1. Create an approval profile (or use an existing one)
2. Go to the edit page
3. Switch it to partitioned type
4. Make some changes on the page, e.g. set admins, or create and fill in notification message.
5. Add or delete a step, partition or field.
The changes in step 4 are then lost. A workaround is to save after step 4 and then go back to the edit page, but it would be nice if the page state could be kept when the page is reloaded when a button is pressed.
