[Grok-dev] How do I reference a common template in the statics folder?

Thanks! But I am still missing something:

TraversalError: (<protoncms.protonworkflow.ProtonWorkflow object at  
0x3194d70>, 'macros')

I have created macros.py...

## macros.py
import grok
from zope.interface import Interface

class Master(grok.View):

...and also...


...and I have defined...

[...] metal:define-macro="admin" [...]

...and I call it with...

[...] metal:use-macro="context/@@macros/admin" [...]

I am probably missing something simple, but I am at a loss... :)

Mvh Sebastian
