Just a thought - could this be fixed by creating a composite-id class for my
child objects? I haven't done that yet, I'm still using:
<composite-id unsaved-value="null">
<key-property column="CCR_ID" length="22" name="ccrId"
type="long"/>
<key-property column="RECORD_NUM" length="22" name="recordNum"
type="long"/>
</composite-id>
Thanks,
Matt

Subject: Saving an object with children is not working
(grumbles after sending blank e-mail ... damn outlook)
I am getting and saving an object (with children) using the following
testscase:
public void testSaveCMCFMaster() throws Exception {
CMCFMaster c = dao.getCMCFMaster(new Long(105));
assertTrue(c != null);
// update system type to C
c.setSystemType("C");
CMCFMaster newForm = dao.saveCMCFMaster(c);
// verify that the systemType has been updated
assertTrue(newForm.getSystemType().equals("C"));
log.debug(newForm);
}
I don't want to change the PK on my parent object, nor on any children.
However, it appears that Hibernate is trying to do this:
[junit] Testcase:
testSaveCMCFMaster(com.comcast.cable.dmc.itd.cct.persistence.CMCFMasterDAOHi
be
rnateTest): Caused an ERROR
[junit] java.sql.BatchUpdateException: ORA-00001: unique constraint
(CCTADMIN.CMCF_MPS_PK) viola
ted
[junit] com.comcast.cable.dmc.itd.cct.persistence.DAOException:
java.sql.BatchUpdateException: O
RA-00001: unique constraint (CCTADMIN.CMCF_MPS_PK) violated
My DAO has simple retrieveObject and storeObject methods. In my parent's
(CMCFMaster) *.hbm.xml mapping file, I have unsaved-value="null" and all
children have unsaved-value="any". I got this idea from the FAQ. The FK
violation above is from one of the children. I tried setting all
unsaved-values to null, with no luck.
Any help is greatly appreciated.
