@gouessej - only one possible cause for GL_INVALID_ENUM is mentioned.

Oops, you're right, only the first one matches.

@jmaasing - still the same error

I think this is JOGL-related issue - I wrote similar code in LWJGL and it works.

Sorry but I use this method in Ardor3D JOGL 2 renderer and it works. Please follow Sven's advice, provide a tiny test case, maybe there is something obviously wrong.
