如何在ng-repeat或循环中使用md-chips

Question

我收到错误 TypeError：无法读取属性＆＃39; some＆＃39;未定义的      在

    </div>

循环未定义，必须创建所有选定值的afinal数组。下面是每个输入字段只占用一个芯片的代码。

HTML

(function () {
    'use strict';

    angular
        .module('app')
        .controller('chipsCtrl', chipsCtrl);

    /* @ngInject */
    function chipsCtrl($q,$timeout) {
        var vm = this;
        vm.selectedItem = null;
        vm.searchText = null;
        vm.mistakes = loadMistakes();
        vm.selectedMistakes = [[],[]];
        vm.transformChip = transformChip;
        vm.searchTextChange = searchTextChange;
        vm.removeChip = removeChip;

        /**
         * Return the proper object when the append is called.
         */
        function transformChip(chip) {
            console.log(chip);
            // If it is an object, it's already a known chip
            if (angular.isObject(chip)) {
                return chip;
            }
            // Otherwise, create a new one
            return { name: chip, id: 1 }

        }
        vm.placeholder = "Select Mistake Type";

        function searchTextChange(index) {

            //console.log(vm.selectedMistakes);
            vm.searchText = null;
            if(vm.selectedMistakes[index]){
                vm.placeholder = (vm.selectedMistakes[index].length > 0) ? "Just 1 allowed" : "Select Mistake Type";
            }

        }

        function removeChip(index){
            vm.placeholder = (vm.selectedMistakes[index].length > 0) ? "Just 1 allowed" : "Select Mistake Type";
        }

        function loadMistakes() {
            return  [
                {
                    'name': 'Simple',
                    'id': 1
                },
                {
                    'name': 'Conceptual',
                    'id': 2
                },
                {
                    'name': 'Silly',
                    'id': 3
                },
                {
                    'name': 'Visual',
                    'id': 4
                },
                {
                    'name': 'dilemma',
                    'id': 5
                }
            ];
        }
    }
})();

控制器

vm.selectedMistakes = [
  [
    {
      "name": "Conceptual",
      "id": 2
    }
  ],
  [
    {
      "name": "Simple",
      "id": 1
    }
  ]
]

预期输出

webView.setWebViewClient(new WebViewClient(){
        @Override
        public void onLoadResource(WebView view, String url) {
            super.onLoadResource(view, url);
            Log.d(TAG, "onLoadResource: " + url);
        }
    });

我对这两个输入都有触发值
