Sub-task Won't inherit Watchers

Question

I have added the post function:

The value(s) of field Watchers will be set from the issue's parent (replacing existing values).

to my sub-task workflow however no matter where I place it - before or after creation - the sub-tasks do not pickup the watchers from the parent ticket.

How can I get this function to pickup?

instead of a post function, create a listener that executes on issue creation.  in your code, look to see if it's a sub-task that's just been created.  if so, then grab the watchers from the parent and add them to your new sub-task.
