I'm talking about instances of ZClasses -- not the ZClasses objects themselves. Here's a cut/paste traceback:

Hmm - does this happen to _all_ of your ZClasses, or just certain ones? I have a b4 test install here and I can't reproduce this :( Perhaps it could have something to do with the particular classes you are using - can you tell me what the base classes are for one of your ZClasses that is exhibiting this behavior?
