Error: Argument is not a function, got undefined

Question

Using AngularJS with Scala Play, I\'m getting this error.

Error: Argument \'MainCtrl\' is not a function, got undefined

I\'m try

Answer 1

I had the same error message (in my case : "Argument 'languageSelectorCtrl' is not a function, got undefined").

After some tedious comparison with Angular seed's code, I found out that I had previously removed a reference to the controllers module in app.js. (spot it at https://github.com/angular/angular-seed/blob/master/app/js/app.js)

So I had this:

angular.module('MyApp', ['MyApp.filters', 'MyApp.services', 'MyApp.directives'])

This failed.

And when I added the missing reference:

angular.module('MyApp', ['MyApp.filters', 'MyApp.services', 'MyApp.controllers', 'MyApp.directives'])

The error message disappeared and Angular could instanciate the controllers again.
