in general, you get an AttributeError if you try to execute e.g. obj.foo where "obj" is an
object but the "foo" attribute doesn't exist.  in your case, the AttributeError seems to be
occurring deep down inside Zope, which makes it a bit hard to figure out exactly what
you been doing wrong (if anything).  It could be a bug in your code, or a bug in Zope,
or a bug in some module you're using.

it's probably best to post this to a Zope-specific mailing list.
