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.
