Setting null in a User Picker with a Behaviours?

[Kay Domschke]

Hi there,
We want to take over fields from an issue picker with the Scriptrunner via Behaviors. That works fine too. Unfortunately we have some issues where user picker fields are empty.
So we have to make a user picker field empty from a behavior if there are no values.

Filling is no problem with setFieldValue(). How can we delete the value again?

We tried the following:
1.) ....setFieldValue("")
2.) ....setFieldValue('')
3.) ....setFieldValue(null)
4.) ....setFieldValue(-1)
5.) ....setFieldValue(0)

Nothing helps

We look forward to every constructive hint / help / solution

setFieldValue(null) is the correct call. I have done some testing on my environment and you are correct - it doesn't work. I would open a ticket with Adaptavist.
