Message I've fixed the multiplicity issues and altered the GeneratorJava class to
return Lists instead of Vectors. However, I can't seem to get the
generateVisibility method to give me the appropriate visibility. Here's
what's happening:

   - When I debug into the method I find that a call
   to Model.getFacade().isPublic(obj) is always returning true. It is being
   passed an AssociationEndImpl object, and when you get its visibility it
   returns Public. When I try to inspect the AssociationEnd all I get are a
   ton of MOF IDs, and maps and lots of useless crap but no attribute called
   visibility that I can inspect.

   - When I make a call to getName on the Association, it returns null for
   both association ends, despite the fact that one of the association ends is

My thought is that the Property panel is setting some other attribute of
the Association End to private. But I can't really confirm this. Does
anyone have any suggestions for how to proceed further?
