Problem with Controller and a Service

[mark goldin]

Service:

var myModule = angular.module('myApp', []);

myModule.factory("AirportService", function ($http, $q) {

    return {

        getData : function(){

            var deferred = $q.defer();

            var response = $http.get("griddata.json");

            response.success(function (data) {

                deferred.resolve(data);

            });

            response.error(function (data) {

                alert('Error 123');

            });

            // Return the promise to the controller

            return deferred.promise;

        }

    }

});

Controller:

var myModule = angular.module("myApp", []);

myModule.controller('AirportControllers', [function ($scope, $http, AirportService) {

    AirportService.getData().then(function(data) {

        $scope.agents = data;

    });    

}]);

No matter what I do I get:

TypeError: Unable to get property 'getData' of undefined or null reference

 at Anonymous function (http://..../angular/controllers.js:3:5)

Any idea?

Thanks

Hi Mark

You are redefining your module in stead of just getting a reference.

angular.module("myApp", []); defines a module
angular.module("myApp"); gets a reference to the same module. (notice the absentt ,[])

This is the root cause of your problem

Yes, that was a problem. Thanks

Iam getting the  TypeError: Unable to get property 'then' of undefined or null reference when try to use the below code.

var app = angular.module(,$scope,['tableSort']);

   //Get All the Dash Board Services

   app.factory('ResourceDetailsFactory', function ($http) {

       return {

           GetResources: function (ResourceType, Status) {

               //since $http.get returns a promise,

               //and promise.then() also returns a promise

               //that resolves to whatever value is returned in it's 

               //callback argument, we can return that.

               $http.post('dummay.aspx/Getmethod', { resource: ResourceType, status: Status }).then(function (result) {

                             return result.data;

               });

           }

       }

   });

 ResourceDetailsFactory.GetResources(ResourceType, Status).then(function (data) {

         

        });

Any one can help me what wrong in the 

ResourceDetailsFactory.GetResources(ResourceType, Status).then(function (data) {}

Thanks
