Validate Multi Select User Custom Field value against User CF value

Question

Hello,

I am stuck with something which seems to be very easy but somehow I cannot figure it out.

We want to have a Workflow validator during a transition that will check the following:
Single Select Custom Field (User Pickup) called Code Reviewer value does not exist in 
Developer(s) - Multi Select Custom Field (User Pickup). 
Example, if we have: 
Code Reviewer = John Smith
Developer(s)  = John Smith (may include more users eg. Peter Goosters, Dave Jones) 
The transition should throw an error.

I am using Script Validator [ScriptRunner]  - Simple scripted validator and I tried the following without success:

cfValues['Developer/s'] != cfValues['Code Reviewer']

!(cfValues['Developer/s']*.value.contains(cfValues['Code Reviewer']?.value))

(cfValues['Developer/s'] as int) >= (cfvalues['Code Reviewer'] as int)

cfValues['Developer/s']*.value != cfValues['Code Reviewer']?.value

Any help Is highly appreciated. I guess I will need to write more complex code to extract the multiselect values and compare them with my single select fields but I don't know how. And also I don't know if because these are user field it's even more complicated :)

Thanks in advance

Unfortunately the transition is not allowed with this code :(

cool, this is pretty easy, place below snippet in conditions instead of validator

cfValues['Code Reviewer']*.value not in cfValues['Developer/s']*.value

if the condition fails, you'll see that particular transition hidden until the condition becomes true

BR,

Sorry, I was not clear enough. I want to allow the transition only if the value of Code Reviewer is not found in the Developer/s multi-select field.
