#238 glCallList fails on nurbs surface

[Anonymous]

molehill.c compiles and renders fine
http://www.opengl.org/resources/code/samples/mjktips/grid/molehill.c

however, upon running molehill.py
/usr/local/lib/python2.6/dist-packages/PyOpenGL-Demo/GLUT/molehill.py

i get the following error, and the window does not display

Traceback (most recent call last):
File "_ctypes/callbacks.c", line 295, in 'calling callback function'
File "molehill.py", line 46, in display
glCallList(THE_LIST)
File "/usr/lib/pymodules/python2.6/OpenGL/error.py", line 208, in glCheckError
baseOperation = baseOperation,
OpenGL.error.GLError: GLError(
err = 1282,
description = 'invalid operation',
baseOperation = glCallList,
cArguments = (1L,)
)

similar code that uses display lists with nurbs curves DOES work, somehow.
