## Class PreRemoveFromViewEvent

- java.lang.Object
- - java.util.EventObject
  - - javax.faces.event.SystemEvent
    - - javax.faces.event.ComponentSystemEvent
      - - javax.faces.event.PreRemoveFromViewEvent

- All Implemented Interfaces:
    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.
