bug with sceneType ??

Hi,
I am having a problem when creating a scene manager passing arg ST_INTERIOR. It seems like it doesn't change anything and create a default scene manager no matter what scene type I give.

If I pass "BSPSceneManager" as a typeName for the creation, it works, but I can't use that since I do not want the autocreationwindows when I am initializing root :
so if I pass false for initializing root, and that I use BspSceneManager for the scenemanager creation, I got this :
"No factory found for scene manager of type 'BspSceneManager"

now, if I give any kind of SceneType.ST_WHATEVER like :
mRoot.CreateSceneManager(SceneType.ST_INTERIOR);
A default scene Manager is created :S

Any idea ?
Cheers!
