    useCurrentLocation: true,
}]
         


        

Answer 1

map is not an instance of google map .

var map= Ext.getCmp('mapCanvas').getMap(); // add getMap() here to get the map instance
console.dir(map);
var marker= new google.maps.Marker({
    position: new google.maps.LatLng(25,118),
});
marker.setMap(map);
