A DESCRIPTION OF THE PROBLEM :
When moving a component from a JPanel with a Cardlayout to another panel, the component get set isVisbile()==false

I have allso testet with 1.6.0 beta2 b73 with the same result

I asked the question on javadesktop: http://forums.java.net/jive/thread.jspa?threadID=13338

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the supplied code

First the label "I will get invisible soon" is in the center of the borderlayout
then it gets moved to the panel with the cardlayout
then i gets moved back to the panel with the borderlayout, making it not visible


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The label should have been visible in the center of the borderlayout
ACTUAL -
The label isVisble()==false

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public class CardAndSplitTest {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
JFrame f = new JFrame("Test add and remove");
f.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);

JPanel borderPanel = new JPanel(new BorderLayout());
JPanel cardPanel = new JPanel(new CardLayout());

JLabel aLabel = new JLabel("I will get invisible soon");
cardPanel.add(new JLabel("Botttom"), "a");
borderPanel.add(aLabel);
borderPanel.add(cardPanel, BorderLayout.SOUTH);
f.add(borderPanel);
f.setVisible(true);
cardPanel.add(aLabel, "b");
((CardLayout) cardPanel.getLayout()).next(cardPanel);
borderPanel.add(aLabel);
//aLabel.setVisible(true); // Why does this line of code have to be here?
f.pack();
}
});
}
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
I aLabel.setVisible(true) gets called after the label has been moved, it will work as expected
