Ed,

unfortunately you didn't show QueryWizardDialog's jbInit(), I assume this is
the method where you are a) applying the CardLayout and b) add the JPanels
to the Container that uses the CardLayout.

Basically it's like that:
//add a panel
cardPanel.add(aPanel, someString); //someString identifies the component
being added - use it for show(...) later!
...
//switch card
CardLayout cl = (CardLayout)(cardPanel.getLayout());
cl.show(cardPanel, someString);

Good luck,
Torsten
