appendchild, error?

[Peppe <pe...@gmail.com>]

Hi, i have inserted a rect in my svgCanvas where, before, i load a file svg.
when i want to move an element i can move elements contained in loaded svg
file, instead the rect that i inserted no...why?

For my application i use a Japplet:

public class tesi extends JApplet {

        final JPanel panel = new JPanel(new BorderLayout());
	final String svgNS = "http://www.w3.org/2000/svg";  //  @jve:decl-index=0:
	public JPanel jContentPane = null;
	public JButton jButton = null;
        JSVGCanvas svgCanvas = new JSVGCanvas();

       private JToggleButton muovi = null;
	private JButton Circle = null;


       String SCALE = "scale";
       String DRAG = "drag";
       String action;
       EventTarget actionNode, actionTgt;
       SVGPoint startPt;
       boolean dragged = false;
  
        public tesi() {
		super();
	}

       public void init() {
		this.setSize(600, 400);
		this.setContentPane(getJContentPane());
	}


       public JPanel getJContentPane() {
		if (jContentPane == null) {
			label.setBounds(new Rectangle(78, 4, 137, 31));
			jContentPane = new JPanel();
			jContentPane.setLayout(null);
			jContentPane.add(getJButton(), null);
			jContentPane.add(getJSVGCanvas(), null);
			jContentPane.add(label, null);
			jContentPane.add(getZoomIN(), null);
			jContentPane.add(getZoomOUT(), null);
			jContentPane.add(getProva(), null);
			jContentPane.add(getMuovi(), null);
			jContentPane.add(getCircle(), null);
		}	
              return jContentPane;
	}

       //in this method i load the svg file
        public JButton getJButton() {
		
		if (jButton == null) {
			jButton = new JButton();
			jButton.setBounds(new Rectangle(10, 5, 59, 28));
			jButton.setText("load");
			jButton.addActionListener(new ActionListener() {
	            public void actionPerformed(ActionEvent ae) {
	                JFileChooser fc = new JFileChooser(".");
	                int choice = fc.showOpenDialog(panel);
	                if (choice == JFileChooser.APPROVE_OPTION) {
	                    File f = fc.getSelectedFile();
	                    try{
	                    	svgCanvas.setURI(f.toURL().toString());  //carica
l'immagine dal file all'interno del canvas   
	                    }catch(IOException error){
	                    	error.printStackTrace();
	                    }

	                }
	                }
	            });
		}
		return jButton;
	}


       //this method initializes JSVGCanvas

       public JSVGCanvas getJSVGCanvas() {
			svgCanvas.setBounds(new Rectangle(114, 54, 476, 333));
			svgCanvas.getInteractors().add(rotateInteractor);

			svgCanvas.setDocumentState(JSVGComponent.ALWAYS_DYNAMIC);
		return svgCanvas;
	}

       private JButton getCircle() {
	if (Circle == null) {
		Circle = new JButton();
		Circle.setBounds(new Rectangle(5, 173, 92, 32));
		Circle.setText("circle");
		Circle.addActionListener(new java.awt.event.ActionListener() {
			public void actionPerformed(java.awt.event.ActionEvent e) {
				svgCanvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new
Runnable() {
					public void run() {
							SVGDocument doc = svgCanvas.getSVGDocument();
                			//svgCanvas.setDocument(doc);
