[Zope] ZClass 'UNSLICEABLE OBJECT' Error Value

[Eric Roby]

Sorry Joachim,

I misunderstood your previous response on the zope-dev listing.  I thought
it might be something I was misunderstanding about ZClasses.
I will load 2.3.2 and see if I still have that problem.  Thanks for your
response.

Eric
