I am creating landmarks on demand in c++, and using LandmarkModel in qml. The ProximityFilter works in the qt simulator but on the device it works some time but not others for no obvious reason. The CategoryFilter doesn't work at all.
So I think I have to revert to creating a custom geomap qml c=+ plugin...
And a custom dbus SMS send work around.
Enough to drive me to java ;-)
