[Kevin Dangoor]

    KM|Net News is having some trouble with Zope 2.2. Specifically, when you
try to add an article, you run into this:

AttributeError: None


    I glanced through the code in UnTextIndex.py, and at first glance it
looks like self._lexicon is getting set to a Lexicon object... then,
getLexicon(self._lexicon) is called. What's odd is that it seems like
self._lexicon is supposed to be a Lexicon object, but the getLexicon method
thinks it's a string...

    Anyone got an idea on this one? The Catalog itself is created
programmatically, but was created without errors. Did anything change with
respect to index initialization between Zope 2.1 and 2.2?

Thanks,
Kevin
