When creating a jsb file:
sencha create jsb -a http://localhost/dev/index.php -p app.jsb3
Of an MVC application with in index.php:
<script type="text/javascript" src="ext-4.0.2a/ext.js"></script>
<script type="text/javascript" src="app.js"></script>
The generated app.jsb contains the Ext library js files, but not my app files except from app.js

When looking in firebug I see the Ext files loaded through XHR requests while my app files are loaded through "DOM inserts". Checking Ext.Loader.history gives all my app files.

Anybody knows what I'm doing wrong?
