Angular Unit Test Jasmine Spy error - angularjs

Question

The following controller is getting a TypeError: 'undefined' is not a function (evaluating sessionService.getCurrentPlace()). I have a Mock Service with that method being spied on. The other method on the mock service works fine. I've tried .AndReturns({..}) on the spy as well as .AndCallThrough() but no luck. Any idea what I'm missing, or am I going about this wrong? Much Thanks!
CONTROLLER:
'use strict';
angular.module('wallyApp')
.controller('addGatewayCtrl', function ($scope, $location, $filter, sessionService) {
/*
private members
*/
//set scope from session data
$scope.processSession = function (places) {
$scope.currentPlaceId = sessionService.getCurrentPlace();
if (!$scope.currentPlaceId) {
$scope.currentPlaceId = places[0].id;
}
$scope.place = $filter("getById")(places, $scope.currentPlaceId);
$scope.ready = true;
};
/*
setup our scope
*/
$scope.currentPlaceId = null;
$scope.place = {};
$scope.videoSrc = "/videos/gateway-poster.gif";
$scope.loaded = true;
/*
setup controller behaivors
*/
//set video or gif to show or hide video
$scope.setVideo = function () {
$scope.videoSrc = "/videos/gateway.gif";
};
$scope.setPoster = function () {
$scope.videoSrc = "/videos/gateway-poster.gif";
};
//initialize scope
$scope.setVideo();
//submit form
$scope.continue = function () {
$location.path("/setup/pair-gateway");
return false;
};
//cancel
$scope.back = function () {
$location.path("/setup/plan-locations");
return false;
};
//wifi
$scope.gotoWifi = function () {
$location.path("/setup/wifi");
return false;
};
/*
setup our services, etc
*/
//get our places from the cache
sessionService.get("places").then(function (places) {
if (!places || places.length < 1) {
sessionService.refreshPlaces(); //Note we don't care about the promise as our broadcast watch will pick up when ready
} else {
$scope.processSession(places);
}
}).catch(function (error) {
//TODO:SSW Call Alert Service??
});
//Watch broadcast for changes
$scope.$on("draco.placesRefreshed", function (event, data) {
sessionService.get("places").then(function (places) {
$scope.processSession(places);
});
});
});

So I figured it out. With nested deferred's you have to call $scope.$apply() in between. The following fixed it up (along with a few minor changes to the mock data responses, but those were trivial):
//resolve promises
activityMessagesDeferred.resolve(mockActivityMessages);
$rootScope.$apply();
$rootScope.$broadcast("draco.sessionRefreshed");
activityCountDeferred.resolve(mockActivityCount);
$rootScope.$apply();
placesDeferred.resolve(mockPlaces);
activityListDeferred.resolve(mockActivities);
$rootScope.$apply();
