Hi All,

I am using below code

try {
    blackberry.system.event.onHardwareKey(blackberry.system.event.KEY_BACK, handleBack);
    function handleBack() {
        alert("handle back button");
        }
    if (blackberry.ui.menu.getMenuItems().length > 0) {
          blackberry.ui.menu.clearMenuItems();
     }
        var item = new blackberry.ui.menu.MenuItem(false, 1, "Exit", OnClickExitButton);
        blackberry.ui.menu.addMenuItem(item);     
} catch (e) {
    alert('exception (addMenus): ' + e.name + '; ' + e.toString());
}

i am compiling my application in WW sdk2.3. and running application on deivce. It gives "Refrence Error: handleBack is not defined".

Please help me to find out reason. I am stuck here. Not able to add menuitem in application.

Your problem is only that you're defining the function _after_ you're using it. Change to this:

    var handleBack = function () {
        alert("handle back button");
        }

    blackberry.system.event.onHardwareKey(blackberry.system.event.KEY_BACK, handleBack);

or even better:

    blackberry.system.event.onHardwareKey(blackberry.system.event.KEY_BACK, function() { alert('handle back'); });
