how do I use the Issue Assignment Listener to automatically set the assignee of all sub-tasks to match the parent?

[Jeannette Lamb]

We are using JIRA 6.0.8. I do not want to base this on a workflow transition because the assignee could be updated on a parent issue at any time without changing the workflow state.

Also, can this be done for only selected projects or will it affect all projects in JIRA?

Thank you,

Jeannette

You can try this:
