Inside the QML Map class there is a MapItemView item. This item uses a delegate that receive a "model" property from the MapLocationModel, but infact that's a QObject with the MapLocation defined properties. That's how MapItemView works. The problem here is that "model" QObject cannot be cast back to a MapLocation as the meta data in there does not include a MapLocation sub-class, for some reason. Even if using propery() on that QObject to fetch data like coordinates works, instead of storing this strange object pointer, store the MapLocation UUID (from dive_site) which is a uint32_t. setSelectedUuid() deals with this oddity and finds the correct MapLocation pointer in the table and dispatches a selectedLocationChanged() signal for it.
