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 have encountered the same problem and in my case it was happening as a result of this problem:

I had the controllers defined in a separate module (called 'myApp.controllers') and injected to the main app module (called 'myApp') like this:

angular.module('myApp', ['myApp.controllers'])

A colleague pushed another controller module in a separate file but with the exact same name as mine (i.e. 'myApp.controllers' ) which caused this error. I think because Angular got confused between those controller modules. However the error message was not very helpful in discovering what is going wrong.
