When I try to exit a closed ticket I do the following:
click "e" (opens popup)
Make changes I want to make
Click "Update"
Result: after a second the popup is still there, but the data is not saved.
I already changed the workflow and added jira.issue.editable with value "TRUE" (there was no jira.issue.editable available). After this the above was still valid.
Please explain how I can edit a closed ticket.
