BoxLayout - can't be shared run time error

Hi!

I get this error:

Exception in thread "AWT-EventQueue-0" java.awt.AWTError: BoxLayout can't be shared.

I have a main panel, with all the UI components working fine. When I press a button I display a custom dialog. I try to set a JPanel as the dialog's content pane. Then I try to set up the BoxLayout as the layout manager for the JDialog.

But I get that awful error.

Can you please tell me why?

I enclose some code too:

JDialog sortDialog = new JDialog(frame, "Se sorteaza");

BoxLayout layout = new BoxLayout(sortDialog, BoxLayout.Y_AXIS);

sortDialog.setContentPane(new JPanel(layout));

sortDialog.pack();

sortDialog.setVisible(true);
