Problems with Behaviour (Scriptrunner)

[Nikolay]

Hello. Is it possible to make a behaviour, where based on the Jql filter, it will be determined whether there is an entity that occurs once in a custom field of the “issuepicker” type in existing tasks, and then change another field?

I mean logic: there is a situation when you want to creat issue with special custom field issuepicker “A” that has issue “B” inside (you chose it)

than behaviour works like:

“Jql filter” - “finding  previous tasks in project with a custom field issuepicker “A” with one issue “B” inside (every time it can be different issue “B”, but this is can only be chosen once in all tasks)” - “blocking possibility to choose “1” in custom field “C” in the same issue (list type field)”

I know it was difficult to explain, sorry for that

Let me see if I understand...

You are trying to have an issue picker field where the list of issues to pick from is diminished each time a ticket is created that links to one of those issues.

Let's say you have 5 issues that match the JQL to pick from:

AA-1, AA-2, AA-3, AA-4, AA-5

If I create and issue and pick AA-1, the next time I create an issue, AA-1 should not be available in the pick list.

Is that correct?
