Graphics / Image-Handling problem

Question

I am trying to draw an image of one JPanel onto another JPanel, using the code below.
Instead of a picture of the source JPanel, i get only a white rectangle on the target JPanel.
I would greatly appreciate any help on fixing my code.
A JPanel, "sourcePanel" exists.
GraphicsConfiguration gfxConfig =
     GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getDefaultConfiguration();
BufferedImage sourcePanelImage =
     gfxConfig.createCompatibleImage(sourcePanel.getWidth(),
                                             sourcePanel.getHeight());
Graphics2D sourceGraphics =
     (Graphics2D) sourcePanelImage.getGraphics();
     sourcePanel.paint (sourceGraphics);
TargetPanel targetPanel = new TargetPanel( sourcePanelImage.getWidth(), sourcePanelImage.getHeight(), sourcePanelImage );
PopFrame popFrame2 = new PopFrame( targetPanel, sourcePanelImage.getWidth(), sourcePanelImage.getHeight() );
import java.awt.*;
import javax.swing.*;
import java.awt.image.BufferedImage;
class TargetPanel extends JPanel {
     int width;
     int height;
     BufferedImage image;
     public TargetPanel( int width, int height, BufferedImage image ) {
          this.width = width;
          this.height = height;
          this.image = image;
          setLayout( new BoxLayout( this, BoxLayout.Y_AXIS ) );
          setPreferredSize( new Dimension( width, height ) );
          setMinimumSize( new Dimension( width, height ) );
          setMaximumSize( new Dimension( width, height ) );
          setBackground( Color.orange );
     public void paintComponent(Graphics g) {
          super.paintComponent(g);                                        //     Paint background, borders
          g.drawImage( image, 0, 0, width, height, this );
     ...          Println's show that the image exists:
"sourcePanelImage.getWidth() = 170
sourcePanelImage.getHeight() = 180
sourcePanelImage = BufferedImage@b4ee5e: type = 3 DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=ff000000 IntegerInterleavedRaster: width = 170 height = 180 #Bands = 4 xOff = 0 yOff = 0 dataOffset[0] 0
but the result is only a white rectangle on "targetPanel"
Many thanks in advance for a solution.
