Clicking annotation freezes app

Below is my sample code. The map loads fine, the parameters are passed that are referenced (from another window), and the pin is dropped. However, clicking on it on the device and the simulator causes the app to crash, and the error log doesnt provide anything helpful

var mapview = Titanium.Map.createView({
    mapType: Titanium.Map.STANDARD_TYPE,
    region:{latitude:latitude, longitude:longitude, latitudeDelta:0.5, longitudeDelta:0.5},
    animate:true,
    regionFit:true,
    userLocation:true
});
 
win.add(mapview);
for(x=0;x<1;x++)
 
{       var mySaved = Titanium.Map.createAnnotation({
            latitude:win.lat,
            longitude:win.lon,
            title:win.winTitle,
            subtitle:win.location,
            myid:x,
 
            animate:true,
            rightButton: 'wheel.png',
 
        });
        mapview.addAnnotation(mySaved);
}       
 
 
 
 
mapview.addEventListener('click',function(evt)
{
 
 
    // map event properties
    var annotation = evt.annotation;
    var title = evt.title;
    var clickSource = evt.clicksource;
    var endLat=evt.latitude;
    var endLon=evt.longitude;
 
//alert(evt.annotation.latitude);
    // custom annotation attribute
 
    var myid = (evt.annotation)?evt.annotation.myid:-1;
        if (clickSource=="rightButton")
        {
            var url="http://maps.google.com/maps?saddr=" + latitude +"," + longitude + "&daddr="+endLat+ ","+ endLon;
            //var url="http://maps.google.com/maps?saddr=" + latitude +"," + longitude + "&daddr="+win.location;
        //alert(url);
    Ti.Platform.openURL(url);
        }
 
});

Also, just to note, even if I take out EVERYTHING from the eventlistener and do a simple alert('test'); it freezes and crashes.
