Hi,  
I’m having an issue with the controlP5 Library in processing.

> `setSwitch(true)`

I’m using this line of code to make the button `toggle`. it works but I’m getting this error message.

```auto
 controlP5.ControlBroadcaster invokeMethod
 WARNING: java.lang.IllegalArgumentException: wrong number of arguments

```

the program doesn’t crash but it’s slowing down.

and this is my code…

```auto
button_settngs.addButton("settings")
    .setPosition(50, 50)
    .setValue(0)
    .setImages(settings_button_img)
    .updateSize()
    .setSwitch(true)
    ;

```

If i make setswitch(false) everythis works fine. imean no error message.

thanks in advance.
