glMap2f error GL_INVALID_VALUE 1281

I can’t make run correctly glMap2f though glMap1f runs correctly. Just after calling glMap2f I get the error 1281. I tried different combinations, for the latest I used only 4 points (GeForce limits : 8 eval points) : glMap2f(GL_MAP2_VERTEX_3,0.0,1.0,3,2,0.0,1.0,6,2,pointControl) pointControl = Array(-10,0,0,10,0,0,10,10,0,-10,10,0). Any idea ?

It s ok with glMap2d, bad data format…
