I'll have to pick this up in the morning, if I stare at this for
another minute I'm going to lose it.
I'll create a test case for you tomorrow and send it unless I just
find a rigged-work-around to get this thing out the door using a

download wicket-quickstart project
hack Index page to reproduce the problem
i dont need your entire app, just looking at the code youve sent all i need
from your app is maybe the category object, then instead of calling product
proxy create the list of cats yourself.
then zip up quickstart into a zip and attach it. that way i can download,
open and run it and see the problem myself so i can walk it in the debugger.
