Thank you.
But:
1. The Content Page registers two user controls: "DeclarationList" and "DeclWiz".
2. The user control that you call just "The Control" (by the way, is it "DeclarationList" or"DeclWiz"?) registers "AddressSelector" and you just provided it.
3. The AddressSelector registers the Contact and, but I have no such control.
4. Summary: there are the four user controls, but you provided just two ones.
So, unfortunately, your sample is not runnable yet.
Also I think that it can be extremely simplified, but will still reproduce the problem. Probably, only a single page (without a master page) and a single user control are required to reproduce the problem.
Please simplify. The following technique should help.

Also please take some time to investigate this guide.
