Hi ,
Thanks for you reply.
I would like to know whether it is possible to persist the parent child
entities and expect the results that i am expecting when:
1. child has a composite primary key that has a FK to the parent's table
PK : keyId + id (parent table's primary key)
2. "id" which is a FK and part of child's PK is a sequence number and is
generated only when the parent record is inserted in the DB.
3. Both keyId and id are non nullable fields of the child table.
4. when i define bi-directional relation i don't see any exceptions and there
is no insert SQL generated for the child table. but when i define only
@OneToMany in parent entity i see the parent record insert SQL and update SQL
for the child record which may be the update for the parent child relation. and
an exception soon after the update is executed.
following is the stack trace..
[SQL] update EVENT_INFO set ID=? where ID=? and keyId=?
[AbstractBatcher] preparing statement

.......
but where is the insert record for the child gone..?
Also Could you please give me the details of the bug you were refering to ..?
Thanks
