Problem with ScrollView and CocosBuilder

Hello everybody.
I use CocosBuilder alpha 5 and Cocos2dx-JSB 2.1.4. I add ScrollView to my scene using CocosBuilder, next on the right panel I select ccb file as a container. After run this scene I have error from XCode (CocosPlayer):

2013-08-07 16:08:30.304 CocosPlayer[9238:c07] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Argument must be non-nil'

So I tried to add ScrollView to my scene “manually” with code:

scrollView = cc.ScrollView.create(new cc.Size(800, 5000), cc.Layer.create());

and I have following error in result:

cc.ScrollView is undefined

Could you help me guys?
