$resource transformResponse not working

Got a simplified `$resource` example here (adapted from Angular site): ``` angular.module('project', ['mongolab']); function ListCtrl($scope, Project) { $scope.projects = Project.test(); } angular.module('mongolab', ['ngResource']). factory('Project', function ($resource) { var url, dfParams, actions; url = 'https://api.mongolab.com/api/1/databases' + '/angularjs/collections/projects/:id'; dfParams = { apiKey: '4f847ad3e4b08a2eed5f3b54' }; actions = { test: { method: 'GET', isArray: true, transformResponse: function (response) { // line is never getting called console.log('transforming'); return response; } }; var Project = $resource(url, dfParams, actions); return Project; }); ``` The question is that the line `console.log('transforming')` is never getting called. Why is that? Everything else works fine. Live fiddle here.
