Problem with restriction specifier in C++ AMP code

Question

Hi,
I'm using C++ AMP (I'm not that experienced with C++ and I'm new to AMP, so I have to stumble through this stuff) But I thought I had this code working, but now I'm getting the following error:
Error    1    error C3930: 'WRC_Raytracer::RaytracerRTC::RenderSceneWithAMP::<lambda_c13eb21eb34534d03d408733745bcf16>::operator ()' : no overloaded function has restriction specifiers that are compatible with the ambient
context 'Concurrency::_Parallel_for_impl'
Here is my parallel loop (cut down slightly to focus on the issue):
[code]
    parallel_for(0, 720 * 576, 1, [w, cBuffer, pixelDataView](int i) restrict(amp)
                // compute x and y for the given index
                float x = (float)(i % w);
                float y = (float)(i / w);
                // convert color from {0,1}f to {0,255}b
                int bInt, gInt, rInt;
                bInt = (int) (min(x/719.f, 1) * 255);
                gInt = (int) (min(y/575.f, 1) * 255);
                rInt = (int) (min(0, 1) * 255);
                // represent color data as (int)argb
                int pixelAsInt = (255 << 24) + (rInt << 16) + (gInt << 8) + bInt;
                // update pixelData element
                pixelDataView[i] = pixelAsInt;
[/code]              
Can anyone see what's wrong here ? As I said, I'm sure this was working yesterday, and I did something just before shutting down, and now it's not working.

The documentation for AMP mentions parallel_for_each:
http://msdn.microsoft.com/en-us/library/hh265136.aspx. Seems that you should redesign the code and use
parallel_for_each instead of parallel_for in case of restrict(amp).
