Hi Chuck,
Can you describe this problem in more detail?
EOModeler is buggy. It simply does not provide a GUI way to create a
subclass from an entity in another model. You can to create a sub-
class of the entity in the original model, and then cut and paste it
where you want it. In the process, some bits are lost and you end up
cutting and pasting the relationships bit by bit. That is when it
works. When the model you want to sub-class from is in an installed
framework and uses prototypes, EOModeler will not load the prototypes
and so those don't get into the subclass and can't be cut and
pasted. So subclassing quickly becomes retyping.
The work around (such as it is) is to open the EOModel in its
original source project (if you have it), create the subclass, then
open the other project and paste in the entity. Then fix it up.
What do you do now in emacs?
Copy the entity from one model to the other, edit it, change the
name, table, class etc, set the parent. It is not too bad if you
plan ahead a bit.
And, what do you like to have in EOModeler to achieve the same
functionality?
The same functionality as it has now for inheritance within a single
model, but working for inheritance across models.
This is quite easy to do in code, it is just buggy in EOModeler (what
a shock!). :-P

Right now, I'd be pleased with even a command line tool that made
cross model inheritance easier than in emacs. And that is
probably what I will end up with. EOModeler does not seem too
pleased with cross model inheritance from an installed framework
when Xcode is not being used (even worse than before!).
