> 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.
