Возможно ли иметь CardLayout на CardLayout

Я на самом деле работаю над Java-программным обеспечением, и я стараюсь разместить макет карты на макете карты, вот мой код (я упростил его, просто чтобы показать вам проблему): первый cardLayout икнопка для навигации между всеми cardLayout 

 CardLayout cardLayout = new CardLayout();
    JPanel PrimaryCard = new JPanel();
 [...] 
  PrimaryCard.setLayout(cardLayout);
    PrimaryCard.add(creer, "creer");
    PrimaryCard.add(modifier, "modifier");
    PrimaryCard.add(acceuil, "acceuil");
 [...]
 top.add(Acceuil);
    Acceuil.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
         cardLayout.show(PrimaryCard, "acceuil");
        }
    });

Второй CardLayout 

CardLayout CreationCardLayout = new CardLayout();
    JPanel creationcard = new JPanel();
[...]
`creationcard.setLayout(CreationCardLayout);
    creationcard.add(CDevis, "CDevis");
    creationcard.add(CObjectifs, "CObjectifs");
    creationcard.add(CClient, "CClient");`
[...]
 creer.add(ButtonCDevis);
    ButtonCDevis.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            cardLayout.show(creationcard, "CDevis");
        }
    });

Но когда я нажимаю вторую кнопку, чтобы перейти ко второй CardLayou, у меня появляется этот код ошибки:

cardLayout.show(creationcard, "CDevis");

должно быть 

CreationCardLayout.show(creationcard, "CDevis");
...
