replace scene with transition always call a null lua function

(LuaScriptModule) Unable to execute scripted event handler:handler_name == NULL

simple test code:

local newScene = cocos2d.CCScene:node()
cocos2d.CCDirector:sharedDirector():replaceScene(cocos2d.CCTransitionFade:transitionWithDuration(0.5,newScene))

actually, this warning didn’t caused any big problem until now.
