bex5 3.8版本，用的attachmentSimple组件，页面加载时就会报错并关闭页面
attachmentSimple组件报错内容如下：

1. core.min.js:71 Uncaught TypeError: Unable to process binding "style: function(){return {backgroundImage:($model.previewPicture.bind($model,$object))()} }"
   
2. Message: Cannot read property 'get' of undefined

如果换成attachmentPC，报错内容如下

1. Uncaught TypeError: Unable to process binding "style: function(){return {opacity:$model.$access.get() % 4 >= 2 || $model.$state.get() =='remove'?'1.0':'0.5',backgroundImage:($model.previewPicture.bind($model,$object))()} }"
