angular.js deferred doesnt work in callback

[Dima Vernovsky]

Hello all! 

Maybe somone could help me:

I'm trying to use promises API to call server for json, now then i use resolve inside callback the promise doesn't work:

 .service('movieGetter', ['$q', '$timeout', function ($q, $timeout) {
    this.getData = function () {
        var deferred = $q.defer();
        $timeout(function(){
            mock.getData(function(data){
                deferred.resolve(data);
            });
        }, 2000);

        return deferred.promise;
    };
}]);

but, when i just call resolve from within the timout function everything works fine:

 .service('movieGetter', ['$q', '$timeout', function ($q, $timeout) {
    this.getData = function () {
        var deferred = $q.defer();
        $timeout(function () {

            deferred.resolve('test');
        }, 2000);

        return deferred.promise;
    };
}]);

Somone have eny idea maybe?

Thanks!

I faced a similar problem a while back. My solution was to inject $rootScope into your service and after your resolve the promise in the success callback of mock.getData(), call $rootScope.$apply();

Something like this:

$timeout(function(){
            mock.getData(function(data){
                deferred.resolve(data);

                $rootScope.$apply();
            });
        }, 2000);
