The code I wrote runs absolutely fine on the browser. But when I connect to wifi on the iPhone I get an error in the debugger :
Javascript Error – Can’t find variable : google

This occurs whenever I call any google maps/directions/geoLocation object.

The code is as follows : 

map = new Ext.Map({
    mapOptions : {
        center : center,
        zoom : 20,
       // mapTypeId : google.maps.MapTypeId.ROADMAP,
        navigationControl: true,
        navigationControlOptions: {
                style: google.maps.NavigationControlStyle.DEFAULT
            }
    },

    listeners : {
        maprender : function(comp, map){
            pos = new google.maps.LatLng(lats, longs, true);
            var marker = new google.maps.Marker({
                 position: pos,
                 //title : 'Sencha HQ',
                 map: map
            });

            map.setMapTypeId(google.maps.MapTypeId.HYBRID);
            setTimeout( function(){map.panTo (pos);} , 1000);
        }
    },

     geo:new Ext.util.GeoLocation({
         autoUpdate:true,
         maximumAge: 0,
         timeout:2000,
         listeners:{
             locationupdate: function(geo) {
                 pos = new google.maps.LatLng(lats, longs, true);
                 center = new google.maps.LatLng(geo.latitude, geo.longitude);
                 if (map.rendered)
                     map.update(center)
                 else
                     map.on('activate', map.onUpdate, map, {single: true, data: pos});
             },
             locationerror: function(geo, bTimeout, bPermissionDenied, bLocationUnavailable, message) {
                 if(bLocationUnavailable){
                     alert('Your Current Location is Unavailable on this device');
                 }
                 else if (bPermissionDenied){
                     alert('Location capabilities have been disabled on this device.');
                 }      
             }
         }
     })
});

The error occurs whenever the code encounters the word google. Also for the LatLng object I get the javascript error : “….result of LatLng not a constructor”

Note : the variables “lats” and “longs” have been defined n given values before this segment of code

    So I had posted this earlier as a comment, but since this is the actual solution to the problem, I’m gonna post it once more 😀

    Ok turns out that the reason I was getting all those errors is cos I was behind a proxy. Weirdly enough the proxy lets me access the google libraries and server when I’m connected using the LAN cable, but not when Im using WiFi. Hope some1 else who’s stuck wid this kind of error will find this somewhat helpful 🙂
