Before 1.3 beta, fireTableDataChanged() kept the selected lines.
Now, the behavior is different, the whole selection is lost.

------------

9/29/99 eval1127@eng -- setNumRows() deprecated, so tried tablemodel.removeRow(), followed by fireTableDataChanged...sure enough, selection lost.
Previous bugs seemed to deal with this, but can't find one that's still open.

Using variant of test case from bug # 4267264:

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

public class TestTable {

        public static void main( String[] argv ) {
                JFrame frame = new JFrame( "List TestTable" );
                frame.addWindowListener( new WindowAdapter(){
                  public void windowClosing( WindowEvent e ){
                    System.exit( 0 );}});

                final DefaultTableModel model = new DefaultTableModel( 0, 2 );
                model.addRow (new Object[] {"R1", "r1"});
                model.addRow (new Object[] {"R2", "r2"});
                model.addRow (new Object[] {"R3", "r3"});

                final JTable table = new JTable( model );

                JButton button = new JButton( "get selection Indexes" );
                JButton button0 = new JButton( "setNumRows( 0 )" );
                JButton button1 = new JButton( "setNumRows( 1 )" );
                button.addActionListener( new ActionListener() {
                    public void actionPerformed( ActionEvent e ) {
                        System.out.println ("anchorRow = " 
                        + table.getSelectionModel().getAnchorSelectionIndex());
                        System.out.println ("anchorCol = " 
                        + table.getColumnModel().getSelectionModel().getAnchorSelectionIndex());
                    }
                });
                button0.addActionListener( new ActionListener() {
                    public void actionPerformed( ActionEvent e ) {
                        model.setNumRows( 0 );
                    }
                });

                button1.addActionListener( new ActionListener() {
                    public void actionPerformed( ActionEvent e ) {
                        // model.setNumRows( 1 );
                                                model.removeRow(2);
                                                model.removeRow(1);
                                                // model.fireTableDataChanged();	// this makes selection get lost
                    }
                });

                frame.getContentPane().setLayout( new GridLayout( 4, 1 ) );
                frame.getContentPane().add( table );
                frame.getContentPane().add( button );
                frame.getContentPane().add( button0 );
                frame.getContentPane().add( button1 );

                frame.pack();
                frame.show();
        }
}
