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.

Sure, how? Maybe I'm misunderstanding? I can't stick the whole app
in there, however. Maybe I could just send you both of the entire
files (java + html)?
I've found that if I set it to 1 column, it renders w/o an exception.
If I set it to 3 columns, it bombs. When it does render, I see one
row w/ 3 items even though there are 5 items. Weird.
