Looking at the code, it appears that "localObject(..)" behavior for NEW objects is incorrect. It creates a HOLLOW object, and as a result an attempt is made to fetch it from the database on first access, resulting in the exception. So formally, this is a bug (or rather a gap) in localObject(..) logic. For NEW objects, it should probably do a full clone of all values and set the state to NEW. I will open a bug report.
And the workaround would be smth like this: T o1 = .. // initial new object T o1Local = context.newObject(T.class); // manually copy data from "o1" o1Local.setX(o1.getX()); o1Local.setY(o1.getY()); ... Having said that, what is a motivation for calling localObject(..) on a new object?
