'testb' subclasses 'testa', and wants to call 'testa.do()' in one of its dtml method. I found in zope's source codes that zope tackles this with "testb.inheritedAttribute('do')()". Yet this doesn't work in zclass dtml method. The system complains not knowing 'testb'. How to refer to its zclass name? Any other ways for a zclass to call its base class's method? Please help!
