How can I restrict users from editing an issue while allowing them to manage a custom user field in the People section of an issue?
Background:
My project is locked down. Only certain groups can see and edit all the tickets in it.
Anyone can create tickets and view them. But after a certain point in the workflow, these users with view access can no longer edit them.
I have a custom user picker field that gives view access to the people selected. I want them to be able to add or remove themselves from that field, but don't know how to lock the entire ticket while giving them edit privileges on the one field.
Thank you!
