Checked it, looks good. The weird thing is I'm doing these cascaded popups all over and they seem fine except on this form. This is a modal dialog on top of a modal dialog, so this is a child EC, but the fetches are into the child EC so there shouldn't be a problem. I'll keep searching, I'll update the list when I find something. > Bad modelling. How dare you sir! :-p > Are you using inheritance and have duplicate PKs in different tables?
