Hmm. Normally there is something in the gb component to help you with
introspection problems like this. But this time I haven't found any.

I implemented this array method in a sample project and it seems to behave
quite well. I use an Observer to silently duplicate the events from the
children forms and manipulate an array in the parent form accordingly.

Even if not a new idea, I hope it helps.
