title: ExtJs 3.1.0 : the documentation (docs/index.html) does not use the same "official" ext-all.js source code
body: <p>If you download extjs-3.1.0 you'll see in the folders two versions of ext-all.js:</p>
  
  <p>The first one is at the root and is 649 777 bytes.
  The second one is in the ext-3.1.0\docs\resources folder and is 538 956 bytes.</p>
  
  <p>If you modify the <code>ext-3.1.0/docs/index.html</code> file and change this simple line:</p>
  
  <pre><code>&lt;script type="text/javascript" src="resources/ext-all.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>to the "current release" :</p>
  
  <pre><code>&lt;script type="text/javascript" src="../../ext-all.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>the index.html documentation doesn't work anymore.</p>
  
  <p>Firebug says "sp is not defined".</p>
  
  <p>If you could explain why those two ExtJs files are differents, that would help me. Actually I do think I have to rely on the root file <code>extjs-3.1.0/ext-all.js</code>, but I'd like first to make the <code>docs/index.html</code> work with it! And I can't: if I change those lines:</p>
  
  <p>from:</p>
  
  <pre><code>&lt;script type="text/javascript" src="resources/ext-all.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>to:</p>
  
  <pre><code>&lt;script type="text/javascript" src="../../ext-all.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>the help file doesn't work anymore whereas <strong>it should be able to use the "official" 3.1.0 code</strong> (from my p.o.v.)!! What am I misunderstanding?</p>
