dojox.gfx3d fails in Silverlight: "null or not an object"

[Erik Demaine]

Attached is a very simple beginning of a dojox.gfx3d test: all it does is create a gfx surface and create a viewport within. But in Silverlight on IE, something seems to be wrong with the object nature of the surface, because the createViewport method call isn't succeeding (presumably because it's not happy with the value of 'this'? I'm not sure). Here's the console log:

LOG: surface: [object Object]
LOG: type: object
LOG: createViewport: function(){
var _81=this.createObject(dojox.gfx3d.Viewport,null,true);
_81.setDimensions(this.getDimensions());
return _81;
}
(Error) 'null' is null or not an object

The offending line is var viewport = test.createViewport (); I've had errors within the Dojo code before (caused by my code), and IE correctly reports the line number within dojo.js. So it seems to really failing on the call itself, not within the call. Strange.
