Can we have sub-task assignee automatically copied to parent story if parent is unassigned?

[nghoffman]

We create a story with multiple subtasks.  I assign a subtask to myself.  We would like this to automatically copy the subtask assignee to the parent story, if the parent story is current unassigned.  So, the first person assigned to a subtask would also get assigned to the currently-unassigned parent story.

Hello,

You would need an app for it. There are multiple apps available: Power Scripts, ScriptsRunner, Automation for Jira.

If you choose the Power Scripts app, then you could write a listener for the Issue Assigned event with a code like this:

if (issueType == "Subtask" and isNull(parent.assignee)) {

  parent.assignee = assignee;

}
