How can I get this simple scripted validator to work?

[Matthew Mallard]

G'evening,

I have a simple scripted validator set on one of the transitions in my Story workflow. The goal is to prevent the transition if the Story has the "Type" custom field set to "Software" and the "Test Criteria" custom field is blank. Here's what I got which isn't working.

(cfValues['Type'] != 'Software') || (cfValues['Type'] == 'Software' && cfValues['Test Criteria'])

Hello Manuel! Did you find the answer? Is it possible to know whether the permission has been added or removed?

Hello Ekaterina, 

sorry, found no solution back then. To be honest I didn't look further into it. So there might be a solution now, that I don't know of.
