Wrong tutorial, missing an argument in a function...

[totty90]

At http://backbonetutorials.com/organizing-backbone-using-modules/

define([ 'jquery', 'underscore', 'backbone', 'views/projects/list', 'views/users/list' ], function($, _, Backbone, Session, ProjectListView, UserListView){

Is wrong because the Session is not loaded.

Also in the same page: http://backbonetutorials.com/organizing-backbone-using-modules/

app_router.on('showProjects', function(){

should be

app_router.on('route:showProjects', function(){

Ok yes, good catch. Thomas just needs to fix the tutorial to match the source - just remove Session and add the route as you described.

It's actually correct in the github source ;-D

Actually... would you mind updating the code yourself? Then make a pull request and you'll get a nice contribution credit.
