## Ajax4Jsf
Tag commandLink

Renders an HTML "a" anchor element that acts like a form submit button when clicked. <br /> During Decoding: Obtains the Map from the "requestParameterMap" property of the ExternalContext. If this Map contains non null value for the "clientId" key, creates a javax.faces.event.ActionEvent around the component and passes it to the queueEvent() method of the component. If the request is Ajax-performed, adds its target IDs from the reRender property to the rendered areas list of the nesting AjaxContainer. <br /> element for decoding as described above with the parameters of the component. (PARAM_NAME and PARAM_VALUE are the names and values, respectively, of any nested UIParameter children.) The name and the value must be URLEncoded. If the "styleClass" attribute is specified, render its value as the value of the "class" attribute. Render any non-UIParameter children as normal inside of the "a" element. These will appear as the link text.

Attributes
Name | Required | Request-time | Type | Description
accesskey | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | 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 | false | false | `javax.el.MethodExpression` (signature must match `java.lang.Object 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 | false | false | `javax.el.MethodExpression` (signature must match `void actionListener(javax.faces.event.ActionEvent)`) | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | if "true", submits ONLY one field/link, instead of all form controls
binding | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | 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
charset | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The character encoding of a resource designated by this hyperlink
coords | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | 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
data | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax

eventsQueue | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | 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 | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | id of element to set focus after request completed on client side

id | false | false | `java.lang.String` | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | 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 | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | 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 | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Code describing the language used in the generated markup for this component
limitToList | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
onbeforedomupdate | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | JavaScript code for call before DOM has been updated on client side
onblur | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | 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 | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | HTML: a script expression; a pointer button is clicked
