Hi,
Per the Java doc of
http://javaserverfaces.java.net/nonav/docs/2.0/javadocs/javax/faces/component/UIComponent.html#getChildren(),
if I set an existing child in the returned children list, the target child
should be removed from its previous parent in both children and facet list.
While currently MyFaces seems only remove from the children list. And for
the facet map, now it only remove from the facet map. Is it a bug for
MyFaces ?
--->
getChildren
public abstract List<UIComponent> getChildren()
Return a mutable List representing the child UIComponents associated with
this component. The returned implementation must support all of the standard
and optional List methods, plus support the following additional
requirements:
The List implementation must implement the java.io.Serializable interface.
Any attempt to add a null must throw a NullPointerException
Any attempt to add an object that does not implement UIComponent must throw
a ClassCastException.
*Whenever a new child component is added, the parent property of the child
must be set to this component instance. If the parent property of the child
was already non-null, the child must first be removed from its previous
parent (where it may have been either a child or a facet).*
Whenever an existing child component is removed, the parent property of the
child must be set to null.
After the child component has been added to the view, if the following
condition is not met:
FacesContext.isPostback() returns true and
FacesContext.getCurrentPhaseId() returns PhaseId.RESTORE_VIEW
Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class,
java.lang.Object) must be called, passing PostAddToViewEvent.class as the
first argument and the newly added component as the second argument.
