Create JIRA sub-tasks automatically when issue created

Question

I am wondering there is a way to create sub-tasks automatically when issue created.

For example, I create a custom Standard Issue Type, XXX, and Sub-tasks Issue Type YYY

Answer 1

One thing to consider is what happens if the parent issue is closed before all the subtasks are closed. I would recommend putting in a hook to prompt the user to address all the subtasks before closing the issue.
