md联系芯片css不工作

Question

我正在使用md联系人芯片，我的模板看起来像这样

 <md-chips ng-model="ser" md-autocomplete-snap
              md-require-match="true">
      <md-autocomplete
        ng-disabled="autoCompleteOptions.isDisabled"
        md-no-cache="autoCompleteOptions.noCache"
        md-selected-item="si"
        md-search-text="searchText"
        md-items="sellable in getSellableByFilter(searchText)"
        md-min-length="1"
        md-item-text="sellable.name"
        placeholder="Search for a Service/Package here"
        md-select-on-match="true",
        >
      </md-autocomplete>
      <md-chip-template>
        <span>
          <strong>{{$chip.name}}</strong>
        </span>
      </md-chip-template>
    </md-chips>

搜索工作正常但是当我选择一个项目时，它看起来只是输入字段而且没有像css这样的芯片。

我该如何解决这个问题？

我也试过使用md接触芯片，但问题仍然存在。

我在控制台中看到

错误消息

你的模型必须是Array类型，并且可能在你的控制器中你没有将它初始化为任何东西（它是未定义的）。

ser = []
