Description of problem:
When 2 users work on the same process, one saves and the other tries to save after that as well, he will get the conflict Error pop-up with 'User admin has updated the following resource..' and options to Force save, Reopen or Cancel.

If the user tries to Reopen, the Designer will be closed, the process will be saved instead (can be verified if you Cancel the error pop-up and reopen the process) and the error pop-up will stay present and operational.

The process/Designer definitely won't be, in any way, reopened.

The same behaviour can be reproduced with only one user and two saves without reopening in between the saves.

Version-Release number of selected component (if applicable):
BPMS 6.0 ER7

Steps to Reproduce:
1. User u1 and u2 both open the same process in Designer.
2. User u1 makes a change and saves.
3. User u2 makes a change and saves.
4. In the error pop-up, u2 chooses Reopen.

Actual results:
Designer is closed, the process is saved and the error pop-up stays present and operational.

Expected results:
Process is not saved, Designer reloads with the process in the version from first save, pop-up disappears.
