Uncaught TypeError: undefined is not a function / Ext.Require / ExtJS

Question

I'm using ExtJS and GeoExt inside a Symfony application. After some troubles caused by wrong routing due to the assets dumping of Symfony, everything is working fine at the moment.

After finding a problem when trying to display layers of OpenLayers inside an Ext Panel, I tried to solved it this way :

Ext.require([
  'GeoExt.panel.Map',
  'GeoExt.tree.OverlayLayerContainer',
  'GeoExt.tree.BaseLayerContainer',
  'GeoExt.data.LayerTreeModel',
  'GeoExt.tree.View',
  'GeoExt.tree.Column',
]);

Problem, I got this error:

 Uncaught TypeError: undefined is not a function 

The error is coming from the Ext.Require
If I just put

Ext.require([
]);

with nothing inside, no error. As soon as I put something inside, even if it's a Ext.something, the error shows up again.

The error is coming from :

/server path/ExtJS4.2/src/menu/Manager.js:182

Why ?

Answer 1

Found the reason, I was using

ext-debug.js

Switched to

 ext-all.js

and the error is gone.
My function are still not working tho, but it wasn't the theme of my question.
