Thanks, I'll try that. I'll be demoing the app for a crowd that is more into beer than cheese, so it's an easy trick to get their attention.

Since your ShoppingCartPanel knows it going to use AJAX, its constructor may also choose to setOutputMarkupId(true) on the passed in components. BTW, is "Beer" a special kind of Norwegian cheese then?
