AngularJS错误：$compile：multidir多指令资源争用

我试图将我的应用程序的一部分分成一个指令,但继续得到这个：

Multiple directives [tree (module: anbud),tree (module: anbud)] asking for template on:

这可能是由于：

Multiple directives requesting isolated scope.
Multiple directives publishing a controller under the same name.
Multiple directives declared with the transclusion option.
Multiple directives attempting to define a template or templateURL.

我有一个看起来像这样的观点：

<tree></tree>

该指令如下所示：

(function (module) {

    var tree = function () {

        return {
            restrict: "E",controller: "treeController",templateUrl: "/app/NSviewer/templates/parts/tree.html"
        };

    };

    module.directive("tree",tree);

}(angular.module("anbud")));

我的控制器更复杂：

(function () {
    'use strict';

    angular.module('anbud')
      .controller('treeController',['$scope','api','$log','localStorage','jwt',function ($scope,api,$log,localStorage,jwt) {

          // on successfull request
          function onJson(json) {

              //$scope.data = json;
              console.log($scope.data)

              // set default 
              $('#loading').hide();

              $scope.data = {};
              $scope.data[0] = {};
              $scope.data[0].c = "NS 3420";
              $scope.data[0].n = "2015";
              $scope.data[0].i = json.i;
              ;
          }

          // error getting json
          function onError(e) {

              console.log('error:');
              console.log(e);

              if (e.status === -1) {
                  throw 'Fikk ikke tak i server,sjekk internetforbindelsen din. [404]';
              } else if (e.status === 0) {
                  throw 'No connection. Verify application is running. [0]';
              } else if (e.status == 404) {
                  throw 'Fikk ikke tak i server,sjekk internetforbindelsen din. [404]';
              } else if (e.status == 401) {
                  throw 'Unauthorized [401]';
              } else if (e.status == 405) {
                  throw 'HTTP verb not supported [405]';
              } else if (e.status == 500) {
                  throw 'Internal Server Error [500].';
              } else {
                  throw 'Noe gikk galt. [' + e.status + ']';
              }
          }

          function onJsonPart(code,json) {

              console.log('Code: ' + code);
              console.log('json:');
              console.log(json);

              // validate JSON
              if (angular.isUndefined(json)) {
                  $log.error('Mottok ingen JSON for ns kode: ' + code);
                  console.log('Mottok ingen JSON for ns kode: ' + code);
                  return;
              }

              // check for code in root node in json 
              console.log('$scope.data:');
              console.log($scope.data);

              if (angular.isUndefined($scope.data)) {
                  $log.error('Scope data is not defined');
                  return;
              }

                  $log.error('NS koder er ikke lasted ned lokalt!');
                  return;
              }

              // loop gjennom layer 0 av treet
              // get object containing all ns codes
              var j = $scope.data[0];

                  }
              }

              $log.error('Fant ikke NS kode: "' + code + '"');

          }

          // get json part to append to tree
          $scope.get = function (code) {

              // Kun layer 1,AB - AV,BE3 til BE8,CD,CH,CY etc
              if (code.length > 3 || code.length < 2) {
                  $log.error('NS kode ikke godkjent!');
                  return;
              }

              api.get(code)
                   .then(
                       function (json) {
                           onJsonPart(code,json);
                       },function (error) {
                           onError(error);
                       }
               );
          };

          console.log('Getting JSON!');
          api.getFirstThreeLayers().then(onJson,onError);


      }]);

}());

不知道是什么原因造成这个问题..
