I added a collumn to our scrum board in OnDemand JIRA Agile but it is not possible to transition from the other columns to this one. The only way I found to add the transition is by copying the workflow and adding the transition to the copy. But I'm reluctant to throw away the workflow and use the copy, since I don't know if JIRA Agile will "approve" such a proceding. When clicking the "simplify workflow" button in board management I get this error message:
There currently exists an active workflow 'Agile Simplified Workflow for Project [...]'. This conflicts with the Agile Simplified Workflow management. Please rename or remove the existing workflow before attempting to convert project [...].
Some time ago I edited the workflow manually in order to trigger notifications on certain transitions. This may be the cause of this problem.
