I just downloaded and installed the controlP5 library (v0.6.12) onto my Mac by putting in the ./Documents/Processing/libraries folder. When I run the ControlP5controllerOnTop3D.pde example, it returns the following error message:
java.lang.NullPointerException

I am using Processing 2.0a4 because I need to use JSyphon. I intended to use controlP5 to add a hideable menu that would hover over a 3D sketch. Does controlP5 work in Processing 2.0a4? There were a couple of other examples that returned the same error. I didn't change the code in any of them.
