Description of problem:
When two users open the same process, make changes and save them, changes that were saved earlier by one user will be "silently" overwritten by the other user.

Version-Release number of selected component (if applicable):
6.1.4.CR1

How reproducible:
-

Steps to Reproduce:
See bz 1184487.

Actual results:
The user who attempts to save his work after someone else has already committed a change does not see the conflict dialog and so is not given the choice to either force-save or reopen the process.

Expected results:
Conflict dialog should be displayed to the user if someone else has already committed a change.
