[Zope-CMF] portal poll: AttributeError

[Andreas Lindenblatt]

Hi List, hi Dave,

after playing a lot with the former early PTK (and giving up somewhere
in time cause I couldn't keep up with the changes :)) I wanted to give
the CMF a new chance.

Works great out of the box - and the skins really rock!
(fresh install of Zope 2.3.1, CMF1.0-Tarball, Python 1.5.2 on
Mandrake7.2) 

For better understanding what makes the CMF tick I tried to get the
portal poll up and running. 
I followed Dave's fine tutorial, and there were just two steps which
could not be completed like stated in the tutorial:
- the properties of the propertysheet with type of int required a value
(not "", I used '0')
- while adding the ZClass there's no CMF:PortalContent in the Base
Classes, I used CMFCore:PortalContent

Testing the portal poll was not successfull. After I press [Add] at 'Add
Content' -> Poll -> ID:TestPoll, I get:

Error Type: AttributeError
Error Value: PollClassProduct

I'm fairly sure I have a fundamental typo somewhere, but I can't figure
out what's wrong. Before I recheck things for a fourth time... maybe
someone with more experience has an idea where to look for this
'AttributeEror'?

Thanks in advance!
