Class PostAddToViewEvent

java.lang.Object
  java.util.EventObject
      javax.faces.event.SystemEvent
          javax.faces.event.ComponentSystemEvent
              javax.faces.event.PostAddToViewEvent
All Implemented Interfaces:
java.io.Serializable
Direct Known Subclasses:
PostAddToViewNonPDLEvent
public class PostAddToViewEvent
extends ComponentSystemEvent

When an instance of this event is passed to SystemEventListener#processEvent or ComponentSystemEventListener#processEvent, the listener implementation may assume that the source of this event instance is a UIComponent 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 call UIComponent#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, java.lang.Object) is called, immediately after any UIComponent instance is added to the view hierarchy except in the case where ResponseStateManager.isPostback(javax.faces.context.FacesContext) returns true at the same time as FacesContext.getCurrentPhaseId() returns PhaseId.RESTORE_VIEW. When both of those conditions are met, Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class, java.lang.Object) must not be called.
