title: How to show popup on other popup?
body: <p>In my application, on some screen, I launch a popup. Depends on what button the user will click on this popup, another popup has to be launched. I use JDialog object to implement these popups. The issue is that the second popup doesn't show up (even though is use setVisible(true) and toFront()). It's created but I can't see it. I defined in its constructor the first popup as its owner. Anyone can help? </p>
