Keybinding in JDialog

Hi, I want to ask about keybinding.
Keybinding in f1 (jframe) works fine but somehow keybinding in d1 (jdialog) does not work.
Here is my code below. Can someone tell me what mistake I've made?

Code:

import java.awt.BorderLayout; import java.awt.event.ActionEvent; import javax.swing.AbstractAction; import javax.swing.JDialog; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.JTextField; import javax.swing.KeyStroke; import javax.swing.table.DefaultTableModel; public class Dialog2 { private static JFrame f1; public static void main(String[] args) { f1=new JFrame("Frame"); f1.setBounds(100, 100, 450, 300); f1.setLocationRelativeTo(null); f1.getContentPane().setLayout(new BorderLayout()); f1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel f1cp=new JPanel(); f1.getContentPane().add(f1cp, BorderLayout.CENTER); f1cp.setLayout(null); String[] columnNames = {"CODE", "NAME"}; Object[][] data = {{null,null}}; DefaultTableModel model = new DefaultTableModel(data, columnNames); JTable f1table=new JTable(model); JScrollPane f1sp=new JScrollPane(f1table); f1sp.setBounds(20, 20, 400, 230); f1cp.add(f1sp); f1.setVisible(true); f1table.getInputMap().put(KeyStroke.getKeyStroke("pressed ENTER"), "f1enter"); f1table.getActionMap().put("f1enter", new AbstractAction(){ @Override public void actionPerformed(ActionEvent e){ showd1(); } }); } //end of main(string... private static void showd1(){ JDialog d1=new JDialog(f1, "Dialog", true); d1.setBounds(20, 20, 410, 280); d1.setLocationRelativeTo(f1); JPanel d1cp=new JPanel(); d1.getContentPane().add(d1cp, BorderLayout.CENTER); d1cp.setLayout(null); JTextField d1tf= new JTextField(); d1tf.setBounds(20, 20, 360, 30); d1cp.add(d1tf); String[] columnNames = {"CODE", "NAME"}; Object[][] data = {{null,null}}; DefaultTableModel model = new DefaultTableModel(data, columnNames); JTable d1table=new JTable(model); JScrollPane d1sp=new JScrollPane(d1table); d1sp.setBounds(20, 70, 360, 170); d1cp.add(d1sp); d1.setVisible(true); d1tf.getInputMap().put(KeyStroke.getKeyStroke("pressed ENTER"), "d1tfenter"); d1tf.getActionMap().put("d1tfenter", new AbstractAction(){ @Override public void actionPerformed(ActionEvent e){ d1table.setValueAt(1,0, 0); } }); } }

Thank you.
