In what way can I avoid disapperaing the item of JPopupMenu?

[Oleg Vasylenko]

I have a such code below to create and show popupmenu.
Popupmenu appear when I need. I choose menu "Menu1" and object JPanel appear as I wish. JPanel contains JFormattedTextField,JComboBox and JButton.
When I try to choose the item from JComboBox the main popup menu disapper.
What should I do to prevent such behaviour?
Thanks a lot!

   
JPopupMenu popup = new JPopupMenu();
JMenu menu = new  JMenu("Menu1");
JPanel aPane = new JPanel();
aPane.add(new JLabel("Enter time:"));
try{
 MaskFormatter formatter = new MaskFormatter("##:##");
 formatter.setPlaceholder("#");
 JFormattedTextField time = new JFormattedTextField(formatter);
 aPane.add(time);
}
catch(ParseException ex)
{
 return;
}

aPane.add(new JLabel("Choose the name"));
aPane.add(new JComboBox(new String[]{"Ann","Kat"}));
aPane.add(new JButton("OK"));
menu.add(aPane);
popup.add(menu);

JMenuItem item=new JMenuItem("other item menu");
menu.add(item);

popup.add(menu);
popup.show(e.getComponent(), 100,100);

Well - there is a PopupMenuListener, that has a method, popupMenuWillBecomeInvisible() - this is called just before the popup menu disappears. I'd guess that you could interrupt this and stop it from happening.

However - it doesn't sound like the best approach - is there a particular reason that you need to use a JPopupMenu for it, rather than something else, like a JDialog?
