[Zope3-Users] UnpickleableError when adding object with reference

I add a Limoservice object, then inside that object add a Car; then I add a Driver (which contains a Car), and the AddForm offers a dropdown with '(no value)' and my Car object. If I select the car from the dropdown I get an error: UnpickleableError: Cannot pickle type
