Hi, i have two Entities, "Parent" and "Child", that are linked through a bidirectional one-to-many relationship with the cascade attribute set to "all". When adding a Child object to the Parent children collection using the code below, i can't get the ID of the persisted child until i commit the transaction:

Parent p = (Parent) session.load(Parent.class, pid);
Child c = new Child();
p.addChild(c);
// "c" hasn't an ID (is always zero) 

However, when i persist a child entity by explicitly calling the session.save() method, the ID is created and set immediately, even if the transaction hasn't been committed:

Child c = new Child();
session.save(c);
// "c" has an ID

Is there a way to get the ID of the child entity immediately without calling the session.save() method?

Thanks
