Hello zope gurus, I'm wondering if it is possible to override a method on a single instance of an object in the ZODB. My suspicion is no, but it doesn't hurt to ask. Specifically, I've tried: def userFolderDelUsers(self, names): pass from types import MethodType setattr(acl_users, 'userFolderDelUsers', MethodType(userFolderDelUsers, acl_users, acl_users.__class__)) Which works fine until the transaction gets committed, at which point it fails with "TypeError: can't pickle function objects". Which seems pretty much like a lost cause. Can you only do this at the class level? Is there an unrelated way to accomplish the same goal (overriding a method, without monkeypatching or subclassing)? Thanks for any enlightenment, Alec Mitchell
