Why does AbstractCellEditor changes line at VK_ENTER, DefaultCellEditor not

Question

Hi,
For BigDecimal values I wrote my own CellEditor which extends AbstractCellEditor.
However compared to the DefaultCellEditor there is a servere difference/problem:
When hitting <ENTER> in edit-mode, the AbstractCellEditor changes the line of the selection (y+1), whereas DefaultCellEditor simply jumps to the next cell right of it (x+1).
This is really irritating, because my users tend to work mostly keyboard-only.
Any idea how to get the DefaultCellEditor behaviour with my own Editor too?
Thank you in advance, Clemens

Well it doesn't work if you start editing with the mouse (because the editor has focus and not the table I think) and I don't see anything special in DefaultCellEditor (just a call to stopCellEditing() in actionPerformed()).
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TestTable4 {
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    // both with Metal + Windows L&F for me
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                catch (Exception e) {
                    e.printStackTrace();
                JTable table = new JTable(5, 5);
                //            table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(
                //                    KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "selectNextColumnCell");
                JFrame frame = new JFrame("Test");
                frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                frame.getContentPane().add(new JScrollPane(table));
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
}
