jira expression check to customfields with certain values

[Thies Uhlenbruch]

Hey,

for a workflow transition validator I need to build a jira expression which checks:

• customfield_A has the value "Nein" AND customfield_B is not empty

(will be used with script runner)

I never used jira expressions before.

How would I build this expression?

Thanks

Thies

Hi @Thies Uhlenbruch 

Can you try adding Jira Expression 
issue.customfield_A.value == 'Nein' && issue.customfield_B.value.value != null
