According to the Zope Developer's Guide, when you create a ZClass by subclassing from custom python classes "your subclass's __init__ method will not be called when instances of the Z Class are created." Could someone help explain why my __init__ method is being called? Is the document just out of date? What should be the correct behavior? Also, is there a simple way of detecting from my python class's init method if it is being called within the Zope environment? I'm trying to keep my python class as non-Zope centric as possible because I use that class in other programs as well. Oh, I am using the 2.2.0a1.
