User Backstack with backbone-boilerplate?

[fabnoe]

Hey,
I tried do use backstack with bbb (https://github.com/tbranyen/backbone-boilerplate) but i got lot's or conflicts when i try to import backstack with requirejs.

I tried' to rewrite the header of the plugin (as backbone.layoutmanager does)

(function(window) {
    "use strict";

    // Alias the libraries from the global object.
    var Backbone = window.Backbone;
    var _ = window._;
    var $ = window.$;

}(this, function ($, _, Backbone) {
.....

But Now I get this error:
Uncaught TypeError: Cannot read property 'StackNavigator' of undefined
