All:
I have an entity called "Paper" in a new model A that I would
like to relate to an entity "Employee" in an established model B.
Each of them are in their own framework project but both models use
the same database. I was hoping to make this a many to many and
flatten it. I've tried many things tonight to get this to work but
apparently I'm doing all the wrong things.
Apple's documentation seems to indicate that I should be able to
resolve type references to any models included in the model group.
I've added B eomodel to the model group section in my EOGenerate
file.
I've tried adding B.framework the build path of A.framework. This
seems to do the right things and add the join table, etc., but then
model B can't resolve type references to the entity in model A. I'm
assuming I'm just really confused about how this should work but
I've reached my limit for banging my head against it.
I'd be really grateful if anyone doing something similar could
share how they may have gotten this working.
It sounds like you have a circular dependancy: Framework A depends
on Framework B _and_ Framework B depends on Framework A. That just
won't work in Java. I think you can only do this if the
relationships are only in one direction or if both models are in the
same project.

Thanks Chuck. I actually did avoid that happening since I've only
added the existing framework to the new framework (and not the
reverse). The problem I see on my end is that everything seems to work
- relationship add, flattening, etc., but then when I clean everything
the older framework does not retain visibility to the types in the
newer one. I think I have a problem with approach. I think the best
approach may be to sub-class my user types in a third framework? I've
been putting this off. :-)
