I'm having problems with openGL display lists using gl4java. I'm not sure
if this is a java/gl4java specific question, or if it applies to openGL in
general.

I'm trying to create display lists lazily, ie only compiled as needed. This
is because I have a few things to draw that are unlikely to be needed, but
if they are needed are going to have to be drawn many times. I realise that
once a display list has been created it may not be changed, but thought I
could create them anytime.

so in display() I have:

private static final int LIST_NO = 1;

if( gl.glIsList( LIST_NO ) )
{   gl.glCallList( LIST_NO );
}else
{   System.out.println( "defining new list for " + LIST_NO );
   gl.glNewList( LIST_NO , GLEnum.GL_COMPILE_AND_EXCECUTE )
       gl.glBegin( //... yada yada
       //... yadda yadda
       gl.glEnd();
   gl.endList();
   if( gl.glIsList( LIST_NO ) )
       System.out.println( "confirmed list created" );   
}

Now then, I get "defining new list for 1" and "confirmed list created"
printed to standard out on EACH repaint, not just once, so OGL it is
creating the list each time and then discarding it before the next call to
display()

If I create a display list in init() I don't have this problem - they are
held until I delete or replace them; But I can't declare all my lists there
- my program doesn't know how every object will look at initialization.

Please could somebody help me out here, I'm sure I'm missing somthing
simple!
