Hi Rune and Jorge, thanks for your prompt replies! Rune, your Catwalk suggestion worked like a charm, thanks.
Jorge, I had already made the change you suggested to the sqlobject.txt file :( Through Catwalk I can now create objects, and see them in MySQL, but no luck through tg-admin shell. I can create one of my model objects and a TG_User object inside the *same* transaction (beginning before, committing after), and my model object is in the db, but not the TG_User! Very puzzling! I even tried changing my model to use an AutoConnectionHub instead of a PackageHub (no idea what the difference is here), but this did not help either. Regards, Mike.
