我下载了github里的example-cases，然后想使用里面的pageview，结果浏览器运行时就出错，信息如下：
Can not find class “cc.PageViewIndicator” （未知）
Can not find class “cc.PageView” （未知）
Sorry, the component of “New PageView” which with an index of 0 is corrupted! It has been removed. cocos2d-js-for-preview.js:22584:25
Corrupted component value: Object { _$erialized: Object } cocos2d-js-for-preview.js:22585:25

团队能否修复下这个错误。
