cocosbuilder don't work in js


hi, i got a message as “Skipping selector ’’ since no CCBSelectorResolver is present.” , i’m using cocosbuider 3.0 and cocos2d-x 2.1 beta. as i traced, the problem it that the owner object isn’t casted to CCBScriptCallbackProxy, just want know, is there far way to finish the feature or only need add few piece of codes?

thank you
