This class is defined in the same file as this function. Is there some weird scoping issue that I am not aware of?
I would guess that the problem is that most of Zope's classes are actually ExtensionClasses. Python 1.5.1 (#0, Apr 13 1998, 20:22:04) [MSC 32 bit (Intel)] on win32 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
import Acquisition class A(Acquisition.Implicit):pass ... type(A) <extension class ExtensionClass at 00BEC778> a=A() isinstance(a,A) Traceback (innermost last): File "<stdin>", line 1, in ? TypeError: second argument must be a class
Probably the easiest solution is to add a class attribute like: class MyProduct(... isMyProduct=1 ... Then you can do things like: if hasattrib(self.aq_parent,'isMyProduct') and self.aq_parent.isMyProduct: print 'I am within another MyProduct object' Maybe there are better solutions... -Amos
