Hi,
There is m-m relationship between A and B entities which are in different
models, but in same database. I can create and platen this relationship in
EOModler and got AB table as well.
AB is in the same DB and only has compound PK like A_ID and B_ID.
When I tried to do saveChanges got this error
[2009-12-15 12:6:48 NZDT] <WorkerThread0> java.lang.NullPointerException

And I found only updateObjects could has two entities's details and
insertedObjects does not print out anything.
Not sure this does not work in across models or something else need setup?
thanks
