Hi,

I have a question about initialization of reverse relations in one-to-many relations.

Example:
public class A {
Collection b;
public Collection getB() {
return b;
}
}

public class B {
A a;
public A getA() {
return a;
}
}

Now I add an instance of class B to an instance of class A:
A a=session.load((new A).getClass(),pkForA);
B b=session.load((new B).getClass(),pkForB);
a.getB().add(b);

Now I tried to get A from B:
b.getA();

It returns null!

I have to close the session (session.flush() is not enough), start a new one and load B again.
Then b.getA() returns the right object.

Can I force hibernate to set the reverse relation without using a new session?

We do not do "Managed Relations". You have to set your associations manually on both sides, just like you would have to do without using Hibernate. Just create an addB method with does that.
