I was working on something similar and this might get you closer
StateManagerImpl sm =
(StateManagerImpl)currentState.pcGetStateManager();
SaveFieldManager sfm = sm.getSaveFieldManager();
PersistenceCapable oldState = sfm.getState();
I believe you must also specifiy openjpa.RestoreState so that this can work ...
Hope this helps ...
