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

[Peter Bengtsson]

I tried to copycat the LoginDemo application from grokapps (with some
slight modifications for my usage)
But it get this error:


$ ./bin/zopectl fg

AttributeError: type object 'ISessionDataContainer' has no attribute

I'm using grok 0.12.1 here.
If I debug that sm.registeredUtilities() is I get this:
[UtilityRegistration(<LocalSiteManager ++etc++site>,
IPrincipalAnnotationUtility, '', PrincipalAnnotation, u''),
UtilityRegistration(<Loc
eManager ++etc++site>, IClientIdManager, '', broken object, u''),
UtilityRegistration(<LocalSiteManager ++etc++site>,
ISessionDataContain
', broken object, u''), UtilityRegistration(<LocalSiteManager
++etc++site>, IErrorReportingUtility, '', RootErrorReportingUtility,
u'')]

...if that means anything.
