[Zope-CMF] DCWorkflow using workflow variables in guards expressions

Thanks a lot, using workflow scripts or portal_workflow both did the 
trick :)

I've just figured out that I was trying to guard worklist with object's 
workflow variables and listFilteredActionsFor always raised an exception 
because of a wrong context.
Guard expressions for transitions works just fine.
