Display Name | Ajax Function

Attributes
Name | Required | Request-time | Type | Description
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`) | Limits JSF tree processing (decoding, conversion, validation and model updating) only to a component that sends the request. Boolean. Default value is "false".
binding | false | false | `javax.el.ValueExpression` (must evaluate to `javax.faces.component.UIComponent`) | 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
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 an element to set focus after request is 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
limitToList | false | false | `javax.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.
name | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Name of generated JavaScript function definition
onbeforedomupdate | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The client-side script method to be called before DOM is updated
oncomplete | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The client-side script method to be called after the request is completed
process | false | false | `javax.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
reRender | false | false | `javax.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
rendered | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "false", this component is not rendered
requestDelay | false | false | `javax.el.ValueExpression` (must evaluate to `int`) | 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
similarityGroupingId | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | If there are any component requests with identical IDs then these requests will be grouped.
status | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | ID (in format of call UIComponent.findComponent()) of Request status component
timeout | false | false | `javax.el.ValueExpression` (must evaluate to `int`) | Response waiting time on a particular request. If a response is not received during this time, the request is aborted
