[Zope-dev] ZODB.POSException.ConflictError on attribute assignment

[zope-dev at rosenthaltechnologies.com]

I'm getting a ZODB.POSException.ConflictError in the following code in a
Custom Zope Product, and I'm hoping someone can enlighten me on how to
fix it.

# nd is a folder with a sub-folder "Categories
# "NDCategory" is a custom Zope product I wrote that does not have
anything called "bogus" defined.
categories = nd.Categories.objectValues('NDCategory')
for cat in categories:
        cat.bogus = []

Can anyone explain this to me?

Thank you in advance,
Brian Rosenthal
