Please change to "Event". Datum: is a message that comes regularly in a certain period. Event: is a message that comes on a request only and can happen anytime. Please update the SDDUI 286.
This is used in INTERPRET_RECVD_MT_MESSAGE in MessageInterpreter.cpp. It is overridden so a broadcast is sent out instead of a direct message to the HD.
As it seems in the qml these properties are not used directly in UI and only the key/value pairs are used. So it would be better to have key or value as QStringList properties and change these properties to just values.
