hi.
running the dbcook tests, from v4070 onwards i get the following
error:
Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'proxy_set'The case is somewhat strange but is working before that - a polymorphic union of concrete inheritances where the root-table is not included in the union (i.e. leafs only). If it gets included, the error goes away. i dont know, if it's the case that is too weird, i could workaround it possibly. svilen --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
