PasswordTextField not showing the value

[Josh Kamau]

 I have would like to edit an existing user's properties including the
password. However, all the other properties are appearing on their
corresponding fields except the password field. How do i make it appear?.

   here is my component for editing users


   public class UserPanel extends Panel {

    /**
     *
     */
    private static final long serialVersionUID = 3819937222116190372L;

    @Inject
    private UserDao userDao;

    private TextField<String> txtUsername;

    private PasswordTextField txtPassword;

    private PasswordTextField txtConfPassword;

    private User user;

    public UserPanel(String id, final User user) {
        super(id);

        this.user = user;

        Form<User> frmCreateUser = new Form<User>("frmCreateUser") {

            /**
             *
             */
            private static final long serialVersionUID = 1L;

            @Override
            protected void onSubmit() {
                if (user.getId() == null) {
                    Long id = userDao.saveUser(this.getModelObject());
                    info("User #" + id + " has been created");
                } else {
                    Long id = userDao.updateUser(this.getModelObject());
                    info("User #" + id + " has been updated");
                }
            }

        };

        frmCreateUser.setModel(new Model<User>(user));
        add(frmCreateUser);

        txtUsername = new TextField<String>("txtUsername",
                new PropertyModel<String>(user, "username"));
        txtPassword = new PasswordTextField("txtPassword",
                new PropertyModel<String>(user, "password"));
        txtConfPassword = new PasswordTextField("txtConfPassword",
                new PropertyModel<String>(user, "password"));


        frmCreateUser.add(txtUsername);
        frmCreateUser.add(txtPassword);
        frmCreateUser.add(txtConfPassword);
    }

   the txtPassword and txtConfPassword fields display empty and so i have to
provide a password every time i edit the user.

 Kindly help

Regards

 Josh
