Hello, during a transition I would like to be able to test that 2 fields in the issue containing a user name are not identical. I did not find in the possibilities proposed in the conditions, validators or post functions.
I found a possibility to check a constant value for a field but not a comparaison between two fields values of the current issue like it's possible with the IF object in a rule for example.
What I want to do :

Thanks a lot per advance for your help.
