public class PostAddToViewEvent
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 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
, and other
methods that depend upon the component instance being added into the
view.
The implementation must guarantee that Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object)
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 FacesContext.getCurrentPhaseId()
returns PhaseId.RESTORE_VIEW
. When both of those
conditions are met, Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object)
must not be called.
