Hi,

Is the following update code safe?
public class ParentObject {
private ChildObject childObject;
..........
}

Session s = sessionFactory.openSession();
ParentObject o1 = s.load(...);
s.close();

ChildObject o2 = new ChildObject();

if(o1.getChildObject() != null)
o2.setId(o1.getChildObject().getId());
// set some properties for newly created o2
o2.setName("new name");

o1.setChildObject(o2);

Session s1 = ...openSession();
s1.update(o1);
s1.flush();
s1.close();

TIA,

yes, it will work. I'm not sure that its very elegant, however.

I know what you mean. But we have the case when a GUI changes a lot of object's childrens data and is easier to re-create the children than traversing all the main object's graph and update each and every property for the children.

Any other suggestion?

Thanks all and particularly to Gavin ,
