Vertex color indexes are not exported correctly

[GoogleCodeExporter]

In GeometryPolygonExporter::writeVertexIndices, the Idx from vertex attributes 
is used to lookup color set name despite the fact it is always set to -1. The 
result is index is always 0. I've hardcoded the index to be 0 for color, and it 
fixes the problem, but only works with on colorset.

Any ideas on how to fix it properly?

Code that behave incorrectly :
case COLLADASW::COLOR:
{
    MString& colorSetName = mColorSetNames[vertexAttributes.getIdx()];
    int colorIndex = 0;
    {
#if MAYA_API_VERSION >= 700
        fnMesh.getColorIndex ( polyIndex, iteratorVertexIndex, colorIndex, &colorSetName );
#else
        fnMesh.getFaceVertexColorIndex ( polyIndex, iteratorVertexIndex, colorIndex );
#endif
    }
    primitivesBasePoly->appendValues ( colorIndex );
}
break;
