Dates in Jtable - tried and tried and tried

Question

I have a table cell renderer to handle the date fields as follows.
The dates appear MM/dd/yyyy when the table is loaded as I want.
SimpleDateFormat cdnDate = new SimpleDateFormat("MM/dd/yyyy");
if (((Vector)fieldInfo.elementAt(i)).elementAt(2).equals ("DATE")) {
      // set format for date display
     column = PassportTable.getColumnModel().getColumn(i);
     // Now get column renderer
     // and set cell renderer for column
     column.setCellRenderer(new DefaultTableCellRenderer() {
          public Component getTableCellRendererComponent(JTable table,
Object value, boolean isSelected, boolean hasFocus, int row, int column) {
               Component renderer = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
                // Create and put formatted date in cell
               setText(cdnDate.format((java.util.Date)value));
               return renderer;
);The problem I have is I cannot get the date that appears as the user edits the field
in this format. I have got yyyy-MM-dd for example the cell shows "01/01/1900"
when the user starts to edit the field "1900-01-01" appears. I have managed
to make a variety of different formats appear but never the one I want.
I have tried the many variations of the following two methods to edit a date in a table cell.
Nothing I have tried has worked.
public void setUpDateEditor(JTable table) {
     //Set up the editor for the date cells.
     try {
          String str = "01/01/1900";
          java.util.Date passDate = cdnDate.parse(str);
          final LimitedDateField dateField = new LimitedDateField(passDate);
          DefaultCellEditor dateEditor = new DefaultCellEditor(dateField) {
               public Object getCellEditorValue() { // return a date
                    //return new java.util.Date(dateField.getValue()); //no compile
                    return dateField.getValue();
          table.setDefaultEditor(java.util.Date.class, dateEditor);
     catch (Exception showUpdatelEx) {}
Where my LimitedDateField class is as follows:public class LimitedDateField extends JTextField implements GlobalInterface {
     private Toolkit toolkit;
     private SimpleDateFormat cdnDate = new SimpleDateFormat("MM/dd/yyyy");
     private char slaSign = '/';
     private int columnLimit;
     private java.util.Date retVal;
     public LimitedDateField(java.util.Date value) {
          //super(columns);
          columnLimit = 11;
          toolkit = Toolkit.getDefaultToolkit();
          setDocument(new DateDocument());
          setValue(value);
     public java.util.Date getValue() {
          String str = "01/01/1900";
          try {
               // retVal = cdnDate.parse(str);
               retVal = cdnDate.parse(getText());
          catch (ParseException e) {Toolkit.getDefaultToolkit().beep();}
          return retVal;
     public void setValue(java.util.Date value) {
          setText(cdnDate.format(value));
     protected class DateDocument extends PlainDocument {
          public void insertString(int offs, String str, AttributeSet a) throws BadLocationException {
               char[] source = str.toCharArray();               
               char[] result = new char[source.length];
               char[] hResult = new char[source.length]; // save
               int j = 0;
               if (super.getLength() > columnLimit - 1){toolkit.beep();}
               else {
                    for (int i = 0; i < result.length; i++) {
                         if (Character.isDigit(source)) {result[j++] = source[i];}
                         else if (source[i] == slaSign) {result[j++] = source[i];}
                         else {toolkit.beep();}
When this failed I tried something simpler - to no avail.
public void setUpDateEditor(JTable table) {
     //Set up the editor for the date cells.
     try {
          SimpleDateFormat cdnDate = new SimpleDateFormat("MM/dd/yyyy");
          DateFormatter df = new DateFormatter(cdnDate);
          JFormattedTextField ftf1 = new JFormattedTextField(df);
     catch (Exception showUpdatelEx) {}Any suggestions????
Thanks
