Is there a more eloquent way to achieve this (see title above) as a Cloud customer? Since the parent's 'Updated' field does not get touched when a subtask is touched, I've klujed this which allows me to listen to parents for changes made based on state changes down below on subtasks, and use this trigger to perform other post processing I'm doing with the data outside of JIRA through other integrations I've built.
- Create custom field of type, Date/Time Picker, and call it "Check".
- Add the new "Check" field to all parent issues and subtasks.
- Modify all transitions in all workflows to include (in this order):
- inserting a post function that sets the current date/time (%%CURRENT_DATETIME%%) on the "Check" field on the current subtask.
- inserting a post function that copies the value of "Check" field to the parent's "Check" field.
