Tag support


Adds the AJAX functionality for those UIComponent-based component that have properties for JavaScript events. During Decoding: If a request is Ajax-performed, 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, passes it to the queueEvent() method of the component, and then appends it's reRender components IDs to a list of rendered areas. During Encoding. Doesn't encode as a component. Instead, it adds ValueBinding for a property of the parent component with the name as a value of its "event" property. As a result, when rendered, the parent component builds JavaScript code for submitting an AJAX request on this event. If the component has child UIParameter components, appends it's name/value as additional request parameters. If a parent component is an instance of UIInput and the ajaxType property is "input", submits the value of the input field, also. In this case, you can submit a single input field outside of UIForm.

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
actionExpressionfalsefalsejavax.el.MethodExpression
(signature must match void actionExpression(${prop.methodargs}))
The action method binding expression.
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
disableDefaultfalsefalsejavax.el.ValueExpression
(must evaluate to boolean)
Disable default action for target event ( append "return false;" to javascript )
eventfalsefalsejava.lang.StringName of JavaScript event property ( onclick, onchange, etc.) of parent component, for which we will build AJAX submission code
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 element to set focus after request 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
limitToListfalsefalsejavax.el.ValueExpression
(must evaluate to boolean)
If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
onbeforedomupdatefalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
JavaScript code for call before DOM has been updated on client side
oncompletefalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
JavaScript code for call after request completed on client side
onsubmitfalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
JavaScript code for call before submission of ajax event
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
requestDelayfalsefalsejavax.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
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
