attachmentSimple 放在list 下使用的问题

yasin

我把attachmentSimple 放在list 下使用时，每次打开时都报
TypeError: Unable to process binding "component: function (){return {ref:ref('fSetUpImg'),name:'$model/UI2/system/components/justep/attachment/attachmentSimple'} }"
Message: Cannot read property 'length' of null

后台不报错，直接使用就没有问题，不放list里用。
