编辑器中场景打开失败

Creator 2.x
#1

游戏运行时有类似这样的提示：

CCDebug.js:249 Failed to construct a dummy instance of the “RoomListScene2” class using new behind the scenes. This is for getting default values declared in TypeScript. Please ensure the class will be able to construct during script’s initialization. TypeError: Cannot read property ‘32’ of undefined.

。。
但运行没问题。
但是在编辑器中打开这个场景会失败，错误也是说 annot read property ‘32’ of undefined.
然后我手动打开fire文件，把32号这个component删掉了。删除library目录，重启creator，还是这个问题。

怎么破。。
我看了git记录，这个场景近期没有任何改动。

找到原因了。是代码问题。
场景节点挂载的component里有个属性，这个属性我是直接定义时就初始化的，是个类。类的构造方法里需要访问一些数据，游戏没运行自然是没有这个数据的，所以报了undefined :disappointed_relieved: :disappointed_relieved:

。。。这, 这样不好吧。
而且运行时的警告也是很搞笑 。
提示我属性定义的有问题。类似这样。
// Before:
@property(…)
value;
// After:
@property(…)
value = 0 labelPeach

楼主后来怎么解决的啊？
