Registering Objects

Hi, 

I am using Cayenne 3.0B1. I have couple of what-ifs

1. If I try to register an already registered DataObject, will it create duplication?
2. If I create a new object Using DataContext.newObject(..), and then don't modify the newly created object. Will it create a new DB entry on commitChanges()?

I am hoping the answers to both would be no.

Regards,
Nishant

No and yes. You'll need to unregister manually

No, DataContext handles this case correctly.

Yes. The object will be committed.
