Access Priority Field - Jira ScriptRunner Listener

Judah

I am trying to write a listener that will update the "priority" field of all sub-tasks when the parent is updated.

I currently have a listener that works on custom fields...However, since "priority" is not a custom field, my script returns a nullValue error when I try to access the priority field using the method getCustomFieldValue()

Further, the methods getFieldById() - getFieldByName() only work in behaviours. 

The ScriptRunner docs do not provide any valuable information for this specific case...

Regarding listeners:

WHAT METHOD CAN I USE TO ACCESS THE PRIORITY FIELD??

WHAT METHOD CAN I USE TO UPDATE THAT FIELD IN A SUB-TASK?

 

PD Sheehan

The Java API documentation for your version of Jira is your best friend.

When you look up the issue object, you will see that issue.getPriority() will return a Priority object 

def priority = issue.getPriority()
issue.subTaskObjects.each{subTask ->
  subTask.setPriority(priority)
  issueManager.updateIssue(currentUser, subTask, EventDispatchOption.DO_NOT_DISPATCH, false)
  //don't forget to re-index the subtask
}
