I've created a Sencha Touch App and I am using this with Phonegap to generate a Blackberry App.

I want to make use of the hardware back button, which is possible via BB Webworks and works, but only as long as I don't add Sencha Touch. It works fine when not using Sencha Touch, but the event seems not to be caught when Sencha Touch js-files are added.



Code:
       <script type="text/javascript">    
         blackberry.system.event.onHardwareKey(blackberry.system.event.KEY_BACK, 
            function() { 
                alert("back");
                //history.back();
                return true;
            }); 
    </script>
Any clues why?

Thanks!
