cordova - _gwt$exception : Cannot read property 'uuid' of undefined -

i working on mgwt-phonegap application.

i using code:

final phonegap phonegap = gwt.create(phonegap.class); phonegap.addhandler(new phonegapavailablehandler() {  @override         public void onphonegapavailable(phonegapavailableevent event) {                //start app - phonegap ready window.alert("phonegap ready");         }});  phonegap.addhandler(new phonegaptimeouthandler() {         @override         public void onphonegaptimeout(phonegaptimeoutevent event) {                 //can not start phonegap - setup  window.alert("can not start phonegap");                }}); phonegap.initializephonegap(); 

when using compiled code target folder, phonegap i.e assets/www folder , running phonegap application. giving me error:

_gwt$exception : cannot read property 'uuid' of undefined 

this script using on index.html page:

<script type="text/javascript" language="javascript" src="cordova.js"></script> <script type="text/javascript" language="javascript" src="myapplication/myapplication.nocache.js"> </script> <script type="text/javascript"> document.addeventlistener("deviceready", (function() {                 cordova.available = true;             }), false); 

this particular code catching exception:

gwt.setuncaughtexceptionhandler(new uncaughtexceptionhandler() {       @override      public void onuncaughtexception(throwable e) {      // todo put in own meaninful handler      window.alert("uncaught: " + e.getmessage());      e.printstacktrace();       }      }); 

just elaborate more:

add device plugin mentioned below. http://docs.phonegap.com/en/3.3.0/cordova_device_device.md.html
