One-line summary [问题简述]

dataset 在 dataset.source 为空数组的时候,在 DefaultDataProvider 方法中因为 sourceFormat 被判定为 unknown 导致继承不了 count 方法,然后在 listProto.initData 中会调用 count 方法导致抛出错误,导致后续无法更新视图

  • Browser version [浏览器类型和版本] : Chrome/66.0.3359.181
  • OS Version [操作系统类型和版本]: Mac OS X 10_13_4

Expected behaviour [期望结果]

    source: []
