using latest openhab-addons master branch I now have this error when OH starts:
The XML document '/OH-INF/thing/channels.xml' in module 'org.openhab.binding.openwebnet' could not be parsed: ChannelType 'itemType' must not be null or empty.
the problem is on a Trigger channel type where there is no itemType defined, but this used to be ok until now.
Has something chenged in the parsing of channel-type definitions?
If yes this requires an update to all Trigger channels that have no itemType.
Docs should also be updated (there is no itemType in the example)
