Trigger automation when I create a subtask

[Mary Jaekl]

I am attempting to trigger a rule when a subtask is created. Is this not possible?

We are having an issue where components are being left blank when a subtask is created. We'd like to automatically set to match the parent when the subtask is created.

Hi Mary - Welcome to the Atlassian Community!

See the example below with an Issue Created trigger and a Condition for JQL for a subtask Issue type. Then add a new action for Edit Issue and set the value of the Component.

Hi John,

Did you intend to attach an example? I cannot see one.

Here's what I started with - but my problem is that the rule is never triggered when I create a subtask (I do this from the details of a story - selecting More->Create Sub-task). When a story is created it will send the email but obviously doesn't do the rest since it's an issue being created and not the subtask.

Hello Mary,

I might be too late, but for everyone else with the same goal as you and me here is my solution:

It took me a long time to figure this out. I was trying to use the JQL condition, but it never works {{issue.issueType.name}} equals "Sub-task". For some reason, it works when i use Task or Epic instead of Sub-task. I dont know why.
I also tired If or Else. Same thing.
