getting error `Uncaught TypeError: Cannot read property '$$hashKey' of undefined(…)`

[GuyMograbi]

I traced the source to be in objectTableCtrl

 $scope.ifSelected = function(item) {

      if (!!$scope.selectedModel && $scope.select === 'multiply') {
        return ctrl._containsInSelectArray(item);
      }else {
        return item.$$hashKey == $scope.selectedModel.$$hashKey;
      }
    };

I will have a PR soon
