[away3d] loading .dae make me crazy...

[Colir]

Hi the team,

i'm trying to load a .dae file with away3d, and i have always an error
with the loading  of the texture...

TypeError: Error #1009: Il est impossible d'accéder à la propriété ou
à la méthode d'une référence d'objet nul.
        at away3d.loaders::Loader3D/loadTextures()
        at away3d.loaders::Loader3D/onGeometryComplete()
        at flash.events::EventDispatcher/dispatchEventFunction()
        at flash.events::EventDispatcher/dispatchEvent()
        at flash.net::URLLoader/onComplete()

i don't understand, because my .dae haven't texture > its  a simple
cube, just for try
and i load the collada like this :
     objLoader = Collada.load(objPath,{autoLoadTextures :
false,scaling:0.005});
     scene.addChild(objLoader.handle);

however i have always this error...i just don't understand... i 've
already load succesfully some .dae with previous version of away3d and
with texture...

thanks very very much for your help
