Hi all, thanks in advance for the help.

I'm trying to make calls to glCallList and glNewList by passing an integer variable as my parameter. 

That is, I have a static Integer id, and I call using gl.glCallList(id) and also gl.glNewList(id, GL.GL_COMPILE).

However, I get a big GL exception when I try this.  The only way I've found of not running into an error is if I pass an actual integer as a parameter (something like glCallList(5)).

Exception in thread "AWT-EventQueue-0" glGetError() returned the following error codes after a call to glNewList(): GL_INVALID_VALUE 
   at ObjMaker.drawObject(
   at Node.apply(
   at Node.apply(
   at SceneGraph.draw(
   at Main.display(

Can variables be passed to these methods?

UPDATE: Ah...0 isn't allowed.  That was the problem.  Thanks anyway  Roll Eyes

You should acquire the ids for your lists via glGenLists.
