--------------------------------------
Here is a test showing the problem (and documenting the desired behavior) : https://github.com/andrus/cayenne/commit/7d3ea21bcd5164b89d942562adadfe17e9d61786

> Key: CAY-2243
> URL: https://issues.apache.org/jira/browse/CAY-2243
> Project: Cayenne
> Issue Type: Bug
> Affects Versions: 3.1.1, 4.0.M4
> Reporter: Andrus Adamchik
> Priority: Minor
>
> ObjectContext.getGraphManager().unregisterObject() behaves inconsistently between ROP and regular Cayenne in regards to the object state after unregistering, and I don't think either one of the two is fully correct.
> 1. Here is the desired behavior, which seems like the most reasonable outcome - ObjectContext is set to null, persistent state - to TRANSIENT, ObjectId is preserved:
> graphManager.unregisterNode(object.getObjectId());
> verify(object, times(0)).setObjectId(null);
> verify(object).setObjectContext(null);
> verify(object).setPersistenceState(PersistenceState.TRANSIENT);
> 2. ROP Behavior:
> // succeeds
> verify(object, times(0)).setObjectId(null);
> // fails
> verify(object).setObjectContext(null);
> // fails
> verify(object).setPersistenceState(PersistenceState.TRANSIENT);
> 3. Server Behavior:
> // fails
> verify(object, times(0)).setObjectId(null);
> // succeeds
> verify(object).setObjectContext(null);
> // succeeds
> verify(object).setPersistenceState(PersistenceState.TRANSIENT);
