I have a custom field called "Request Description" that has some simple wiki markup within it as a default value.
As a post function when creating the issue, the contents of "Request Description" are copied to the Description field. This is then shown and used everywhere instead of the Request Description field.
It is my way of having a default value for Description for a specific project.
This works fine, however what I need is when an issue from another project (it also has the Request Description field) is moved to this project, I need the Request Description copied to Description.
I thought moving the issue may trigger the create issue transition, however it doesn't.
Anybody have any thoughts how I can get the value copied when an issue is moved?
