$ scope未从异步错误回调更新

Question

我正在尝试从promise错误回调中更新$scope，如下所示：

 var reportErrors = function (error) {
      $scope.state['save-mappings']='update';
      ...
 }

 myService.myMethod().then(postProcess).catch(reportErrors);

但是，$scope未正确更新且相应的ng-if未更新...

<div ng-if="state['save-mappings'] === 'update'">

有人可以帮忙吗？

编辑：postProcess功能：

var postProcess = function (data) {
    var associateMediasPromise = function () {
        return SupplierImportService.associateMedias($scope.getLink($scope.ngDialogData.import.links, 'associate-medias'));
    };
    var matchArticlesPromise = function () {
        return SupplierImportService.matchArticles($scope.getLink($scope.ngDialogData.import.links, 'match-articles'));
    };
    var updatePostProcessPromise = function () {
        $rootScope.$broadcast('init-headers');
        $rootScope.$broadcast('update-import', data.data);
        $rootScope.$broadcast('change-articles-page');
        $rootScope.$broadcast('update-statistics');
        $scope.setPopinState('save-mappings', 'done');
    };
    return associateMediasPromise()
        .then(matchArticlesPromise)
        .then(updatePostProcessPromise);
};

来自myMethod的

：

var myMethod = function () {
 return $http.post(...);
};
