    public static LoadingPopup instance = null;
    private LoadingPopup() {

Close the single instance of this dialog...
    public static void close() {
        MessageBox.hide();
    }
    public static LoadingPopup getInstance() {
        if ( == null) {
             = new LoadingPopup();
        }
        return ;
    }

    
Convenience method to popup the message.
    public static void showMessage(final String message) {
    	MessageBox.show(new MessageBoxConfig() {
    		{
    			setTitle(((Constants) GWT.create(Constants.class)).PleaseWaitDotDotDot());
    			setWidth(200);
    			setMsg(message);
    			setClosable(true);
    		}
