I see, thanks. I missed the notify() because I override
handle_edit_action() without calling super(), and I looked at the
content interfaces for the trouble, not at the forms.

This brings the question: is it the form's responsibility, or the
container's? Why is a container any different than other content
objects?
There has to be a simple reason the parent is not notified inside
AddFormBase.add(), and I try to state it.. "within a container
interface, we can always know when it's modified. With other objects, we
cannot unless we wrap each and every exposed attribute."

It sounds right, now..  :-)
