We never saw PersistenceState get set to MODIFIED. Confusing! Does that mean we messed up in the monitoring and should do the test again?
All we saw was 3 (committed) and 5 (hollow) Should I put a break point in the datasource delegate or what will that not show me where I am making things dirty? Why we do NOT see these updates when we override writeProperty... and why we never see the valued MODIFIED when we override setPersistenceState(). Something is not quite right. Hmmm....
