Bruce,
I was manually handling the many-to-many relationship between Bs and Cs
because the Bs were already in a one-to-many relationship with As using
"depends". With this mapping, things work fine for create(), but not for
long transaction update() or short transaction change and commit().
Ilia,
I was, in fact, using update(a) and the short transaction change the A and
commit(). In both cases, when a new C was added to the A, causing the C to
be created, create()ing an association object in C.jdoAfterCreate() causes
an error in Castor.
I am now using Datbase.setAutoStore(true) and it is working with my "toy"
application.

It has nothing to do with long transactions. He is not calling update.
If those transactions are not concurrent
it should work.

Doug,
Why are you manually handling the many-to-many u! sing a callback?
If the relationships between objects are mapped correctly, Castor
should handle it on its own.
