I keep getting java.lang.NullPointerException for the following code:

 ScalarMap shape_map = new ScalarMap(x,Display.Shape);
 VisADGeometryArray[] shapes;
 shapes = new VisADGeometryArray[max_points];
 for(int i=0;i<max_points;i++)
  shapes[i] = makeCube();
 ShapeControl shape_control = (ShapeControl) shape_map.getControl();
 shape_control.setShapeSet(new Integer1DSet(1)); // ERROR on this line

Do I have to seperately set the values for Integer1DSet?
