I updated to OpenJPA 1.1.0, and I'm not getting the above exception anymore,
but its still not working 100%.
Updated example code:
em.getTransaction().begin();
TblScmpdt tblScmpdt = new TblScmpdt();
tblScmpdt.setAdmsysCde("EBSTA");
tblScmpdt.setFndCde("0001526");
tblScmpdt.setGccCde("A1526");
tblScmpdt.setPflcmnDte(new Date());
TblPdtbnfcde tblPdtbnfcde =
em.getReference(TblPdtbnfcde.class, new
Integer(13));
tblScmpdt.setPdtcdeId(tblPdtbnfcde.getTblPdtcde().getPdtcdeId());
tblScmpdt.setTblPdtcde(tblPdtbnfcde.getTblPdtcde());
//First need to save parent, this wouldn't be necessary
if the child
didn't have a composite key
tblScmpdt = em.merge(tblScmpdt);
em.flush(); //Have to flush otherwise JPA tries to
persist child before
parent
TblPdtbnf tblPdtbnf = new TblPdtbnf();
tblPdtbnf.setCmnDte(new Date());
tblPdtbnf.setTblPdtbnfcde(tblPdtbnfcde);
tblPdtbnf.setPdtbnfId(tblPdtbnfcde.getPdtbnfId());
tblPdtbnf.setTblScmpdt(tblScmpdt);
tblPdtbnf.setScmpdtId(tblScmpdt.getScmpdtId()); //this
should get done
automatically by JPA
tblScmpdt.getTblPdtbnfs().add(tblPdtbnf);
//merge again to save child(ren)
tblScmpdt = em.merge(tblScmpdt);
em.getTransaction().commit();
