actionListenerfalsefalsejavax.el.MethodExpression
(signature must match void actionListener(javax.faces.event.ActionEvent))
MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSinglefalsefalsejavax.el.ValueExpression
(must evaluate to boolean)
if "true", submits ONLY one field/link, instead of all form controls
bindingfalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdatesfalsefalsejavax.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
datafalsefalsejavax.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
enabledfalsefalsejavax.el.ValueExpression
(must evaluate to boolean)
Enable/disable pushing
eventProducerfalsefalsejavax.el.MethodExpression
(signature must match void eventProducer(java.util.EventListener))
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.
eventsQueuefalsefalsejavax.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.)

idfalsefalsejava.lang.StringEvery component may have a unique id that is automatically created if omitted
ignoreDupResponsesfalsefalsejavax.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
immediatefalsefalsejavax.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
intervalfalsefalsejavax.el.ValueExpression
(must evaluate to int)
Interval (in ms) for call push requests. Default value 1000 (1 sec)
limitToListfalsefalsejavax.el.ValueExpression
(must evaluate to boolean)

oncompletefalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
JavaScript code for call after request completed on client side
reRenderfalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.Object)
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
renderedfalsefalsejavax.el.ValueExpression
(must evaluate to boolean)
If "false", this component is not rendered
