On Sitecore v8.2
If workflow is used, items need to be locked to be edited and explicitly unlocked by the content author when they are done.
To automatically unlock the items upon save, we can change AutomaticUnlockOnSaved setting value to true. However, that doesn't work on item that doesn't contain any fields eg: Carousel parent folder that would contain carousel items. Carousel parent folder needs to go through the workflow, but since it doesn't have any fields, the item is not unlocked automatically upon item save.
Anyone knows of a way around this?
