well, unfortunately it is now a requirement due to various reasons.
what you should do is factor out whatever behavior out of onattach() into a
separate method, and then override that method in the subclass, that way you
dont need to override onattach() in the subclass, and even if you do you can
still call super.

onAttach() overwrites the behavior of the code in super.onAttach().
But if I don't call super.onAttach(), the flag FLAG_ATTACHING never gets
reset, and Wicket throws an exception.
