BlackBerry Menu Item

What is the correct way in order to push an screen when the user press a Menu Item? I'm developing my code in this way but i don't know if it is the right:

    private MenuItem _descriptionItem = new MenuItem("Descripción",110, 10) {
    public void run() {
        int selectedIndex = _listField.getSelectedIndex();
        final Event event = (Event)_listElements.elementAt(selectedIndex);
        UiApplication.getUiApplication().invokeLater(new Runnable(){
            public void run(){
                Dialog.inform(event.getDescription());
            }
        });
    }
};

Thanks!

This is actually deprecated:

private MenuItem _descriptionItem = new MenuItem("Descripción",110, 10) 
{
    public void run() {
        int selectedIndex = _listField.getSelectedIndex();
        final Event event = (Event)_listElements.elementAt(selectedIndex);
        Dialog.inform(event.getDescription());
    }
};

Use this instead:

private MenuItem _descriptionItem = new MenuItem(new StringProvider("Descripción"),110, 10)
{
    public void run() {
        int selectedIndex = _listField.getSelectedIndex();
        final Event event = (Event)_listElements.elementAt(selectedIndex);
        Dialog.inform(event.getDescription());
    }
};

This will avoid compiler warnings when using Menu Item.

private MenuItem MNU_BACK = new MenuItem(null, 100000000, 100) { public void run() { closeform(); }

         public String toString() {
                 return "BACK";
     }
  };

menu items are executed on the event thread. So you can remove invokeLater code.

 private MenuItem _descriptionItem = new MenuItem("Descripción",110, 10) {
    public void run() {
        int selectedIndex = _listField.getSelectedIndex();
        final Event event = (Event)_listElements.elementAt(selectedIndex);
        Dialog.inform(event.getDescription());
    }
};
