Kepler

Thanks Derik I'll look into it.

This problem occurs in Kepler, but not in Vergil.

The stack trace indicates the problem is in KeplerDocApplicationSpecializer.
The issue here is that a Director is actually an Attribute, not an Entity.

I've changed KeplerDocApplicationSpecializer to ignore dealing with ports on non-entities. This seems to do the trick.
