## Ajax4jsf ( Legacy URL )
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
focus | false | false | `java.lang.String` | id of element to set focus after request completed on client side
dir | false | false | `java.lang.String` | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left)
id | false | false | `java.lang.String` | Every component may have a unique id that is automatically created if omitted
rev | false | false | `java.lang.String` | 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
bypassUpdates | false | false | `java.lang.String` | 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
limitToList | false | false | `java.lang.String` | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
style | false | false | `java.lang.String` | CSS style(s) is/are to be applied when this component is rendered
onmouseover | false | false | `java.lang.String` | HTML: a script expression; a pointer is moved onto
onkeyup | false | false | `java.lang.String` | HTML: a script expression; a key is released
tabindex | false | false | `java.lang.String` | This attribute specifies the position of the current element in the tabbing order for the current document. This value must be a number between 0 and 32767. User agents should ignore leading zeros
timeout | false | false | `java.lang.String` | Timeout ( in ms ) for request.
lang | false | false | `java.lang.String` | Code describing the language used in the generated markup for this component
actionExpression | false | false | `java.lang.String` | The action method binding expression.
onmouseout | false | false | `java.lang.String` | HTML: a script expression; a pointer is moved away
rel | false | false | `java.lang.String` | 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
onmouseup | false | false | `java.lang.String` | HTML: script expression; a pointer button is released
binding | false | false | `java.lang.String` | The attribute takes a value-binding expression for a component property of a backing bean
onmousemove | false | false | `java.lang.String` | HTML: a script expression; a pointer is moved within
coords | false | false | `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
actionListener | false | false | `java.lang.String` | MethodBinding pointing at method accepting an ActionEvent with return type void
title | false | false | `java.lang.String` | Advisory title information about markup elements generated for this component
shape | false | false | `java.lang.String` | default|rect|circle|poly [CI] This attribute specifies the shape of a region. Possible values: * default: Specifies the entire region. * rect: Define a rectangular region. * circle: Define a circular region. * poly: Define a polygonal region.
oncomplete | false | false | `java.lang.String` | JavaScript code for call after request completed on client side

rendered | false | false | `java.lang.String` | If "false", this component is not rendered
reRender | false | false | `java.lang.String` | 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
styleClass | false | false | `java.lang.String` | Corresponds to the HTML class attribute
accesskey | false | false | `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
onkeypress | false | false | `java.lang.String` | HTML: a script expression; a key is pressed and released
ondblclick | false | false | `java.lang.String` | HTML: a script expression; a pointer button is double-clicked
ajaxSingle | false | false | `java.lang.String` | if "true", submits ONLY one field/link, instead of all form controls
onblur | false | false | `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

value | false | false | `java.lang.String` | The current value for this component

onmousedown | false | false | `java.lang.String` | HTML: script expression; a pointer button is pressed down
requestDelay | false | false | `java.lang.String` | 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
eventsQueue | false | false | `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.)
