[JAVA3D] NullPointerException

[Demetrius Comes]

Hi all,   Using immediate mode rendering I get a null pointer exception from setModelTransform() of a GraphicsContext3D. Specifically line # 874.  This exception only occurs if I create the virtual universe myself (ie. not using SimpleUniverse)   Below I have how I am creating the Universe.  Does anyone have any ideas or is the source code for Java3d available so I can atleast see the line that is causing the exception.  The other kinda weird this is that I can draw on the GraphicsContext3D I just can't set the transform matrix.   snip------------------------------------------------------------------------------------------------------------------------- canvas = new Canvas3D(null);  canvas.setDoubleBufferEnable(true);  canvas.stopRenderer();  add("Center",canvas);    universe = new VirtualUniverse();  view  = new View();  view.setPhysicalBody(new PhysicalBody());  view.setPhysicalEnvironment(new PhysicalEnvironment());  ViewPlatform vp = new ViewPlatform();  view.attachViewPlatform(vp);  view.addCanvas3D(canvas);  view.setCompatibilityModeEnable(true);  Locale locale = new Locale(universe);  gc = canvas.getGraphicsContext3D();   ------------------------------------------------------------------------------------------------------------------------------------- thanks in Advance Demetrius
