ControlP5 I am misunderstanding something

Hello, I am a rusty programmer.. I was wondering if someone would be kind enough to point out my misunderstanding. I am setting up two windows.. one running a temperature graph and one containing the controls. There are three temp stations. Everything was running along smoothly until I tried using the setOn() or setOff() button functions. I think I am misunderstanding something basic about how the ControlP5 library works.

There is a lot of irrelevant code... I think this should be enough to help me...if you so choose.

        `
        SecondWin sw;

        void settings() {
           size(1100, 850, JAVA2D);
        }

        void setup() {
           sw = new SecondWin(this, 700, 400);  //second Window (Control Panel)
        }
        void draw() {
        }

        public class SecondWin extends PApplet {  // code for window

          int w, h;
          PApplet parent;
          ControlP5 cp5;


            public SecondWin(PApplet _parent, int _w, int _h) {
               super();
               parent = _parent;

               w = _w;
               h = _h;
               PApplet.runSketch(new String[]{this.getClass().getName()}, this);
            }

            public void settings() {
               size(w, h);
            }

            public void setup() {

            cp5 = new ControlP5(this);

              cp5.addButton("VS2")
                            .setImages(icons[0], icons[0], icons[10])
                            .updateSize()
                            .setPosition(10, 10)
                            .setSwitch(true)
                            .setId(50)
                            .plugTo(parent, "VS2");
        }

          public void draw() {
          background(255);
          fill(0);
         }
         public void controlEvent(ControlEvent theEvent) {
              if (theEvent.isController()) {
                  println(((Button)cp5.getController("VS2")).isOn());
       //         ((Button)cp5.getController("VS2")).setOn();       ########## PROBLEM  ######
            }

        }
}
`

As mentioned, I left out a lot of code. I have been fighting this for a few hours...so a lot of this code I have stolen from online sources and Frankenstein'd here.

As is, it runs with no errors and hitting the VS2 button prints out the proper false and true values. When I un-comment the ((Button)cp5.getController("VS2")).setOn(); and then hit the button, I get a stream of multiple 'trues' printed to console and

If it is something really basic I am missing, even throwing me a reference page address would be appreciated.

Thanks!
