[Zope] Subclassing OrderedFolder

[Gary Godfrey]

Ok, so it says in the OrderedFolder blurb that it should be easy to set it
as a base class for other folderish objects.  I can't seem to make it
work.  From what I can tell, it seems to be getting hung up on the
NoBabelTag stuff and shows the error:

Error Type: AttributeError
Error Value: 'None' object has no attribute 'blocks'

when I try to bring up the management screen.  Does anyone have an example 
of using OrderedFolder as a base class?

Thanks,
