[Zope3-Users] using filter in addMenuItem

[Christophe Combelles]

I think the context of an adding view is an object providing IAdding. The 
context of the context might be the container of your object.
Try to set isNeedtoDisplay as the container's method, and maybe 
"context/context/isNeedtoDisplay" as your filter.
