Fields display "Not Available" in transition screen
When the user starts the said transition, the screen correctly displays the values in those fields.
When the user is done entering the other required fields for the transition and clicks the button to complete the transition, the transition fails and the screen comes back indicating that the previously populated fields are required (and missing) and those fields now display the pre-populated value but this time they have "(Not Available)"
By the way those 2 fields are required through transition validation. I've tried both Fields Required (JSU) and Fields Required Validator (JMWE add-on) and both result in the same situation. It looks to me like there is some sort of timeout for validations and that seems to expire before it is able to confirm the 2 fields already have values.
Umm, I just checked the release notes for scriptrunner for jira 6.18 and they mention a bug fix SRJIRA-4723 - Read-only values are no longer lost when configuring Edit screen fields for user pickers. The fields where my issue occurs are all read-only fields set as such via scriptrunner behaviours. The other issue we have been facing is that some times when users would go to the Edit screen, some of the fields that are read-only get blanked out. However that happens with all kind of picker fields not only user fields. It also happens with the Summary field.
We will upgrade scriptrunner from 6.17 to 6.19 and see if this persists
