[Grok-dev] Generations problem

[Christian Klinger]

Hi Svenn,

i guess this is because the configure.zcml from zope.generations is not 
picked up. You can do two things:

1) Put zope.generations in your setup.py  --> install-requires.
2) add <include pacakge="zope.generations"> in your configure.zcml

I created a modified version in the "not yet released" documentation of 
grok [1]

Hope this helps
Christian
