Ok thanks Michael. We found a work around. We are now closing sessions once the object is retriewed from database since we don't care if it is not synchronized with fresh data. I will post another topic since it does not seem to work with inherited tables. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
