Description Matthias Wienand CLA 2015-09-01 04:49:10 EDT 
When a transactional policy is asked for an operation to perform its changes, it should return null when no changes are to be applied, so that the undo stack does not contain empty operations.
Comment 1 Matthias Wienand CLA 2015-09-01 05:00:28 EDT 
I added checks to the individual commit() methods of the transactional policies to ensure that null is returned when no changes are to be applied by the policy. The code is published on the master branch, therefore, I resolve this ticket as fixed for 3.10.1RC3.
