Dear Christophe, thank you for your answer, you're right, this way i get the container object. additionally permission needs to be added for this method.
only one question remained unanswered. as i recognized zope3 collects always all addmenu items. this i assume, because the traversal exception raised for the objects where i didn't specify any filter in the addMenuItem. that means zope3 tries to check the filter expression for all container objects. i don't really understand why it is in this way. is it possible to specify a certain object where isNeedtoDisplay should be queried, or should i use a kind of sub classing solution?

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.
