Attributes
Name | Required | Request-time | Type | Description
action | false | false | `java.lang.String` | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by the user, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionExpression | false | false | `java.lang.String` | The action method binding expression.
actionListener | false | false | `java.lang.String` | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | false | false | `java.lang.String` | if "true", submits ONLY one field/link, instead of all form controls
binding | false | false | `java.lang.String` | The attribute takes a value-binding expression for a component property of a backing bean
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
data | false | false | `java.lang.String` | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
enabled | false | false | `java.lang.String` | Enable/disable pushing
eventProducer | false | false | `java.lang.String` | MethodBinding pointing at method accepting an PushEventListener with return type void. User bean must register this listener and send EventObject to this listener on ready.
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.)
focus | false | false | `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 | `java.lang.String` | 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 | `java.lang.String` | 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 | false | false | `java.lang.String` | Interval (in ms) for call push requests. Default value 1000 (1 sec)
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
onbeforedomupdate | false | false | `java.lang.String` | JavaScript code for call before DOM has been updated on client side
oncomplete | false | false | `java.lang.String` | JavaScript code for call after request completed on client side
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
rendered | false | false | `java.lang.String` | If "false", this component is not rendered
