Summary:

A post-function is configured on a transition to create subtask via scriptrunner/JMWE/Automation:

1. Issue is transitioned from Status1 to Status2
2. Subtasks are created (in the background) or field is updated in the background
3. The page should display the created subtask/updated field instantly on the same page.

Expected result:

It would be nice to have post-functions run within the process so that the changes get reflected immediately on the Jira issue without refreshing the page.

Actual Result:

Refreshing the page loads the subtask(s)/field(s) on Jira issue
