Paint all the JComponents that are in a JPanel

Hi,

I have two classes : AJPanel (extends JPanel) and AJComponent (extends JComponent). The AJPanel constructor adds 10 AJComponent objects to the panel :

 public AJPanel () {
  this.setLayout ( new java.awt.BorderLayout () );
  for ( int i = 0; i < 10; i ++ ) {
   this.add ( new AJComponent () );
  }      

The problem is these components are not drawn on the screen. So I tried overwriting the AJPanel.paintComponent method like this :

 public void paintComponent ( Graphics g ) {
  super.paintComponent ( g );
  for ( int i = 0; i < this.getComponentCount (); i ++ ) {
   this.getComponent ( i ).setLocation ( new Point ( i*5 + 10, i*5 + 10 ) );
   System.out.println ( "theX : " + this.getComponent ( i ).getX () );
   this.getComponent ( i ).update ( g );
  }
 }

And I added some code for debugging purposes to the AJComponent.paintComponent method :

 public void paintComponent ( Graphics g ) {
  System.out.println ( "myX : " + this.getX () );
// ... the rest of the painting code
 }

However, this is what the output is like :

theX : 10
theX : 15
theX : 20
theX : 25
theX : 30
theX : 35
theX : 40
theX : 45
theX : 50
theX : 55
myX : 55
myX : 55

Whereas I was expecting something like :

theX : 10
myX : 10
theX : 15
myX : 15
theX : 20
myX : 20
theX : 25
myX : 25
...
theX : 55
myX : 55


What is going wrong ? How can I paint all the components of the AJPanel ? Currently, only the last one is painted.

Thanks,

Stephane.
