Problem dismissing a JPopupMenu

Question

I have a DropDownCalendar class that extends JButton. I am inserting a calendar(JPanel) into a JPopupMenu. The JPopupMenu is then invoked by the user when they click on the DropDownCalendar button. When a user clicks on a date in the calendar, the dateChanged() action is called which sets the selected date and then hides the JPopupMenu. After I hide the JPopupMenu, I then have to click TWICE on the DropDownCalendar button before the mouse event is fired again to redisplay the popup. The button never receives the first mouse click, but then receives the second. I think the popup is grabbing the first mouse click. Is popup.setVisible(false) the right way to dismiss the popup?
Here's the code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.text.*;
import java.util.*;
public class DropDownCalendar extends JButton {
     JLabel          dateLabel, arrowLabel;
     JPopupMenu jpm;
     SimpleCalendar scal;
     SimpleDateFormat dateFormatter;
     Dimension origin = new Dimension(0, 0);
     class MouseHandler extends MouseAdapter {
          public void mousePressed(MouseEvent me) {
               jpm.show(me.getComponent(), 0, me.getComponent().getHeight());
* DropDownCalendar constructor comment.
public DropDownCalendar() {
     super();
     // Set display format to "Mon, Dec 31, 2001"
     dateFormatter = new SimpleDateFormat ("EEE, MMM d, yyyy");
     // Button contains two JLabels. One for the date string and another
     // for the up/down arrow.
     dateLabel = new JLabel("", JLabel.LEFT);
     arrowLabel = new JLabel(" \u25BC", JLabel.RIGHT);
     setMargin(new Insets(0,0,0,0));
     setLayout(new BorderLayout());
     add(dateLabel, BorderLayout.WEST);
     add(arrowLabel, BorderLayout.EAST);
     addMouseListener(new MouseHandler());
     scal = new SimpleCalendar();
     scal.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
     dateChanged();
     jpm = new JPopupMenu();
     jpm.setBorderPainted(false);
     jpm.add(scal);
     dateChanged();     // Trigger this to initialize the date string in the button
private void dateChanged()
     // Set the date string the in the button
     dateLabel.setText(dateFormatter.format(scal.getSelection()));
     jpm.setVisible(false);

I am having the same problem. If the JPopupMenu is visible and the user clicks somewhere else on the JPanel to select something else, the JPopupMenu goes away but the MouseEvent doesn't get called on the JPanel. The only MouseEvent I get is mouseEntered. I put a PopupMenuListener on the JPopupMenu and tried requesting focus and transfer focus to my JPanel but that doesn't work. I have noticed that it does work if the same code it applied to a JTable or JTree?? On a JTable after the popupMenuWillBecomeInVisible a mouseReleased event is fired on the JTable and it looks like it is coming from java.awt.LightweightDispatcher.retargetMouseEvent. How do I get this to work just using a JPanel?
