javax.faces.event.PostAddToViewEvent
All Implemented Interfaces: java.io.Serializable
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.
