Paint Event does not fire until teh frame has been resized

Hi all

I have a problem with a small app I am creating.
I have attached some of the Class code below.

When the app starts the objects are not visible in the frame.
To make the objects visible I have to manually resize the
window then all objects become visible.

I have placed an println statement in the Paint function and there
is no output until I resize which indicates that the Paint function
is not firing the first time.

It does then function correctly all the time and the window is
repainted every time an object is moved.

Does Anybody have any idea what I am doing wrong ?

Many thanks

  private TheController controller;
  private JFrame frm;

  private static int F_HEIGHT = 400;

    pnl.add(this);

    frm.setAlwaysOnTop(true);

    addKeyListener(this);

    ((Observable) model).addObserver(this);
    }

  // Paint the game on the screen using the state (the model)
  public void paint(Graphics g)
    {
    // There is a problem as this Paint function is not being fired at
the start
    System.out.println("Painting");

    Graphics2D g2 = (Graphics2D)g;

    g2.setColor(new Color(255, 0, 0));
