Cube Mapping with OpenGL in Processing 2.07b

i wrote a small sketch demonstrating what should happen in in processing 1.5. it is basically the same functionality as in the working version of the thread above. this is what it looks like:

i want to achive the same effekt (cube mapping) with processing 2.0. and since the glgraphics library from of andres should be included mostly into processing 2.0 it should be no problem- i just dont know enough of the inner workings of processing with opengl in combiation with shaders to make it work. my status looks like this: (you can see the back strokes of the sphere that should have the reflections of the cube map on it):

maybe somebody can help me to get this to work. i zipped up both versions for you to debug here:
