Check_MK Werk 7334: Prevent tag groups with a single choice (checkbox) and empty tag ID

ID: 7334 Title: Prevent tag groups with a single choice (checkbox) and empty tag ID Component: WATO Level: 1 Class: Bug fix Version: 1.6.0i1 In previous versions it was possible to create tag groups that had a single choice (shown as checkbox) and an empty tag ID for this single choice. This was not intended and was not usable at all. The tag management GUI and API calls are now preventing this configuration.
