“pushModalScreen called by a non-event thread” thrown on event thread

Question

I am trying to get my Blackberry application to display a custom modal dialog, and have the opening thread wait until the user closes the dialog screen.

Seems as though there's a bunch of code in there that's unnecessary.

public class Application extends UiApplication {
    public static void main(String[] args)
    {
        new Application().enterEventDispatcher();
    }

private Application()
{
    final Screen dialog = new FullScreen();
    final ButtonField closeButton = new ButtonField("Close Dialog");
    closeButton.setChangeListener(new FieldChangeListener()
    {
        public void fieldChanged(Field field, int context)
        {
            Application.getUiApplication().popScreen(dialog);
        }
    });
    dialog.add(closeButton); 

    // this call will block the current event thread
    pushModalScreen(dialog);

    System.exit(0);
   }
}
