I think I must have missed the begining of this one, what is it you are failing to achive? I have a hotpatch product that does what I think you are talking about, so I guess we are not talking about the same thing. Adrian... -----Original Message----- From: Morten W.

There's another reason to want to know the answer to this: the ability to hotpatch the base classes of an existing zope class instead of having to modify the source code for that class. This came up for the person who was trying to create a version of the CMF that used ZPatterns...and I don't recall hearing a solution.

Plus, it sure is a "surprise" that something that works in normal python code doesn't work in Zope! I presume this is an ExtensionClass issue, but I don't know enough to suss it out.

I'd offer $50 of merchandise at <put your favourite online store here> to anyone who fixes this issue.
