[Zope] Python product - inherittance

[Petr Knapek]

Hi Zopists,
I have a problem with inherittance of my publishable python classes.
I created in python 

classA and classB(classA)

classA has functionA and classB has functionB. In __init__.py of my
product I register only classB.

My problem is that it is not possible to call functionA of an instance
of classB. There is 'Error Type: AttributeError'. Does anybody know
where the problem is? I use Zope 2.1.6

Thanks, Petr
