title: "Duplicates in a repeater are not allowed" on ng-repeat
body: <p>I've got the following json data returned from a service request:</p>
  
  <pre><code>{
      "entries": [{
          "id": 2081,
          "name": "BM",
          "niceName": "bodmas"
          }]
      }, {
          "id": 8029,
          "name": "Mas",
          "niceName": "Masm"
          }]
      }],
      "count": 2
  }
  </code></pre>
  
  <p>And I am trying the following code in html to loop through this data:</p>
  
  <pre><code>&lt;option ng-repeat="entry in entries" value="{{entry.name}}"&gt;{{entry.name}}&lt;/option&gt;
  </code></pre>
  
  <p>I get the following error when I run the code:</p>
  
  <pre><code>Error: [ngRepeat:dupes] Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater: entry in entries, Duplicate key: string:c
  </code></pre>
  
  <p>Following is the code for my controller:</p>
  
  <pre><code>myApp.controller("MyController", ['$scope', '$http', '$log', function($scope, $http, $log){
         ...
  
         $http.get('https://myServiceURL').success(function(data){
                      $scope.entries = data;
          });
  }]);
  </code></pre>
  
  <p>Could somebody help me understand why am I getting that error?</p>
