OK, I now have a pk property (+ getter/setter) in my child object, and I
removed the properties for ccrId and recordNum. My composite-id element now
has a name="pk" attribute. The select still seems to work fine and I'm
getting the expected number of children.
However, when I try to save, I get the ol' foreign key violated exception:
[junit] java.sql.BatchUpdateException: ORA-00001: unique constraint
(CCTADMIN.CMCF_MPS_PK) viola
ted
I tried changing the unsaved-value to "any", "null" and "none" and none of
them worked for me.
Any ideas? If this is *supposed* to work, then maybe there's a 3rd primary
key on the CMCF_MPS table I'm not aware of.
Thanks,
Matt
