[Grok-dev] Re: AttributeError: type object 'ISessionDataContainer' has no attribute 'isOrExtends'

I searched the mailing list archive and found this by PvW:

You're missing zope.app.session (and possibly zope.app.securitypolicy  
as well) which were moved to zope.session and zope.securitypolicy  
recently.  If you make your application depend explicitly on those two  
zope.app packages, it shoudl work again.

I guess it could be of some help.
