public class PostAddToViewEvent extends ComponentSystemEvent
When an instance of this event is passed to
SystemEventListener.processEvent(javax.faces.event.SystemEvent)
orComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent)
, the listener implementation may assume that thesource
of this event instance is aUIComponent
instance and that either that instance or an ancestor of that instance was just added to the view. Therefore, the implementation may assume it is safe to callUIComponent.getParent()
,UIComponent.getClientId()
, and other methods that depend upon the component instance being added into the view.The implementation must guarantee that
Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object)
is called, immediately after anyUIComponent
instance is added to the view hierarchy except in the case whereResponseStateManager.isPostback(javax.faces.context.FacesContext)
returnstrue
at the same time asFacesContext.getCurrentPhaseId()
returnsPhaseId.RESTORE_VIEW
. When both of those conditions are met,Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object)
must not be called.The implementation must guarantee that
Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object)
is called in the following cases.Upon the initial construction of the view, when each instance is added to the view.
On a non-initial rendering of the view, if a component is added to the view by the View Declaration Language implememtation as a result of changes in evaluation result of EL expressions referenced by VDL tags such as
c:if
,ui:include
, and other tags that dynamically influence the assembly of the view.If a component is programmatically added to the view using the Java API directly. For example, user code manually adds children using
comp.getChildren().add()
, wherecomp
is aUIComponent
.
