Unable to get value of the property '2': object is null or undefined

在bingmap开发的过程中调用_bingLayer.clear();会报“Unable to get value of the property '2': object is null or undefined”错误，百思不得其解，后来测试发现，执行如下代码之后再调用clear()方法就会出现这样的问题。
_bingLayer.push(pin2);_bingLayer.push(pin2);
就是添加了两个同样的pushpin对象，在clear()时就会报错了，如果你的程序报这样的错，检查一下你代码的逻辑吧，不过这也算是bingmap的一个bug吧。
