Flash - InteractiveScene3DEvent Not Firing In Papervision BasicView

I'm using BasicView to setup my PV3D scene, and the scene itself works fine (3d carousel of movie posters) but the InteractiveScene3DEvent is not firing when a poster is clicked or moused over. I set my viewport to interactive... twice.
view = new BasicView(stage.stageWidth,stage.stageHeight,true,true);
view.viewport.buttonMode = true;
view.viewport.interactive = true;

And here is the part of the loop where it the event listener is added.
var mm:filmsPoster = new filmsPoster();
mm.loadIMG(image);
var mat:MovieMaterial = new MovieMaterial(mm);
mat.interactive = true;
mat.animated = true;
mat.smooth = true;
mat.doubleSided = true;
mat.name = filmName;
mat.addEventListener(InteractiveScene3DEvent.OBJECT_CLICK, posterClick);
