Attributes
NameRequiredRequest-timeTypeDescription
actionfalsefalsejavax.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
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)
Limits JSF tree processing (decoding, conversion, validation and model updating) only to a component that sends the request. Boolean. Default value is "false".
bindingfalsefalsejavax.el.ValueExpression
(must evaluate to javax.faces.component.UIComponent)
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)
Enables/disables pushing. Default value is "true".
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.)
focusfalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
ID of an element to set focus after request is completed on client side
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 is "1000"ms (1 second).
limitToListfalsefalsejavax.el.ValueExpression
(must evaluate to boolean)
If "true", then of all AJAX-rendered on the page components only those will be updated, which ID's are passed to the "reRender" attribute of the describable component. "false"-the default value-means that all components with ajaxRendered="true" will be updated.
onbeforedomupdatefalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
The client-side script method to be called before DOM is updated
oncompletefalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
The client-side script method to be called after the request is completed
processfalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.Object)
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
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
similarityGroupingIdfalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
If there are any component requests with identical IDs then these requests will be grouped.
statusfalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
ID (in format of call UIComponent.findComponent()) of Request status component
timeoutfalsefalsejavax.el.ValueExpression
(must evaluate to int)
Timeout (in ms) for request
