be used on a page:

Example:

    ...

    <rich:separator/>

    ...

### 6.79.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlSeparator;

    ...

    HtmlSeparator mySeparator = new HtmlSeparator();

    ...

### 6.79.5. Details of Usage

<rich:separator> is a simple layout component, which represents a separator stylized as a skin. Thus, the main attributes that define its style are "style" and "styleClass". In addition there are "width" and "height" attributes that should be specified in pixels. On the HTML page the component is transposed into HTML <div> tag.

The line type can be customized with the `"lineType"` parameter. For example, different line types are shown after rendering with the following initial settings `lineType="double"`and `lineType="solid"`.

Figure 6.247. Different line types of <rich:separator>

Except style attributes, there are also event definition attributes:

- "onmouseover"

- "onclick"

- "onmouseout"

- etc.

### 6.79.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method.

To redefine the appearance of all <rich:separator> components at once, you should add to your style sheets the style class used by a <rich:separator> component.

### 6.79.7. Definition of Custom Style Classes

Table 6.437. Classes names that define a component appearance

Class name | Description
--- | ---
rich-separator | Defines styles for a component appearance

In order to redefine styles for all <rich:separator> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-separator{

        background-color:#ff7700;

    }

    ...

This is a result:

Figure 6.248. Redefinition styles with predefined classes

In the example background color for separator was changed.

Also it's possible to change styles of particular <rich:separator> component. In this case you should create own style classes and use them in corresponding <rich:separator> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        background-color:#ffead9;

    }

    ...

The "styleClass" attribute for <rich:separator> is defined as it's shown in the example below:

Example:

    <rich:separator ... styleClass="myClass"/>

This is a result:

Figure 6.249. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above,background color for separator was changed.

### 6.80.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:simpleTogglePanel>

        ...

    </rich:simpleTogglePanel>

    ...

### 6.80.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlSimpleTogglePanel;

    ...

    HtmlSimpleTogglePanel myPanel = new HtmlSimpleTogglePanel();

    ...

### 6.80.5. Details of Usage

The component is a simplified version of toggle panel that initially has a defined layout as a panel with a header playing a role of a mode switching control. On a component header element, it's possible to define a label using an attribute with the same name.

Switching mode could be defined with the "switchType" attribute with three possible parameters.

- `Server` (DEFAULT)

  The common submission is performed around simpleTogglePanel and a page is completely rendered on a called panel. Only one at a time panel is uploaded onto the client side.

- `Ajax`

  AJAX form submission is performed around the panel, content of the called panel is uploaded on Ajax request and additionally specified elements in the "reRender" attribute are rendered. Only one at a time panel is uploaded on the client side.

- `Client`

  All panels are uploaded on the client side. Switching from the active to the hidden panel is performed with client JavaScript.

The <rich:simpleTogglePanel> component also has an "opened" attribute responsible for keeping a panel state. It gives an opportunity to manage state of the component from a model. If the value of this attribute is"true" the component is expanded.

- "onmouseover "

- "onclick "

- "onmouseout "

- etc.

Figure 6.251. <rich:simpleTogglePanel> states

Information about the "process" attribute usage you can find here.

### 6.80.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:simpleTooglePanel> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:simpleTooglePanel> component

rich-stglpanel-body | Defines styles for a component content

Table 6.444. Style component classes

Class name | Class description
--- | ---
styleClass | The class defines panel common style. It's used in the outside <div> element
bodyClass | applicable to panels body elements
headerClass | applicable to header elements

In order to redefine styles for all <rich:simpleTogglePanel> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-stglpanel-header{

        font-style:italic;

    }

    ...

This is a result:

Figure 6.253. Redefinition styles with predefined classes

In the example the font style for header was changed.

Also it's possible to change styles of particular <rich:simpleTogglePanel> component. In this case you should create own style classes and use them in corresponding <rich:simpleTogglePanel> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        background-color:#ffead9;

    }

    ...

The "bodyClass" attribute for <rich:simpleTogglePanel> is defined as it's shown in the example below:

Example:

    <rich:simpleTogglePanel ... bodyClass="myClass"/>

This is a result:

### 6.81.5. Details of Usage

<rich:spacer> is a simple layout component which represents a transparent spacer. Thus, the main attributes that define its style are "style" and "styleClass".

In addition, the attributes are responsible for the component size: "width" and "height".

Moreover, to add e.g. some JavaScript effects, events defined on it are used.

- "onmouseover "

- "onclick "

- "onmouseout "

- etc.

### 6.81.6. Look-and-Feel Customization

On the component generation, the framework presents a default rich-spacer class in "styleClass" of a generated component, i.e. in order to redefine appearance of all spacers at once, it's necessary to redefine this class in your own CSS (replacing in the result properties defined in a skin with your own).

To define appearance of the particular spacer, it's possible to write your own CSS classes and properties in the component style attributes ( "style", "styleClass" ) modifying component property.

### 6.81.7. Relevant Resources Links

Here you can see the example of <rich:spacer> usage and sources for the given example.

## 6.82. < rich:suggestionbox >

### 6.82.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <h:inputText value="#{bean.property}" id="suggest"/>

        <rich:suggestionbox for="suggest" suggestionAction="#{bean.autocomplete}"  var="suggest">

            <h:column>

                <h:outputText value="#{suggest.text}"/>

            </h:column>

        </rich:suggestionbBox>

    ...

Here is the `bean.autocomplete` method that returns the collection to pop up:

Example:

    public List autocomplete(Object event) {

        String pref = event.toString();

        //collecting some data that begins with "pref" letters.

            ...

            return result;

        }

### 6.82.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlSuggestionBox;

    ...

    HtmlSuggestionBox myList = new HtmlSuggestionBox();

    ...

### 6.82.5. Details of Usage

As it is shown in the example above, the main component attribute are:

- "for"

  The attribute where there is an input component which activation causes a suggestion activation

- "suggestionAction"

  is an accepting parameter of a suggestionEvent type that returns as a result a collection for rendering in a tool tip window.

- "var"

  a collection name that provides access for inputting into a table in a popup

There are also two size attributes ( "width" and "height" ) that are obligatory for the suggestion component. The attributes have initial Defaults but should be specified manually in order to be changed.

The suggestionBox component, as it is shown on the screenshot, could get any collection for an output and outputs it in a ToolTip window the same as a custom dataTable (in several columns)

    ...

        <rich:suggestionbox for="test" suggestionAction="#{bean.autocomplete}" var="cit" fetchValue="#{cit.text}">

            <h:column>

                <h:outputText value="#{cit.label}"/>

            </h:column>

            <h:column>

                <h:outputText value="#{cit.text}"/>

            </h:column>

        </rich:suggestionbox>

    ...

It looks on a page in the following way:

Figure 6.257. <rich:suggestionBox> with ToolTip window

When some string is chosen input receives the corresponding value from the second column containing `#{cit.text}`

There is also one more important attribute named "tokens" that specifies separators after which a set of some characters sequence is defined as a new prefix beginning from this separator and not from the string beginning.

Example:

    ...

        <rich:suggestionbox for="test" suggestionAction="#{bean.autocomplete}" var="cit" selfRendered="true" tokens=",">

            <h:column>

                <h:outputText value="#{cit.text}"/>

            </h:column>

        </rich:suggestionbox>

    ...

This example shows that when a city is chosen and a comma and first letter character are input, Ajax request is called again, but it submits a value starting from the last token:

Figure 6.258. <rich:suggestionBox> with chosen word

For a multiple definition use either "`,.;` " syntax as a value for tokens or link a parameter to some bean property transmitting separators collection.

The component also encompasses "layout" and "style" attributes corresponding to dataTable ones for a table appearing in popup (for additional information, read JSF Reference) and custom attribute managing AJAX requests sending (for additional information, see Ajax4JSF Project).

In addition to these attributes common for Ajax action components and limiting requests quantity and frequency, suggestionBox has one more its own attribute limiting requests (the "minChars" attribute). The attribute defines characters quantity inputted into a field after which Ajax requests are called to perform suggestion.

There is possibility to define what be shown if the autocomplete returns empty list. Attribute "nothingLabel" or facet with the same name could be used for it.

Example:

    ...

        <rich:suggestionbox nothingLabel="Empty" for="test" suggestionAction="#{bean.autocomplete}" var="cit">

            <h:column>

                <h:outputText value="#{cit.text}"/>

            </h:column>

        </rich:suggestionbox>

    ...

Example:

    ...

    <rich:suggestionbox for="test" suggestionAction="#{bean.autocomplete}" var="cit">

        <f:facet name="nothingLabel">

            <h:outputText value="Empty"/>

        </f:facet>

        <h:column>

            <h:outputText value="#{cit.text}"/>

        </h:column>

    </rich:suggestionbox>

    ...

It looks on a page in the following way:

Figure 6.259. <rich:suggestionBox> with empty list

There is such feature in <rich:suggestionBox> component as object selection. If you want that selected item has been represented as object, you could set to "true" the value for "usingSuggestObjects" attribute, "false" value means that selected item represents as string.

Example:

    ...

    <rich:suggestionbox for="test" suggestionAction="#{bean.autocomplete}" var="cit" usingSuggestObjects="true">

            <h:column>

                    <h:outputText value="#{cit.text}"/>

            </h:column>

    </rich:suggestionbox>

    ...

### 6.82.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:suggestionBox> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:suggestionBox> component

### 6.82.9. Definition of Custom Style Classes

Figure 6.260. Classes names

On the screenshot, there are classes names defining specified elements.

Table 6.454. Classes names that define a suggestionBox

Class name | Description
--- | ---
rich-sb-common-container | Defines styles for a wrapper <div> element of a suggestion container
rich-sb-ext-decor-1 | Defines styles for the first wrapper <div> element of a suggestion box exterior
rich-sb-ext-decor-2 | Defines styles for the second wrapper <div> element of a suggestion box exterior
rich-sb-ext-decor-3 | Defines styles for the third wrapper <div> element of a suggestion box exterior
rich-sb-overflow | Defines styles for a wrapper <div> element
rich-sb-int-decor-table | Defines styles for a suggestion box table
rich-sb-int | Defines the styles for a suggestion box table rows (tr)
rich-sb-cell-padding | Defines the styles for suggestion box table cells (td)
rich-sb-int-sel | Defines styles for a selected row
rich-sb-shadow | Defines styles for a suggestion boxshadow

In order to redefine styles for all <rich:suggestionBox> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-sb-int{

            font-weight:bold;

    }

    ...

This is a result:

Figure 6.261. Redefinition styles with predefined classes

In the example the font weight for rows was changed.

Also it's possible to change styles of particular <rich:suggestionBox> component. In this case you should create own style classes and use them in corresponding <rich:suggestionBox> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            background-color:#f0ddcd;

    }

    ...

The "selectedClass" attribute for <rich:suggestionBox> is defined as it's shown in the example below:

Example:

    <rich:suggestionbox ... selectedClass="myClass"/>

This is a result:

Figure 6.262. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above,background color for selected item was changed.

### 6.83.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <rich:tabPanel>

            <!--//Set of Tabs inside-->

            <rich:tab>

                ...

            </rich:tab>

        </rich:tabPanel>

    ...

### 6.83.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmltabPanel;

    ...

    HtmltabPanel mytabPanel = new HtmltabPanel();

    ...

### 6.83.5. Details of Usage

As it was mentioned above, tabPanel groups content on panels and performs switching from one to another. Hence, modes of switching between panels are described first of all.

## Note:

All tabPanels should be wrapped into a form element so as content is correctly submitted inside. If a form is placed into each tab, the Action elements of Tab controls appear to be out of the form and content submission inside the panels could be performed only for Action components inside tabs.

Switching mode could be chosen with the tabPanel attribute "mode" with three possible parameters.

- `Server` (DEFAULT)

  The common submission is performed around tabPanel and a page is completely rendered on a called panel. Only one at a time tabPanel is uploaded onto the client side.

- `Ajax`

  AJAX form submission is performed around the tabPanel, content of the called tabPanel is uploaded on Ajax request and additionally specified elements in the "reRender" attribute are rendered. Only one at a time tabPanel is uploaded on the client.

- `Client`

  All tabPanels are uploaded on the client side. The switching from the active to the hidden panel is performed with client JavaScript.

As a result, the tabPanel is switched to the second tab according to the action returning outcome for moving onto another page and switching from the second to the first tab is performed.

There is also the "selectedTab" attribute. The attribute keeps an active tab name; therefore, an active tabPanel could be changed with setting a name of the necessary tab to this attribute.

There is also the "headerAlignment" attribute responsible for rendering of tabPanel components. The attribute has several values: "left" (Default), "right", "center", which specify Tabs components location on the top of the tabPanel.

Example:

    ...

        <rich:tabPanel width="40%" headerAlignment="right">

            <rich:tab label="Canon">

                ...

            </rich:tab>

            <rich:tab label="Nikon">

                ...

            </rich:tab>

            <rich:tab label="Olympus">

                ...

            </rich:tab>

        </rich:tabPanel>

    ...

Figure 6.264. <rich:tabPanel> with right aligned tabs

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"`, {2} for `"ShortConverter.SHORT"`.

Except the specific attributes, the component has all necessary attributes for JavaScript events definition.

- "onmouseover"

- "onmouseout"

- etc.

### 6.83.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:tabPanel> components at once:

rich-tabhdr-cell-disabled | Defines styles for an internal element of a disabled label

In order to redefine styles for all <rich:tabPanel> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above) and define necessary properties in them. An example is placed below:

Example:

    ...

    .rich-tabhdr-cell-active{

        font-weight: bold;

    }

    ...

This is a result:

Figure 6.266. Redefinition styles with predefined classes

In the example a tab active font weight and text color were changed.

Also it's possible to change styles of particular <rich:tabPanel> component. In this case you should create own style classes and use them in corresponding <rich:tabPanel> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

           font-style: italic;

    }

    ...

The "styleClass" attribute for <rich:tabPanel> is defined as it's shown in the example below:

Example:

    <rich:tabPanel ... activeTabClass="myClass"/>

This is a result:

### 6.84.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <rich:tabPanel>

            <!--Set of Tabs inside-->

                <rich:tab>

                    ...

                </rich:tab>

        </rich:tabPanel>

    ...

### 6.84.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlTab;

    ...

    HtmlTab myTab = new HtmlTab();

    ...

### 6.84.5. Details of Usage

The main component function is to define a content group that is rendered and processed when the tab is active, i.e. click on a tab causes switching onto a tab containing content corresponded to this tab.

The "label" attribute defines text to be represented. If you can use the "label" facet, you can even not use the "label" attribute.

Example:

    ...

        <rich:tab>

            <f:facet name="label">

                <h:graphicImage value="/images/img1.png"/>

            </f:facet>

            ...

            <!--Any Content inside-->

            ...

        </rich:tab>

    ...

A marker on a tab header defined with the "label" attribute. Moreover, each tab could be disabled (switching on this tab is impossible) with the "disable" attribute.

Example:

    ...

        <rich:tabPanel width="20%">

            <tabs:tab  label="Canon">

            <h:outputText value="Canon EOS Digital Rebel XT" />

                  ...

          </tabs:tab>

          <tabs:tab  label="Nikon">

              <h:outputText value="Nikon D70s" />

                 ...

            </tabs:tab>

            <tabs:tab label="Olympus">

                <h:outputText value="Olympus EVOLT E-500" />

                    ...

                </tabs:tab>

                <tabs:tab disabled="true" name="disabled" label="Disabled"/>

        </rich:tabPanel>

    ...

With this example it's possible to generate the tab panel with the last disabled and three active tabs (see the picture).

Figure 6.269. <rich:tabPanel> with disabled <rich:tab>

Switching mode could be defined not only for the whole panel tab, but also for each particular tab, i.e. switching onto one tab could be performed right on the client with the corresponding JavaScript and onto another tab with an Ajax request on the server. Tab switching modes are the same as tabPanel ones.

Each tab also has an attribute name (alias for "id" attribute). Using this attribute value it's possible e.g. to set an active tab on a model level specifying this name in the corresponding attribute of the whole tab.

Except the specific component attributes it has all necessary attributes for JavaScript event definition.

- "onmouseover"

- "onmouseout"

- etc.

Some event could be performed on the tab which has been entered/left using "ontabenter" / "ontableave" attributes. See the example below.

Example:

    ...

        <rich:tabPanel>

            <rich:tab label="Tab1" ontabenter="alert()">

                ...

            </rich:tab>

            ...

        </rich:tabPanel>

    ...

The following example shows how on the client side to get the names of `entered`/`left` tabs.

    ontabenter="alert(leftTabName)"

Information about the "process" attribute usage you can find here.

### 6.84.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

## Note:

A panel appearance and content is defined with a tab panel i.e. on the tab level it's possible to define only an appearance of this tab header.

There are two ways to redefine the appearance of all <rich:tab> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:tab> component

Class name | Description
--- | ---
rich-tab-active | Defines styles for an active tab
rich-tab-inactive | Defines styles for an inactive tab
rich-tab-disabled | Defines styles for a disabled tab

In order to redefine styles for all <rich:tab> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-tab-header{

            font-weight: bold;

    }

    ...

This is a result:

Figure 6.271. Redefinition styles with predefined classes

In the example a header font weight was changed.

Also it's possible to change styles of particular <rich:tab> component. In this case you should create own style classes and use them in corresponding <rich:tab> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            border-color: #5d9ffc;

    }

The "styleClass" attribute for <rich:tab> is defined as it's shown in the example below:

Example:

    <rich:tab ... styleClass="myClass"/>

This is a result:

### 6.85.3. Creating the Component with a Page Tag

Here is a simple example as it could be used in a page:

Example:

    ...

        <rich:togglePanel>

            <f:facet name="first">

                ...

            </f:facet>

            <f:facet name="second">

                ...

            </f:facet>

                ...

        </rich:togglePanel>

        ...

        <!--//Set of the toggleControls somewhere on a page.-->

    ...

### 6.85.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmltogglePanel;

    ...

    HtmltogglePanel myPanel = new HtmltogglePanel();

    ...

### 6.85.5. Details of Usage

As it was mentioned above, togglePanel splits content into named facets that become rendered and processed when a click performed on controls linked to this togglePanel (either switched on the client or send requests on the server for switching).

The initial component state is defined with "initialState" attribute, where a facet name that is shown at first is defined.

## Note:

It's also possible to define an "empty" facet to implement the functionality as drop-down panels have and make the facet active when no content is required to be rendered.

Switching mode could be defined with the "switchType" attribute with three possible parameters:

- `Server` (DEFAULT)

  The common submission is performed around togglePanel and a page is completely rendered on a called panel. Only one at a time the panel is uploaded onto the client side.

- `Ajax`

  AJAX form submission is performed around the panel, content of the called panel is uploaded on an Ajax request and additionally specified elements in the "reRender" attribute are rendered. Only one at a time the panel is uploaded on the client side.

- `Client`

  All panels are uploaded on the client side. The switching from the active to the hidden panel is performed with client JavaScript.

"Facets" switching order could be defined on the side of <rich:toggleControl> component or on the panel. On the side of the togglePanel it's possible to define facets switching order with the "stateOrder" attribute. The facets names are enumerated in such an order that they are rendered when a control is clicked, as it's not defined where to switch beforehand.

Example:

    ...

        <rich:togglePanel id="panel" initialState="panelB" switchType="client"

                            stateOrder="panelA,panelB,panelC">

            <f:facet name="panelA">

                ...

            </f:facet>

            <f:facet name="panelB">

                ...

            </f:facet>

            <f:facet name="panelC">

                ...

            </f:facet>

        </rich:togglePanel>

        <rich:toggleControl for="panel" value="Switch"/>

    ...

The example shows a togglePanel initial state when the second facet (`panelB`) is rendered and successive switching from the first to the second happens.

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"`, {2} for `"ShortConverter.SHORT"`.

### 6.85.6. Look-and-Feel Customization

The component doesn't have its own representation rendering only content of its facets, thus all look and feel is set only for content.

### 6.85.7. Definition of Custom Style Classes

Table 6.471. Classes names that define a component appearance

Class name | Description
--- | ---
rich-toggle-panel | Defines styles for all component
rich-tglctrl | Defines styles for a toggle control

In order to redefine styles for all <rich:togglePanel> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-toggle-panel{

        font-style:italic;

    }

    ...

This is a result:

Figure 6.274. Redefinition styles with predefined classes

In the example the font style for output text was changed.

Also it's possible to change styles of particular <rich:togglePanel> component. In this case you should create own style classes and use them in corresponding <rich:togglePanel> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        background-color:#bed6f8;

    }

    ...

The "styleClass" attribute for <rich:togglePanel> is defined as it's shown in the example below:

Example:

    <rich:togglePanel ... styleClass="myClass"/>

This is a result:

Figure 6.275. Redefinition styles with own classes and "styleClass" attributes

As it could be seen on the picture above, background color for panel was changed.

### 6.85.8. Relevant Resources Links

Here you can see the example of <rich:togglePanel> usage and sources for the given example.

## 6.86. < rich:toggleControl >

### 6.86.1. Description

A link type control for switching between togglePanel facets. Target Panel is specified with "for" attribute. It can be located inside or outside the togglePanel. As the result of switching between facets previous facet is hidden and another one (specified with "switchToState" or panel "stateOrder" attributes) is shown.

Figure 6.276. <rich:toggleControl> component

### 6.86.2. Key Features

- Highly customizable look and feel

- Can be located anywhere in a page layout

- Switching is provided in the three modes

  - `Server`

  - `Client`

  - `Ajax`

### 6.86.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <rich:toggleControl for="panel"/>

            ...

            <rich:togglePanel id="panel" stateOrder="[facets order to be switched]">

                <!--//Set of Facets-->

            </rich:togglePanel>

    ...

### 6.86.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlToggleControl;

    ...

    HtmlToggleControl myControl = new HtmlToggleControl();

    ...

### 6.86.5. Details of Usage

As it was mentioned above, the control could be in any place in layout and linked to a switching panel that is managed with "for" attribute (in the "for" attribute the full component "id" is specified according to naming containers).

The togglePanel could be also switched from the side of the control instead of being strictly defined in "switchOrder" attribute of <rich:togglePanel>.

Example:

    ...

        <rich:togglePanel id="panel" initialState="empty" switchType="client">

            <f:facet name="first">

                <h:panelGroup>

                    <rich:toggleControl for="helloForm:panel" value="Empty" switchToState="empty"/>

                    <rich:toggleControl for="helloForm:panel" value=" Second" switchToState="second"/>

                    ...//Some Content

                </h:panelGroup>

            </f:facet>

        <f:facet name="second">

                <h:panelGroup>

                    <rich:toggleControl for="helloForm:panel" value="Empty" switchToState="empty"/>

                    <rich:toggleControl for="helloForm:panel" value=" first" switchToState="first"/>

                    ...//Some Content

                </h:panelGroup>

            </f:facet>

            <f:facet name="empty">

                <h:panelGroup>

                    <rich:toggleControl for="helloForm:panel" value="first" switchToState="first"/>

                    <rich:toggleControl for="helloForm:panel" value=" second" switchToState="second"/>

                </h:panelGroup>

            </f:facet>

        </rich:togglePanel>

    ...

In this example the switching is performed on facets specified in the "switchToState" attribute.

Information about the "process" attribute usage you can find here.

### 6.86.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method.

To redefine the appearance of all <rich:toggleControl> components at once, you should add to your style sheets style class used by a <rich:toggleControl> component.

### 6.86.7. Definition of Custom Style Classes

Table 6.474. Classes names that define a component appearance

Class name | Description
--- | ---
rich-tglctrl | Defines styles for a toggle control

In order to redefine styles for all <rich:toggleControl> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-tglctrl {

          font-family: monospace;

    }

    ...

This is a result:

Figure 6.277. Redefinition styles with predefined classes

In the example font family was changed.

Also it's possible to change styles of particular <rich:toggleControl> component. In this case you should create own style classes and use them in corresponding <rich:toggleControl> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass {

          font-style: italic;

    }

    ...

The "styleClass" attribute for <rich:toggleControl> is defined as it's shown in the example below:

Example:

    <rich:toggleControl ... styleClass="myClass"/>

This is a result:

Figure 6.278. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style was changed.

### 6.87.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <rich:toolBar>

            <!--//...Set of action or other JSF components-->

        </rich:toolBar>

    ...

### 6.87.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlToolBar;

    ...

    HtmlToolBar myToolBar = new HtmlToolBar();

    ...

### 6.87.5. Details of Usage

A toolBar is a wrapper component that facilitates creation of menu and tool bars. All components defined inside are located on a stylized bar with possibility to group, arrange on the both bar sides, and place predefined separators between them.

Grouping and an input side definition is described for toolBarGroup that defines this functionality.

Separators are located between components with the help of the "itemSeparator" attribute with four predefined values:

- "none"

- "line"

- "square"

- "disc"

For example, when setting a separator of a disc type, the following result is produced:

Figure 6.280. <rich:toolBar> with a "disc" separator

Moreover, for toolBar style "width" and "height" attributes are placed above all.

A custom separator can be added with the help of "itemSeparator" facet.

Example:

    ...

    <f:facet name="itemSeparator">

        <rich:separator width="2" height="14" />

    </f:facet>

    ...

Custom separator can be also specified by URL to the separator image in the attribute "itemSeparator" of the <rich:toolBar> .

Example:

    ...

    <rich:toolBar id="toolBar" width="#{bean.width}" height="#{bean.height}" itemSeparator="/images/separator_img.jpg"/>

    ...

This is a result:

Figure 6.281. <rich:toolBar> with "itemSeparator" attribute.

As it could be seen in the picture above, the image for itemSeparator was changed.

### 6.87.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:toolBar> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:toolBar> component

### 6.87.7. Skin Parameters Redefinition

Class name | Description
--- | ---
rich-toolbar | Defines styles for a toolbar element
rich-toolbar-item | Defines styles for a toolbar item

Figure 6.282. Classes names

In order to redefine styles for all <rich:toolBar> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-toolbar-item{

        font-weight:bold;

    }

    ...

This is a result:

Figure 6.283. Redefinition styles with predefined classes

In the example font weight for items was changed.

Also it's possible to change styles of particular <rich:toolBar> component. In this case you should create own style classes and use them in corresponding <rich:toolBar> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-style:italic;

        font-weight:bold;

    }

    ...

The "styleClass" attribute for <rich:toolBar> is defined as it's shown in the example below:

Example:

    <rich:toolBar ... styleClass="myClass"/>

This is a result:

Figure 6.284. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above,the font style and the font weight for items was changed.

The component also has the standard attributes "style" and "styleClass" that could redefine an appearance of a particular component variants.

### 6.88.5. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlToolBarGroup;

    ...

    HtmlToolBarGroup myToolBarGroup = new HtmlToolBarGroup();

    ...

### 6.88.6. Details of Usage

A toolBarGroup is a wrapper component that groups toolBar content and facilitates creation of menu and tool bars. All components defined inside are located on a stylized bar with a possibility to group, arrange on the both bar sides, and place predefined separators between them.

Separators are located between components with the help of the "itemSeparator" attribute with four predefined values:

- "none"

- "line"

- "square"

- "disc"

To control the group location inside, use the "location" attribute with "left" (DEFAULT) and "right" values.

Example:

    ...

        <rich:toolBar itemSeparator="disc" width="500">

            <rich:toolBarGroup itemSeparator="line">

                <h:commandLink value="Command 1.1"/>

                <h:commandLink value="Command 2.1"/>

            </rich:toolBarGroup>

            <rich:toolBarGroup itemSeparator="line" location="right">

                <h:commandLink value="Command 1.2"/>

                <h:commandLink value="Command 2.2"/>

            </rich:toolBarGroup>

        </rich:toolBar>

    ...

The code result is the following:

Figure 6.286. Stylized <rich:toolbarGroup> with "location" , "itemSeparator" attributes

### 6.88.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:toolBarGroup> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:toolBarGroup> component

### 6.88.8. Definition of Custom Style Classes

It's possible to change styles of particular <rich:toolBarGroup> component. In this case you should create own style classes and use them in corresponding <rich:toolBarGroup> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            font-style: italic;

    }

    ...

The "styleClass" attribute for <rich:toolBarGroup> is defined as it's shown in the example below:

Example:

    <rich:toolBarGroup ... styleClass="myClass"/>

This is a result:

Figure 6.287. Redefinition styles with own classes and "styleClass" attributes

As it could be seen on the picture above,font style for first toolBarGroup was changed.

Figure 6.288. <rich:toolTip> component

### 6.89.2. Key Features

- Highly customizable look and feel

- Different ways of data loading to toolTip

- Disablement support

Table 6.482. rich : toolTip attributes

### 6.89.3. Creating the Component with a Page Tag

To create the simplest variant of <rich:toolTip> component on a page, use the following syntax:

Example:

    ...

    <rich:panel>

        <rich:toolTip value="toolTip content"/>

    </rich:panel>

    ...

### 6.89.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmltoolTip;

    ...

    HtmltoolTip mytoolTip = new  HtmltoolTip();

    ...

### 6.89.5. Details of Usage

To specify text information, labeled on a <rich:toolTip> , use "value" attribute. Images, links, buttons and other RichFaces components also may be put and composed inside <rich:toolTip> . Text, specified between tooltip's start and end tags will be rendered in browser as simple text. <rich:toolTip> borders stretch to enclose it contents.

There are three ways to attach a <rich:toolTip> to a page element. One of them uses nesting (this way is shown on example above). In such cases <rich:toolTip> is attached to the parent component by default.

## Note:

It is recommended to specify "id" for parent page element to ensure tooltip's correct work.

## Note:

If parent component contains more than one child, it is recommended to define <rich:toolTip> as the last one.

<rich:toolTip> may be attached to a page element by the use of "for" attribute. In this case a <rich:toolTip> may be defined separately from a page element it is applied to. "id" for page element is necessary (see the example below).

Example:

    ...

    <rich:panel id="panelId">

    ...

    </rich:panel>

    <rich:toolTip value="This is a tooltip content" for="panelId"/>

    ...

Because HTML elements are not presented in components tree built by facelets, use the attribute "for" with HTML elements as shown in example below.

Example:

    ...

    <div id="elementId">

          <rich:toolTip for="elementId">Using a toolTip</rich:toolTip>

          <p>The first simple example</p>

    </div>

    ...

    <div id="elementId">

          <p>The second simple example</p>

    </div>

    <rich:toolTip for="elementId">Using a toolTip</rich:toolTip>

    ...

<rich:toolTip> may also be invoked by JS API function. List of JS API functions available for <rich:toolTip> is listed below. JS API functions are defined for a page element, the <rich:toolTip> is applied to. Thus, <rich:toolTip> can be defined separately from that page element. It is necessary to specify "ids" for both and set <rich:toolTip> "attached" attribute's value to "false" (see the example below).

    ...

    <rich:panel id="paneld" onclick="#{rich:component("tooltipId")}.show();">

    ...

    </rich:panel>

    <rich:toolTip id="tooltipId" attached="false" value="This is a tooltip content"/>

    ...

The "mode" attribute is provided you to control the way of data loading to <rich:toolTip> . The component works properly in client and Ajax modes. In client mode <rich:toolTip> content is rendered once on the server and could be rerendered only via external submit. In Ajax mode <rich:toolTip> content is requested from server for every activation. For Ajax mode there is possibility to define a facet "defaultContent" , which provides default <rich:toolTip> content to be displayed, while main content is loading into the <rich:toolTip> (see the example below).

Example:

    ...

    <h:commandLink value="Simple Link" id="link">

        <rich:toolTip followMouse="true" direction="top-right" mode="ajax" value="#{bean.toolTipContent}" horizontalOffset="5"

            verticalOffset="5" layout="block">

            <f:facet name="defaultContent">

                <f:verbatim>DEFAULT TOOLTIP CONTENT</f:verbatim>

            </f:facet>

        </rich:toolTip>

    </h:commandLink>

    ...

This is the result:

Figure 6.289. <rich:toolTip> component with default content

And after <rich:toolTip> loaded it is changed to next one:

Figure 6.290. <rich:toolTip> component with loaded content

<rich:toolTip> appears attached to the corner dependent on the "direction" attribute. By default it is positioned bottom-right. <rich:toolTip> activation occurs after an event, defined on the parent component, takes into consideration the "delay" attribute or after calling JS API function `show()`. "hideEvent" attribute defines the way how <rich:toolTip> disappears. It default value is "none", so the <rich:toolTip> does not disappears. Deactivation may be set for example on mouseout event on the parent component (excepting the situation when the mouse is hovered onto the <rich:toolTip> itself) or after calling JS API function `hide()`.

By default, <rich:toolTip> appears smart positioned. But as you can see from the previous example, you can define an appearance direction via the corresponding attribute "direction" . And also it's possible to define vertical and horizontal offsets relatively to a mouse position.

Disabled <rich:toolTip> is rendered to a page as usual but JS that responds for its activation is disabled until `enable()` is called.

Moreover, to add some JavaScript effects, client events defined on it are used:

Standart:

- "onclick"

- "ondblclick"

- "onmouseout"

- "onmousemove"

- "onmouseover"

Special:

- "onshow" - Called after the tooltip is called (some element hovered) but before its request

- "oncomplete" - Called just after the tooltip is shown

- "onhide" - Called after the tooltip is hidden

### 6.89.6. JavaScript API

Table 6.484. JavaScript API

Function | Description
--- | ---
show() | Shows the corresponding toolTip
hide() | Hides the corresponding toolTip
enable() | Enables the corresponding toolTip
disable() | Disables the corresponding toolTip

### 6.89.7. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:toolTip> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:toolTip> component

### 6.89.8. Skin Parameters Redefinition

Table 6.485. Skin parameters redefinition for a component

Skin parameters | CSS properties
--- | ---
tipBackgroundColor | background-color
tipBorderColor | border-color
generalSizeFont | font-size
generalFamilyFont | font-family
generalFontColor | color

### 6.89.9. Definition of Custom Style Classes

Table 6.486. Classes names that define a component appearance

Class name | Description
--- | ---
rich-tool-tip | Defines styles for a wrapper <span> or <div> element of a toolTip

It depends on <rich:toolTip> layout what a wrapper element <span> or <div> to choose.

In order to redefine styles for all <rich:toolTipl> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above) and define necessary properties in them. An example is placed below:

Example:

    ...

    .rich-tool-tip{

        background-color: #eef2f8;

        border-color: #7196c8;

    }

    ...

This is a result:

Figure 6.291. Redefinition styles with predefined classes

In the example a tool tip background color, border color and font style were changed.

Also it's possible to change styles of particular <rich:toolTipl> component. In this case you should create own style classes and use them in corresponding <rich:toolTip> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

         font-style: italic;

    }

    ...

The "styleClass" attribute for <rich:toolTip> is defined as it's shown in the example below:

Example:

    <rich:toolTip ... styleClass="myClass"/>

This is a result:

Figure 6.292. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, background color and border color of tool tip were changed.

### 6.90.3. Creating the Component with a Page Tag

There are two ways to set up a tree: 1) with <rich:recursiveTreeNodesAdaptor> or <rich:treeNodesAdaptor> 2) and without them. The first method allows to omit "value" and "var" attributes definition as follows:

Example:

    ...

    <rich:tree>

        <rich:recursiveTreeNodesAdaptor roots="#{fileSystemBean.sourceRoots}" var="item" nodes="#{item.nodes}" />

    </rich:tree>

    ...

The second way requires defining some attributes, as it's shown in the example:

Example:

    ...

    <rich:tree value="#{library.data}" var="item" >

        <rich:treeNode  icon="/images/tree/singer.png" >

            <h:outputText value="#{item.name}" />

        </rich:treeNode>

        ...

    </rich:tree>

    ...

### 6.90.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlTree;

    ...

    HtmlTree myTree = new HtmlTree();

    ...

### 6.90.5. Details of Usage

As it has been mentioned above the <rich:tree> component allows rendering any tree-like data model.

The component interacts with data model via `"TreeNode"` interface (org.richfaces.model.TreeNode) that is used for tree nodes representation. The "value" attribute of the <rich:tree> component contains a nodes structure defined in a bean property. The property keeps a structure of objects that implements `"TreeNode"` interface.

<rich:treeNode> has a property "data" (see org.richfaces.model.TreeNode). Data contained in the property is placed in a request scope variable, which name is defined with "var" attribute for the <rich:tree> component.

You can develop and use your own pattern of the `"TreeNode"` interface or use a default implementation, which is defined with a default class `"TreeNodeImpl"` (org.richfaces.model.TreeNodeImpl).

There is a `"XmlTreeDataBuilder"` class (org.richfaces.component.xml.XmlTreeDataBuilder) that allows transforming XML into structures of objects containing `"XmlNodeData"` (org.richfaces.component.xml.XmlNodeData) instances as data, which could be represented by the <rich:tree> component.

It's possible to define a visual representation of a node data model (to define a node icon) and its behavior in correspondence with the data contained in this node (with a value of the "var" attribute). The node behavior is defined by the components nested into the <rich:treeNode> (e.g. links or buttons). For these purposes you should use "nodeFace" attribute. For each tree node a value of "nodeFace" attribute is evaluated and <rich:treeNode> with a value of "type" attribute equal to a value of "nodeFace" is used for node representation. See an example below.

Example:

    ...

    <h:form>

        <rich:tree style="width:300px" value="#{library.data}" var="item" nodeFace="#{item.type}">

            <rich:treeNode type="artist" iconLeaf="/images/tree/singer.png" icon="/images/tree/singer.png">

                <h:outputText value="#{item.name}" />

            </rich:treeNode>

            <rich:treeNode type="album" iconLeaf="/images/tree/disc.png" icon="/images/tree/disc.png">

                <h:outputText value="#{item.title}" />

            </rich:treeNode>

            <rich:treeNode type="song" iconLeaf="/images/tree/song.png" icon="/images/tree/song.png">

                <h:outputText value="#{item.title}" />

            </rich:treeNode>

        </rich:tree>

    </h:form>

    ...

This is a result:

Figure 6.294. The "nodeFace" attribute usage

In the example above, when each node of data model is processed, data contained in the `"data"` property of "TreeNode" interface is assigned to a request scope variable, which name is defined with "var" attribute. The value of the "nodeFace" attribute is evaluated in correspondence with the data assigned to the "var" attribute. The corresponding <rich:treeNode> component (with a value of "type" attribute equal to a value of "nodeFace" ) is used for the node representation. For example, during data model processing, an object with a name "Chris Rea" was inserted in the "var" attribute. Then the value of "nodeFace" attribute was evaluated as `"artist"`. Thus, for the node representation the <rich:treeNode> with "type" equal to "`artist`" was used.

You can also assign an EL-expression as value of the "nodeFace" attribute. See an example below:

Example:

    nodeFace="#{data.name != 'param-value' ? 'artist' : 'album'}"

There are some essential points in a "nodeFace" attribute usage: you need to define notions for typeless and a default nodes.

The typeless node is the first <rich:treeNode> component (from all children nodes nested to the <rich:tree> component) with not defined "type" attribute and defined "rendered" attribute. The typeless node is used for representation when "nodeFace" attribute is null.

Default node has the following interior presentation:

Example:

    ...

    <h:outputText value="#{varAttributeName}">

    ...

"varAttributeName" is a value for "var" attribute.

Default node is used in the following cases:

- "nodeFace" attribute is defined, but its value isn't equal to any "type" attribute value from all children nodes;

- "nodeFace" attribute is defined and its value is equal to a value of some "type" attribute from all children nodes, but the value of "rendered" attribute for this node is "false".

There is also one thing that has to be remembered using "type" and "rendered" attributes: it's possible to define several <rich:treeNode> components with equal values of "type" attribute and different values of "rendered" attribute. It provides a possibility to define different representation styles for the same node types. In the example with artists and their albums (see above) it's possible to represent albums that are available for sale and albums that are not available. Please study the example below:

Example:

    ...

    <h:form>

        <rich:tree style="width:300px" value="#{library.data}" var="item" nodeFace="#{item.type}">

        ...

            <rich:treeNode type="album" iconLeaf="/images/tree/album.gif" icon="/images/tree/album.gif"

                          rendered="#{item.exist}">

                <h:outputText value="#{item.name}" />

            </rich:treeNode>

            <rich:treeNode type="album" iconLeaf="/images/tree/album_absent.gif" icon="/images/tree/album_absent.gif"

                          rendered="#{not item.exist}">

                <h:outputText value="#{item.name}" />

            </rich:treeNode>

        ...

        </rich:tree>

    </h:form>

    ...

This is a result of the code:

Figure 6.295. The "type" and the "rendered" attributes usage

In the example the <rich:treeNode> components has equal values of the "type" attribute. Depending on value of the "rendered" attribute the corresponding <rich:treeNode> component is selected for node representation. If an album is available for sale the value of the "rendered" for the first <rich:treeNode> component is "true", for the second one is "false". Thus, the first <rich:treeNode> is selected for node representation.

Tree node can be run in tree modes. Modes can be specified with "switchType" attribute for <rich:tree> component.

- `Ajax` (default value) - Ajax submission is used performing the functionality. Note, that for collapse/expand operations an Ajax request is sent to the server and it can cause a short delay.

- `Server` - regular form of submission request is used.

- `Client` – all operations are performed totally on the client; no interaction with a server is involved. Full page content is reloaded after every action.

The "icon" , "iconCollapsed" , "iconExpanded" , "iconLeaf" attributes set the icons' images for the component. You can also define icons using facets with the same names. If the facets are defined, the corresponding attributes are ignored and facets' content is used as icons. By default the width of a rendered facet area is 16px.

Example:

    ...

    <rich:tree value="#{library.data}" var="item">

        ...

        <f:facet name="icon">

            <h:graphicImage value="/images/tree/singer.png "/>

        </f:facet>

        <f:facet name="iconCollapsed">

            <h:graphicImage value="/images/tree/singer.png" />

        </f:facet>

        <f:facet name="iconExpanded">

            <h:graphicImage value="/images/tree/singer.png" />

        </f:facet>

        <f:facet name="iconLeaf">

            <h:graphicImage value="/images/tree/song.png" />

        </f:facet>

        ...

    </rich:tree>

    ...

The <rich: tree> component can be used together with <rich: treeNodeAdaptor> . In this case there is no need to specify the attributes "value" and "var" . Besides, visual representation shouldn't be defined right in the tree. In this case a <rich: tree> tag is applied mainly for defining common attributes such as "ajaxSubmitSelection" etc.

Information about the "process" attribute usage you can find here.

## Tip:

"rowKeyConverter" support for the <rich:tree> is pending!

### 6.90.6. Built-In Drag and Drop

Words "built-in" in this context mean, that <rich:tree> component has its own attributes, that provide drag-and-drop capability. These attributes can be divided into two groups: those ones which provide drag and those which provide drop operations (see the tables below).

Table 6.489. Drag group

Attribute Name | Description
--- | ---
dragValue | Element value drag passed into processing after a Drop event
dragListener | A listener that processes a Drag event
dragIndicator | Id of a component that is used as a drag pointer during the drag operation
dragType | Defines a drag zone type that is used for definition of a dragged element, which can be accepted by a drop zone

Table 6.490. Drop group

Attribute Name | Description
--- | ---
dropValue | Element value drop passed into processing after Drop events
dropListener | A listener that processes a Drop event.
acceptedTypes | Drag zone names are allowed to be processed with a Drop zone
typeMapping | Drag zones names mapping on the corresponding drop zone parameters

Consider drag-and-drop inside a tree. All zones, which are assumed to be dragged, must be marked. In terms of <rich:tree> these zones completely correspond to tree nodes. So, all dragging nodes should be marked with "dragType" attribute. Then, to mark zone(-s), where the dragging node could be dropped, pass the type of dragging node to the "acceptedTypes" attribute of the drop zone. It would be good to itemize, that each tree node in the <rich:tree> component’s structure has its own key. Depending on how the component is used, these keys can be generated by the component itself or can be taken from the component’s data model. Keys help to identify each node in a tree; key is what exactly being passing from one node to another in drag-and-drop operations. Finally, the method binding, that will process drag-and-drop operation, should be pointed via "dropListener" attribute of the <rich:tree> .

Chapters "6.40 <dragIndicator>" and "6.39 <dndParam>" describes how to apply visual element, that show some additional information (e.g. dragging item name) while operating with drag-and-drop.

Page code, that describes a tree with built in drag-and-drop in the way it is considered, is shown below.

Example:

    ...

    <h:form>

         <rich:tree style="width:300px" value="#{libraryAjaxTree.data}" nodeFace="#{item.type}" var="item" dragIndicator=":treeDragIndicator" dropListener="#{libraryAjaxTree.processDrop}">

              <rich:treeNode type="artist" icon="/images/tree/group.png" iconLeaf="/images/tree/group.png" acceptedTypes="album">

                   <h:outputText value="#{item.name}" />

              </rich:treeNode>

              <rich:treeNode type="album" icon="/images/tree/cd.png" iconLeaf="/images/tree/cd.png" dragType="album" acceptedTypes="song">

                   <h:outputText value="#{item.title}" />

                   <rich:dndParam name="label" type="drag" value="Album: #{item.title}" />

              </rich:treeNode>

              <rich:treeNode type="song" icon="/images/tree/music.png" iconLeaf="/images/tree/music.png" dragType="song">

                   <h:outputText value="#{item.title}" />

                   <rich:dndParam name="label" type="drag" value="Song: #{item.title}" />

              </rich:treeNode>

        </rich:tree>

    </h:form>

    ...

This code renders following tree:

Figure 6.296. Drag-and-drop operations

### 6.90.7. Events handling

Listeners classes that process events on the server side are defined with the help of:

- changeExpandListener processes expand/collapse event of a treeNode

- dropListener processes a Drop event

- dragListener processes a Drag event

- nodeSelectListener is called during request sending on a node selecting event (if request sending on this event is defined)

Listener methods can be defined using the following attributes or using nested tags.

Client event attributes are:

- "onexpand" is a script expression to invoke when a node is expanded

- "oncollapse" is a script expression to invoke when a node is collapsed

- "ondragexit" is a script expression to invoke when an element passing out from a tree zone

- "ondragstart" is a script expression to invoke when dragging starts

- "ondragend" is a script expression to invoke when dragging ends (a drop event)

- "ondragenter" is a script expression to invoke when a dragged element appears on a tree

They can be used to add some JavaScript effects.

Standart HTML event attributes like "onclick" , "onmousedown" , "onmouseover" etc. can be also used. Event handlers of a <rich:tree> component capture events occured on any tree part. But event handlers of treeNode capture events occured on treeNode only, except for children events.

### 6.90.8. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:tree> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:tree> component

### 6.90.9. Skin Parameters Redefinition:

There is only one skin parameter for <rich:tree> . As it's a wrapper component for <rich:treeNode> components, look and feel customization is described in the corresponding section.

Table 6.491. Skin parameters for a wrapper element

Skin parameters | CSS properties
--- | ---
overAllBackground | background-color

### 6.90.10. Definition of Custom Style Classes

Table 6.492. Classes names that define a component appearance

Class name | Description
--- | ---
rich-tree | Defines styles for a wrapper <div> element of a tree

In order to redefine styles for all <rich:tree> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above) and define necessary properties in them. An example is placed below:

Example:

    ...

     .rich-tree{

        font-weight:bold;

    }

    ...

This is a result:

Figure 6.297. Redefinition styles with predefined classes

In the example a tree font weight was changed to bold.

Also it's possible to change styles of a particular <rich:tree> component. In this case you should create own style classes and use them in corresponding <rich:tree> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

        font-weight:bold;

    }

    ...

The "highlightedClass" attribute for <rich:tree> is defined as it's shown in the example below:

Example:

    <rich:tree ... styleClass="myClass"/>

This is a result:

Figure 6.298. Redefinition styles with own classes and styleClass attributes

As it's shown on the picture above, font weight of highlighted text node of a tree was changed to bold.

component-class | org.richfaces.component.html.HtmlTreeNode
component-family | org.richfaces.TreeNode
renderer-type | org.richfaces.TreeNodeRenderer
tag-class | org.richfaces.taglib.TreeNodeTag

### 6.91.3. Creating the Component with a Page Tag

Here is a simple example as it can be used on a page:

Example:

    ...

        <rich:tree ... faceNode="simpleNode">

            <rich:treeNode type="simpleNode">

                <!--Tree node data displaying template-->

            </rich:treeNode>

        </rich:tree>

    ...

### 6.91.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlTreeNode;

    ...

    HtmlTreeNode myPanel = new HtmlTreeNode();

    ...

### 6.91.5. Details of Usage

The "icon" , "iconCollapsed" , "iconExpanded" , "iconLeaf" attributes define icons for the component. Also you can define icons using facets with the same names. If the facets are defined, the corresponding attributes are ignored and facets contents are used as icons. The width of a rendered facet area is 16px.

    ...

        <rich:tree ...>

            ...

            <rich:treeNode ...>

                <f:facet name="icon">

                    <outputText value="A"/>

                </f:facet>

                <f:facet name="iconCollapsed">

                    <outputText value="B"/>

                </f:facet>

                <f:facet name="iconExpanded">

                    <outputText value="C"/>

                </f:facet>

                <f:facet name="iconLeaf">

                    <outputText value="D"/>

                </f:facet>

            </rich:treeNode>

            ...

        </rich:tree>

    ...

As it has been mentioned above, <rich:treeNode> defines a template for nodes rendering in a tree. Thus, during XML document rendering (a web.xml application) as a tree, the following nodes output (passed via `var="data"` on a tree) happens:

Example:

    ...

        <rich:tree ... faceNode="simpleNode" ... value="#{bean.data}" var="data">

            <rich:treeNode type="simpleNode">

                <h:outputText value="context-param:"/>

                <h:inputText value="#{data.name}"/>

            </rich:treeNode>

        </rich:tree >

    ...

Figure 6.300. Nodes output

Hence, <h:outputText /> tag outputs the `"context-param"` string and then the <h:inputText /> outputs the `data.name` element of this node.

Different nodes for rendering could be defined depending on some conditions on the tree level. Each condition represents some rendering template. To get more information on various treeNodesAdaptorAdaptor definition for nodes, see the tree component chapter.

Switching between expanded/collapsed modes is also managed on the tree level and defined in the corresponding section.

Default nodes of the tree level as well as the ones defined with the treeNodesAdaptorAdaptor component could send Ajax requests when selected with the mouse, it's managed with the "ajaxSubmitSelection" attribute (true/false).

Information about the "process" attribute usage you can find here.

### 6.91.6. Built-in Drag and Drop

The main information on Drag and Drop operations is given in the corresponding paragraph of the tree component chapter. It's only necessary to mention that each node could also be a Drag element as well as a Drop container, i.e. the container and the element have all attributes, listeners and ways of behavior similar to the ones of the <rich:draggable> and <rich:dropZone> components simultaneously.

### 6.91.7. Events Handling

Just as Drag and Drop operations it corresponds to the one described on the tree component level for a default Node.

### 6.91.8. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:treeNode> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:treeNode> component

### 6.91.9. Skin Parameters Redefinition

### 6.91.10. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.301. Classes names

Table 6.498. Classes names that define a node element

Class name | Description
--- | ---
rich-tree-node | Defines styles for a tree node
rich-tree-node-handleicon | Defines styles for a tree node handleicon
rich-tree-node-children | Defines styles for all tree node subnodes
rich-tree-node-text | Defines styles for a tree node text
rich-tree-node-icon | Defines styles for a tree node icon
rich-tree-node-icon-leaf | Defines styles for a tree node icon leaf

Table 6.499. Classes names that define states for a node element

Class name | Description
--- | ---
rich-tree-node-selected | Defines styles for a selected tree node
rich-tree-node-highlighted | Defines styles for a highlighted tree node
rich-tree-node-handleicon-collapsed | Defines styles for a collapsed tree node handleicon
rich-tree-node-handleicon-expanded | Defines styles for a expanded tree node handleicon

In order to redefine the style for all <rich:treeNode> components on a page using CSS, it's enough to create classes with the same names and define the necessary properties in them.

To change the style of particular <rich:treeNode> components define your own style classes in the corresponding <rich:treeNode> attributes.

It is also possible to change look and feel of specific <rich:treeNode> with the help of defining for them "selectedClass" and "highlightedClass" attributes by their specific classes.

### 6.92.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

        <rich:changeExpandListener type="demo.Bean"/>

    ...

### 6.92.4. Creating the Component Dynamically Using Java

Example:

    package demo;

    }

    import demo.ImplBean;

    ...

    ImplBean myListener = new ImplBean();

    ...

### 6.92.5. Details of Usage

The <rich:changeExpandListener> is used as a nested tag with <rich:tree> and <rich:treeNode> components.

Attribute "type" defines the fully qualified Java class name for the listener. This class should implement `org.richfaces.event.NodeExpandedListener` interface.

The typical variant of using:

    ...

    <rich:tree switchType="server" value="#{project.data}" var="item" nodeFace="#{item.type}">

        <rich:changeExpandListener type="demo.ListenerBean"/>

        ...

        <!-- Tree nodes -->

        ...

    </rich:tree>

    ...

Java bean source:

    package demo;

    import org.richfaces.event.NodeExpandedEvent;

    public class ListenerBean implements org.richfaces.event.NodeExpandedListener{

    ...

        public void processExpansion(NodeExpandedEvent arg0){

            //Custom Developer Code

        }

    ...

    }

    HtmlRecursiveTreeNodesAdaptor myRecursiveTreeNodesAdaptor = new HtmlRecursiveTreeNodesAdaptor();

    ...

### 6.94.5. Details of Usage

The <rich:recursiveTreeNodesAdaptor> component has a "roots" attribute that defines collection to use at the top of recursion.

The "nodes" attribute defines collection to use on another recursion levels.

The "var" attribute is used to access to the current collection element.

The <rich:recursiveTreeNodesAdaptor> component can be nested without any limitations. See the following example.

Example:

    ...

    <rich:tree adviseNodeOpened="#{treeModelBean.adviseNodeOpened}" switchType="client">

        <rich:treeNodesAdaptor id="project" nodes="#{loaderBean.projects}" var="project">

            <rich:treeNode>

                <h:commandLink action="#{project.click}" value="Project: #{project.name}" />

            </rich:treeNode>

            <rich:recursiveTreeNodesAdaptor id="dir" var="dir" root="#{project.dirs}" nodes="#{dir.directories}">

                <rich:treeNode>

                    <h:commandLink action="#{dir.click}" value="Directory: #{dir.name}" />

                </rich:treeNode>

                <rich:treeNodesAdaptor id="file" var="file" nodes="#{dir.files}">

                    <rich:treeNode>

                        <h:commandLink action="#{file.click}" value="File: #{file.name}" />

                    </rich:treeNode>

                </rich:treeNodesAdaptor>

                <rich:treeNodesAdaptor id="file1" var="file" nodes="#{dir.files}">

                    <rich:treeNode>

                        <h:commandLink action="#{file.click}" value="File1: #{file.name}" />

                    </rich:treeNode>

                </rich:treeNodesAdaptor>

                <rich:recursiveTreeNodesAdaptor id="archiveEntry" var="archiveEntry"

                    roots="#{dir.files}" nodes="#{archiveEntry.archiveEntries}"

                    includedRoot="#{archiveEntry.class.simpleName == 'ArchiveFile'}"

                    includedNode="#{archiveEntry.class.simpleName == 'ArchiveEntry'}">

                    <rich:treeNode id="archiveEntryNode">

                        <h:commandLink action="#{archiveEntry.click}" value="Archive entry: #{archiveEntry.name}" />

                    </rich:treeNode>

                </rich:recursiveTreeNodesAdaptor>

## Chapter 7. IDE Support

RichFaces support is implemented in JBoss Developer Studio 1.0.0 GA and in Jboss Tools. JBoss Developer Studio is a fully packaged IDE that provides full support for Java Server Faces, RichFaces, Facelets, Struts and other Web technologies. In addition to this, it seamlessly combines visual and source-oriented development approaches. One of the special support feature for RichFaces is that it is available as project "capabilitiy" which can be added to any existing JSF project by adding libraries and modifying configuration files as required."
