> The ChangeManager currently only supports applying component changes to the entire view.  This is accomplished via the following API:
> public void applyComponentChangesForCurrentView(FacesContext facesContext)
> I would like to have the ability to apply component changes to a specific subtree as opposed to the entire view.  This would require a new API along the lines of:
> public void applyComponentChangesForSubtree(FacesContext facesContext, NamingContainer root)
> Note that this method would operate on a subtree rooted at a NamingContainer in order to allow ChangeManager to easily filter the component changes based on id comparisons.  (SessionChangeManager already has access to scoped ids for each component change, so checking whether a particular change is applicable by examining the id should be very efficient.)
> The reason for requesting this new API is that I have cases where portions of the subtree are created dynamically at render time, after applyComponentChangesForCurrentView() has been called.  I need to be able to apply component changes directly to the newly created subtrees without re-applying the changes to the entire view.
