reverseGeolocation - parts of address undefined

Using code like herunder (where p is the location returned from getCurrentPosition), street and houseNumber remain undefined, while city and country are returned correctly. Anyone?

var SEARCH = new ovi.mapsapi.search.Manager();
SEARCH.addObserver("state", function(observedManager, key, value){
if (value == "finished") {
if (observedManager.locations.length > 0) {
if (observedManager.locations[0].address.street) {
document.getElementById("lblStreet").innerHTML = observedManager.locations[0].address.street;
}
if (observedManager.locations[0].address.city) {
document.getElementById("lblCity").innerHTML = observedManager.locations[0].address.city;
}
if (observedManager.locations[0].address.houseNumber) {
document.getElementById("lblHouseNumber").innerHTML = observedManager.locations[0].address.houseNumber;
}
if (observedManager.locations[0].address.country) {
document.getElementById("lblCountry").innerHTML = observedManager.locations[0].address.country;
}
}
}
else
if (value == "failed")
alert("The automatically triggered search request in the Search example failed.");
});
alert(p.coords.latitude);
alert(p.coords.longitude);
var loc = new ovi.mapsapi.geo.Coordinate(p.coords.latitude, p.coords.longitude);

SEARCH.reverseGeocode(loc);
SEARCH.clear();
