Getting the dreaded module not instantiated error, but everything appears right - angularjs

Question

I'm getting the error: "[$injector:modulerr] Failed to instantiate module myApp due to: ReferenceError: isUndefined is not defined". It suggests I misspelled something or forgot to included dependencies. I've checked and all my scripts are included, all my spelling is correct, and I don't think I've left any dependencies out. I've got a lot of other controllers structured very similarly to this one with no problem, but now two of my most recent added controllers/views are giving me the error. I stripped out all the logic to make sure I wasn't doing something inadvertent, but still no dice. I'm including the module it says is undefined, a similar controller that works, and the controller (now stripped of all logic except a console.log) for the new view that doesn't work. Any ideas?
The "undefined" module (with a number of logic taken out for brevity):
var app = angular.module("myApp", ["ngRoute", 'ngAnimate', 'angular-growl', 'ui.select', 'ngSanitize', 'ui.bootstrap', 'ui.bootstrap.datetimepicker']);
var HeaderCtl = function($scope, $location) {
console.log('inside HeaderCtl : ' + $scope.isLoggedIn);
$scope.tabSelected = function(tabname) {
console.log('Server Parameter :' + $scope.tabname);
$location.path("/" + $scope.tabname);
}
}
app.controller("HeaderCtl", ["$scope", "$location", 'growl', HeaderCtl]);
The similar working controller based on the module:
(function() {
var app = angular.module("myApp");
var loginController = function($scope, $rootScope, $http, $location, myApp, growl) {
// $scope.currenttab = $scope.isLoggedIn;
$scope.sendDt = function() {
$http.post('/login', {
username: $scope.user.username,
password: $scope.user.password,
})
.success(function(user) {
$rootScope.isLoggedIn = 'yes';
console.log('successfully logged in and redirecting to :');
$location.path("/");
$http.get('/getnavlist').success(function(list) {
if (list !== '0') { // got some menus
$rootScope.navlist = list;
$location.path("/" + list[0].value);
}
});
},
function() {
console.log('error in logging in');
$rootScope.message = 'user name or password is wrong';
$location.path("#/welcomeLogin");
});
}
};
app.controller("loginController", loginController);
}());
Finally, the error module with logic stripped out:
(function() {
var app = angular.module("myApp");
var signUpController = function($scope) {
$scope.formModel = {};
console.log("Woomp!");
}
app.controller("signUpController", signUpController);
}());

You can't inject angular module as injectable inside factory function. In loginController you had injected myApp(module name) as a dependency. This is root cause of your problem.
Change
//VVVVV//remove this
var loginController = function($scope, $rootScope, $http, $location, myApp, growl) {
to
var loginController = function($scope, $rootScope, $http, $location, growl) {
