When I try to make 2 views of the same document in 2 JTextPanes
in a JSPlitPane and the document contains a component, it does
not function properly and generates and ArrayIndexOutOfBounds
Exception: No such child: 0. You need to resize the window to
see partial function.



SOURCE EXAMPLE:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class TextPaneTest extends JSplitPane {


     public TextPaneTest ( ) {
          
          super( JSplitPane.VERTICAL_SPLIT );

          JTextPane top = new JTextPane( );
          top.insertComponent( new JButton( "Test" ));
      
          JTextPane bottom = new JTextPane( );
          bottom.setDocument( top.getDocument( ) );

          setTopComponent( new JScrollPane( top,
               JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
               JScrollPane.HORIZONTAL_SCROLLBAR_NEVER ) );
          
          setBottomComponent( new JScrollPane( bottom,
               JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
               JScrollPane.HORIZONTAL_SCROLLBAR_NEVER ) );
     }
    
    public static void main ( String [ ] args ) {
       
         JFrame f = new JFrame( );
         Container c = f.getContentPane( );
          
          c.add( new TextPaneTest( ) );
          
         f.addWindowListener( new WindowAdapter ( ) {
              public void windowClosing( WindowEvent evt ) {
                 System.exit( 0 );
              }
         } );

           f.pack( );
           f.setVisible( true );
           f.setSize( 750, 400 );
      }

}
