Is it possible to set a field value when a user clicks a transition, so that the new value appears in the transition screen?

Hello @Phil Bustin 

You can't create an Automation Rule that will execute when a status transition is selected but has not yet been completed. The Issue Transitioned trigger is triggered after the transition is completed.

You can't use Automation Rules to set values on Screens that are being used by Transitions.

There is a change request in Atlassian's backlog to build in support for setting default values in a Transition screen when the transition is selected.

https://jira.atlassian.com/browse/JRACLOUD-13604

It might be possible to do this with a third party app, like Adaptavist Scriptrunner, but I have not actually explored this use case in Jira Cloud.

As a workaround, I set up transition pairs, so that the first transition has no screen, but triggers an automation that runs a second transition containing the screen.  It didn't work: apparently, a triggered transition won't show its screen.

Correct. Automation rules don't allow for any user interaction in the midst of the rule execution.
