I just realised today that all my items of type color seem to be broken in some way. Could this be related to the upgrade to 3.1? It was working in M5 before.
What happens is the the items are not null but in a somewhat undefined state. They don’t get rendered correctly in the UI (see screenshot) and the items are not shown in the list when I want to link a thing channel to them.
Needless to say that rules that try to interact with these items fail but I have not seen a useful error message so far. I just says: failed to execute action.
This problem also occurs for newly created color items. I already cleared the cache and deleted persistence without any effect.
Any ideas anyone?
