@morph166955 My test setup for Basic UI (see NPE in ItemDTOMapper, produced in PageChangeListener · Issue #897 · openhab/openhab-core · GitHub) now (build OH 2.5.S1634) is working without any error message. Do you think it could be an issue with the App? AFAIK there was a recent change of the handling for invisible widgets (see Add proper handling for invisible widgets. by maniac103 · Pull Request #1174 · openhab/openhab-android · GitHub).
