saveOrUpdate(Obj) question

Is there a reason saveOrUpdate(Obj) doesn't return the new Id of the object submitted? I'm often at a point where I don't know if the Entity I'm persisting is new or not, but I do need to know it's Id value after I've submitted it. I'm putting near identical versions of the following code in a lot of places:

Code:

   if (Entity.isNew()) return session.save(Entity);
   session.update(Entity);
   return Entity.get(Id);

Is there anything wrong with this line of thinking? If there's not how do I pass a request to change it on to the development team?

Actually,
I just realized what changing the method signature would do to anybody who had subclassed session class, so forget about the getting it changed part - just let me know if the code above is OK to use.

saveOrUpdate uses your unsaved-value-strategy to determine if you entity is persistent or transient.

If your whole goal is to always have your ID returned to you when persisting your objects, use saveOrUpdate but the immediately flush the session so the DML is actually sent to the DB. Then, you should be able to get the ID of the entity.

Either way, it seems as though you're doing some things different in your code compared to what you're saying you wanted to have happen.
