public class PostAddToViewEvent 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 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(javax.faces.context.FacesContext)
, and other
methods that depend upon the component instance being added into the
view.
The implementation must guarantee that javax.faces.application.Application#publishEvent
is called,
immediately after any UIComponent
instance is added to
the view hierarchy except in the case where ResponseStateManager.isPostback(javax.faces.context.FacesContext)
returns
true
at the same time as javax.faces.context.FacesContext#getCurrentPhaseId
returns PhaseId.RESTORE_VIEW
. When both of those
conditions are met, javax.faces.application.Application#publishEvent
must not be called.
