It seems like the 'advanced' tab needs 'manage_product_zclass_info' which is in Shared/DC/ZRDB/DA.py - but I'm stuffed if I can figure out how this is meant to work...

Ah, figured it out. You have to have ZClasses created that don't derive from the Persistent base classes - the ZClass interface now includes this.

Unfortunately the fix to ZClass.py:1.37 to copy manage_options from the base class fails if you create a ZClass that derives from nothing at all. I wrapped the copy operation in an if zope_object: test (not sure that this is the best approach, a better one might be to test for manage_options being there at all) and it's happier...

Can we review your diff? -Michel
