Cardlayout Problem

I'm trying to get a card layout to work to display my multiple panels so that
I can use it in a project I am working on. I have a JFrame and on that
JFrame is a JPanel that will load the cards. I can get all of the cards that
are within the same class to load fine. However I have quite a few panels
that are very different and I don't want to stick it all into one class.
Right now I can get the card (panel) from another class to load fine, but
when I click its button to load another card that is where the program dies.
I put a print statement in the function just to make sure the program is
getting there and it is, but it just isn't loading the new panel. 

Here is my code for the frame where I can get everything to load fine:


/*
 
package layout;

import javax.swing.*;
import java.awt.*;

public class CardLayoutFrameTest extends javax.swing.JFrame {
    
    /** Creates new form CardLayoutFrameTest */
    public CardLayoutFrameTest() {
        initComponents();
        initOtherClassComponents();        
    }
    
    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.

Here is my code for the other class that I can get to load, but can't get
anything to load when I push its button:

Hopefully that isn't too confusing, thanks for any suggestions in advance.
