tinyMCE with ExtJs, not defined error

Question

I'm trying to implement a tinyMCE editor into an ExtJs environment. But it's not going well.

First things first: Include the necessary scripts.

<script src="js/jquery-1.2.1.min.js" type="text/javascript"></script>
<script src="ext-2.3.0/adapter/jquery/ext-jquery-adapter.js" type="text/javascript"></script>
<script src="ext-2.3.0/ext-all.js" type="text/javascript"></script>
<script src="js/miframe-min.js" type="text/javascript"></script>
<script src="js/Ext.ux.TinyMCE.js" type="text/javascript"></script>

(I have old versions of JQuery and Ext because I tried to copy the example/demo exactly).

Then I use some Javascript to define the window with tinyMCE in it, click on a button to initiate the popup window. When I try and see the result in firefox I get one error:

Error: tinymce is not defined
Source File: http://localhost:4927/ExtJS/js/Ext.ux.TinyMCE.js
Line: 301

Leading to this snippet:

/** ----------------------------------------------------------
 WindowManager
*/        
var WindowManager = Ext.extend( 

 function( editor ) {
  WindowManager.superclass.constructor.call( this, editor );
 },

 tinymce.WindowManager,  //THIS IS WHERE THE ERROR IS

 {
  // more code

What am I doing wrong?
This is the base code I grabbed from the official TinyMCE ext page. So the js file must be okay, indicating I made a mistake elsewhere.

Yarr. Should include the actual plugin as well.

<script src="js/tiny_mce_src.js" type="text/javascript"></script>

Done.
