[Zope] Can't set security on file objects (bug)

Hi, I'm trying to protect some documents (binary) from being viewed. I've uploaded them as file objects, but I can't set the "view" security property from them. I get a Zope error: Error Type: AttributeError Error Value: tag I think I can achieve my goal with a protected directory, but I think this is a bug (Zope 2.1.4). Greetings, Michiel --
