[Zope] Renderable ZClass and Zope 2.2

[Jeff Sasmor]

Hi-
I am trying to 'update' my EventFolder product to
Zope 2.2 but a  really wierd thing is going on:

When I try to create an instance (an EventFolder, which is
subclassed from Renderable and ObjectManager) I get an
error shown in the traceback below.

There EventFolder_add method in the ZClass creates a
catalog (Catalog) which does not seem to be accessable...

yet, why is the instance being renedered at all?  It appears
as if the instance is being rendered before the transaction
is committed and therefore there's no Catalog-- this I get. But
why is the instance being rendered at all?

Is there some incompatability with Renderable and 2.2?

Confusedly,
