post function upon converting to sub task possible?

[Joachim Schittenhelm]

Hi all, 

I need sub tasks to inherit values from their main issue.

I already solved this with a post function upon creation of sub tasks (via the JMWE). This works perfectly finde.

But when an existing issue is converted to a sub task this does not work. where / how can I enter the post function (or something similar) to inherit the values from the main issue?

I did not find it in the workflow nor by googling it.

thanks for any help

As far as I know, Jira doesn't trigger a transition when converting an issue (the way it does when cloning one). 

Maybe an event listener could help.
