I have a JTable, whose data model is a DefaultTableModel I've subclassed.

I've overridden removeRow() to call super.removeRow() and then fireTableDataChanged().

Before I add rows to the table, the selectedRow=-1 as expected.
I first add a few rows to the table, then I delete
the currently selected row. After I delete the last row (now rowCount=0),
I look at the selectedRow; it returns 0 instead of -1,
even though there no longer is a row 0.

This is a sample that I wrote to demonstrate the problem.

import com.sun.java.swing.*;

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

        DefaultTableModel model = new DefaultTableModel( new Object[] { "One", "Two" }, 0 ) {
            public void removeRow( int row ) {
                super.removeRow( row );
                fireTableDataChanged();
            }
        };

        JTable table = new JTable( model );
        System.out.println( "starting selected row: " + table.getSelectedRow() );

        model.addRow( new Object[] { "smatter", "chew" } );
        model.addRow( new Object[] { "momynyms", "wentothustore" } );
        model.addRow( new Object[] { "mungry", "squeet" } );

        System.out.println( "selected row after adding items: " + table.getSelectedRow() );

        table.setRowSelectionInterval( 1, 1 );

        System.out.println( "selected row after setting selection: " + table.getSelectedRow() );

        model.removeRow( 1 );
        model.removeRow( 0 );
        model.removeRow( 0 );

        System.out.println( "selected row after deletions: " + table.getSelectedRow() );

        frame.getContentPane().add( table );

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