      javax.faces.event.SystemEvent

              javax.faces.event.PreRemoveFromViewEvent
All Implemented Interfaces:
java.io.Serializable
public class PreRemoveFromViewEvent
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 that is about to be removed from 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.
