Matthias, please always answer to the mailing list too, not just to my private email address. Otherwise no one can follow our discussion!
I am afraid you hit a problem of JSF 2.0. It's currently not possible to retarget a special method expression (like valueChangeListener) from one composite component to another (and, of course, also not to its children).
