Problem with Invisible Caret in JTextPane

Question

Hi there,
Using latest JDK, I'm running into the following problem - a JTextPane, placed in a JScrollPane, made editable by doubleclicking on it, doesn't show the caret after having been made editable.
private class EditableTextPane extends JTextPane{
          private String preEditString;          
          protected EditableTextPane(){
               super();
               setFont( TicketPanel.ticketFont );
               setMargin( new Insets( 24, 5, 5, 5 ) );
               setEditable( false );
               addMouseListener( new MouseAdapter(){
                    public void mouseClicked( MouseEvent e ){
                         if( e.getClickCount() == 2 ){
                              if( !isEditable() ){
                                   preEditString = getText();
                                   setEditable( true );
//added these two in an attempt to solve the problem
                                   EditableTextPane.this.requestFocus();
                                   EditableTextPane.this.setCaretPosition( getText().length() );
                              else{
                                   performEdit();
                                   setEditable( false );
          public void setText( String s ){
               super.setText( s );
               if( isEditable() )
                    setEditable( false );
               preEditString = null;
          private void performEdit(){
               if( preEditString == null )
                    return;
          public void setEditable( boolean b ){
               super.setEditable( b );
               setForeground( b ? Color.blue : Color.black );
     }Any ideas?
Thanks!

Thanks for the post camickr, didn't think of that, but unfortunately that didn't do it. Here's the SSCE:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TestClass {
     public static void main( String args[] ){
          JFrame f = new JFrame();
          EditableTextPane e = new EditableTextPane();
          e.setText( "This is some test text" );
          JScrollPane p = new JScrollPane( e, ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS );
          f.getContentPane().add( p );
          f.setSize( 400, 400 );
          f.setVisible( true );
     private static class EditableTextPane extends JTextPane{
          private static final long serialVersionUID = 1L;
          private String preEditString;          
          protected EditableTextPane(){
               super();
               setMargin( new Insets( 24, 5, 5, 5 ) );
               setEditable( false );
               addMouseListener( new MouseAdapter(){
                    public void mouseClicked( MouseEvent e ){
                         if( e.getClickCount() == 2 ){
                              if( !isEditable() ){
                                   preEditString = getText();
                                   setEditable( true );                              
                                   EditableTextPane.this.requestFocus();
                                   SwingUtilities.invokeLater( new Runnable(){
                                        public void run(){
                                             EditableTextPane.this.setCaretPosition( getText().length() );
                              else{
                                   performEdit();
                                   setEditable( false );
          public void setText( String s ){
               super.setText( s );
               if( isEditable() )
                    setEditable( false );
               preEditString = null;
          private void performEdit(){
               if( preEditString == null )
                    return;
          public void setEditable( boolean b ){
               super.setEditable( b );
               setForeground( b ? Color.blue : Color.black );
}Thanks again.
