I won't have a chance to look at this tonight, but just a comment that is
probably irrelevant:
It's highly unusual to set #tree on a portion of a form rather than the
whole form. #tree makes $form_state['values'] have its values in a
hierarchical, rather than flat, arrangement, and it's not clear why you
would want that. It's also rather dangerous to mess with #tree when you're
form-altering, as it changes what will happen for other participants in the
form.
One thing you should make sure to check: Is ahah.js being loaded on the
page? Just check with firebug. If it's not, you may have to load it
explicitly.
