Thx Frank :-) Hmmm, do you have a example scene or a render :-?
Maybe the error is, that you try to evaluate to early or non existing things. For example if you try to evaluate the "occlusion-shader", you must add maybe normal "Surface-Properties" like color and Illumination to get a proper result. A second mistake is possibly that you've tried to evaluate, let's say Illumination on a analtic sphere and you've used a "default" map material and not a "spherical" map material, then you do not have a proper material coordinate system for evaluating :-?
