I want to create an add-on (plug-in) but I want to use existing custom fields in my JIRA. Is there a chance I can do that?
It's not only the value of the field that I want to get, but the field itself, e.g. a normal User Picker field that will search for users while I'm typing username.
I could find this example, but you have to explicitly click on the button and get another screen, otherwise it behaves like a usual text field.
