All Implemented Interfaces:

java.io.Serializable

public class PreRemoveFromViewEvent
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 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.
