WebGL asset bundles collider problem

I try to convert my webplayer project into webgl. I have problem when try to load asset bundles with www class. When load all browser give me error like this: Could not produce class with ID 65 I see that code is relative to collider, so i delete collider from gameobject, resave asset bundle (without collider) and now app work. Somebody can help me? I need collider attached to model... S.
