I'm using jboss 4.04ga, java 1.5.0_06, postgres 8.0.3, etc. When trying to
create Many* relationships I find the foreign keys are somehow not being
stored. The rest of the fields of the entities are persisted fine, but the
relationships do not seem to be. Strangely, OneToOne relationships seem to
turn out as expected. I suspect that I have misconfigured jboss somehow. in
my example code, table test1 has one entry, field = 1, test2 has two entries,
just as expected, only null fk_test1 fields. My entities are at the bottom of
this post, I create and persist them as so:
Test1 t1=new Test1();
ArrayList<Test2> a=new ArrayList<Test2>();
Test2 t2=new Test2();
t2.setField(1);
a.add(t2);
t2=new Test2();
t2.setField(2);
a.add(t2);
t1.setTest2s(a);
t1.setField(1);
entityManager.persist(t1);
/*
* Test1.java
*/
