I am not sure if this is the right place to post but maybe someone can help...

I used PhoneGap to package the Map example that comes in the Sencha SDK. The only changes I made was to add and change a few of the javascript and css locations as below:

HTML Code:
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <meta name="viewport" id="viewport" content="initial-scale=1.0,user-scalable=no">
    <script src="javascript/json2.js" type="text/javascript"></script>
    <script src="javascript/phonegap." type="text/javascript"></script>
      <link rel="stylesheet" href="sencha-touch.css" type="text/css">
    <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
    <script type="text/javascript" src="sencha-touch.js"></script>
    <script type="text/javascript" src="plugins/GmapTracker.js"></script>
    <script type="text/javascript" src="plugins/GmapTraffic.js"></script>
    <script type="text/javascript" src="index.js"></script>
    <title>Map Test</title>
When I load it in the BlackBerry simulator all seems ok except after a couple of seconds the google map causes a : JVM Error 104 Uncaught: NullPointerException

Has anyone got any ideas what might cause this??
