[news.eclipse.technology.albireo] JOptionPane and dispose() problems

[Stephan Nagy <stephan.nagy@xxxxxxxxx>]

Hi,

We recently switched from our much hacked on EmbeddedSwingComposite to 
Alberio, and I'm happy to say many of the problems we had experienced 
have gone away.  However, we have encountered a new problem that we are 
a bit puzzled by.

When we spawn JOptionPane from our SwingControl we get the stack at the 
end of this email dispose.  We hacked on the JOptionPane and replaced

dialog.show();
dialog.dispose();

with

        dialog.setVisible(true);
        dialog.setVisible(false);
        SwingUtilities.invokeLater(new Runnable() {public void run() {
            dialog.dispose();
        }});

which makes the problem go away, but isn't really an acceptable 
solution.  Any thoughts or ideas on how we might avoid the problem?
