Hi Niraj..

Please use the below statements..if you are using annotations..and want to save both parent and child as new objects..
then inside the Bean of parent class use

@OneToOne(cascade = CascadeType.ALL)
above the child member..

it works.

And if you want to keep generator as “assigned” then make sure you assign “unique” id to the object before persisting

A bit more about this issue:

Be sure your id generator option is not set to “assigned”. If your have something like that:

…

Turn class to “increment”. If you dont, it throws this issue because the parent object has not an identifier assigned yet.

See you.

Thanks Jeff for contributing. I must admit that my post is a little obsolete. I will have to update it based on current hibernate version and my knowledge on that.

I mean, a objects Set pointed by an Object.

Hello there,

For new objects, as Niraj one, I found a solution, but maybe its not the best one.

A a = new A();
B b = new B();
a.setB(b);

session.save(b);
session.save(a);

session.commit();

Well, the problem comes when I try to attach a Set to session; for each instance stored in the Set, I have to make a call to session.save(currentObject); these iteration is a really nasty way to resolve the problem, but works fine for me.

Maybe something better?

@Niraj
If A and B are new objects, solution given here is not gonna work. You may need to apply cascade for merge in mapping.
