hi peter,
setting an associated object works fine for me:
Query query;
Criteria crit;
Person person;
Person partner;
crit = new Criteria();
crit.addEqualTo("id", new Integer(4));
query = new QueryByCriteria(Person.class, crit);
person = (Person) broker.getObjectByQuery(query);
crit = new Criteria();
crit.addEqualTo("id", new Integer(5));
query = new QueryByCriteria(Person.class, crit);
partner = (Person) broker.getObjectByQuery(query);
person.setPartner(partner); <<< person 5 is partner of person 4
person.setGeburtsDatum(new Date());
broker.store(person);
these are some of the generated sqls :
SELECT
A0.isBoss,A0.gebDat,A0.idTest,A0.entryDate,A0.adresse,A0.idPartner,A0.name,A
0.test,A0.vorname,A0.id FROM tabPerson A0 WHERE A0.id = '4'
SELECT
A0.isBoss,A0.gebDat,A0.idTest,A0.entryDate,A0.adresse,A0.idPartner,A0.name,A
0.test,A0.vorname,A0.id FROM tabPerson A0 WHERE A0.id = '5'
UPDATE tabPerson SET vorname='M.', name='Z.', adresse='',
gebDat='2002-11-22', test='2', isBoss='true', entryDate='2002-11-22
14:19:19.718', idPartner='5', idTest='' WHERE id = '4' AND entryDate =
'2002-11-22 14:18:02.0'
btw: i use the latest from cvs, maybe you should try this as well...
