Jspinner with percent formatting

Question

Hi, I want to make a jspinner but with percent formatting. Here is the code:
    private void SetUpSpinner() {
        NumberFormat percentEditFormat;
        NumberFormat percentDisplayFormat;
        percentEditFormat = NumberFormat.getNumberInstance();
        percentDisplayFormat = NumberFormat.getPercentInstance();
        NumberFormatter percentEditFormatter =
                new NumberFormatter(percentEditFormat) {
            public String valueToString(Object o)
                  throws ParseException {
                Number number = (Number)o;
                if (number != null) {
                    double d = number.doubleValue() * 100.0;
                    number = new Double(d);
                return super.valueToString(number);
            public Object stringToValue(String s)
                   throws ParseException {
                Number number = (Number)super.stringToValue(s);
                if (number != null) {
                    double d = number.doubleValue() / 100.0;
                    number = new Double(d);
                return number;
        jformattf = new JFormattedTextField(
                             new DefaultFormatterFactory(
                                new NumberFormatter(percentDisplayFormat),
                                new NumberFormatter(percentDisplayFormat),
                                percentEditFormatter));
        Integer value = new Integer(10);
        Integer min = new Integer(0);
        Integer max = new Integer(100);
        Integer step = new Integer(1);
        SpinnerNumberModel model = new SpinnerNumberModel(value, min, max, step);
        CommisionSp.setEditor(jformattf);
        CommisionSp.setModel(model);
    }If I comment the CommisionSp.setEditor(jformattf); line, the jspinner works fine but without percent format. But if I add that line.... the increase and decrease button does not work at all although I can edit the jspinner directly and when the jspinner lost the focus, my number will be formatted to be percentage formatting.
Any solution???
Thank you.

is this what you're trying to do?
import javax.swing.*;
class Spin extends JFrame
  public Spin()
    super("Spin");
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setSize(200,75);
    setLocation(400,300);
    JSpinner spinner = new JSpinner(new SpinnerNumberModel(0,0,1,.01));
    JSpinner.NumberEditor editor = new JSpinner.NumberEditor(spinner,"0%");
    spinner.setEditor(editor);
    JPanel jp = new JPanel();
    jp.add(spinner);
    getContentPane().add(jp);
  public static void main(String[] args) {new Spin().setVisible(true);}
}
