Class PostAddToViewEvent

java.lang.Object

java.util.EventObject

javax.faces.event.SystemEvent

javax.faces.event.ComponentSystemEvent

javax.faces.event.PostAddToViewEvent

All Implemented Interfaces:

Serializable

public class PostAddToViewEvent
extends ComponentSystemEvent

When an instance of this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), 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(javax.faces.context.FacesContext), and other methods that depend upon the component instance being added into the view.

The implementation must guarantee that javax.faces.application.Application#publishEvent 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 javax.faces.context.FacesContext#getCurrentPhaseId returns PhaseId.RESTORE_VIEW. When both of those conditions are met, javax.faces.application.Application#publishEvent must not be called.
