Some dialogs where i have to input text freeze

Question

the problem is only in some compilers.
i attach a copy of my code
package rail.editor;
import rail.model.*;
import javax.swing.JOptionPane;
import javax.swing.*;
import java.beans.*; //Property change stuff
import java.awt.*;
import java.awt.event.*;
public class RenameStationDialog extends JDialog {
private String typedText = null;
private JOptionPane optionPane;
private Network network = null;
private Station station = null;
public String getValidatedText() {
return typedText;
public RenameStationDialog(JFrame frame, final Station st,
               final Network network) {
super(frame, "Rename Station ",true);
     this.network = network;
     station = st;
final String msgString1 = "Enter the new station name";
final JTextField textField = new JTextField(station.getName(), 10);
     textField.selectAll();
Object[] array = {msgString1, textField};
final String btnString1 = "Enter";
final String btnString2 = "Cancel";
Object[] options = {btnString1, btnString2};
optionPane = new JOptionPane(array, JOptionPane.PLAIN_MESSAGE,
                    JOptionPane.YES_NO_OPTION,
                    null,
                    options,
                    options[0]);
setContentPane(optionPane);
setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
optionPane.setValue(new Integer(
JOptionPane.CLOSED_OPTION));
textField.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
optionPane.setValue(btnString1);
     // rename dialog properties
     setResizable(false);
     setLocationRelativeTo(getOwner());
     pack();
optionPane.addPropertyChangeListener(new PropertyChangeListener() {
public void propertyChange(PropertyChangeEvent e) {
String prop = e.getPropertyName();
if (isVisible()
          && (e.getSource() == optionPane)
          && (prop.equals(JOptionPane.VALUE_PROPERTY) ||
               prop.equals(JOptionPane.INPUT_VALUE_PROPERTY))) {
Object value = optionPane.getValue();
if (value == JOptionPane.UNINITIALIZED_VALUE) {
//ignore reset
return;
optionPane.setValue(JOptionPane.UNINITIALIZED_VALUE);
if (value.equals(btnString1)) { // user presses ok
               typedText = textField.getText();
               try {
               network.rename(station, typedText);
               } catch (ModelException me) {
               String error = me.getMessage();
               JOptionPane.showMessageDialog(
RenameStationDialog.this,
"Sorry, cannot rename station\n"
+ error,
                         "Renaming Error",
JOptionPane.ERROR_MESSAGE);
               typedText = null;
               setVisible(false);
          } else { // user closed dialog or clicked cancel
               typedText = null;
               setVisible(false);
     }); // end of property change listener
I call the dialog like that:
          RenameStationDialog d = new RenameStationDialog(editor,
                              selectedStation, network);
          // show the dialog for renaming
          d.setVisible(true);

I have the same problem (and struggle with it!). A JOptionPane.showInputDialog that works with jdk1.3 suddenly freezes my application when run with 1.4. Funny thing is, other calls to JOptionPane.showInputDialog work perfectly fine... Hm...
I haven't found any solution for it, though. I tried compiling with jdk1.3 and then running with jdk1.4, but the problem persists. But as I said, running it with jdk1.3 does not cause the application to hang.
Sorry to be of no help. Hope someone else knows a workaround!
