ExtJs 3.1.0 : the documentation (docs/index.html) does not use the same "official" ext-all.js source code

If you download extjs-3.1.0 you'll see in the folders two versions of ext-all.js:

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.

If you modify the ext-3.1.0/docs/index.html file and change this simple line:

<script type="text/javascript" src="resources/ext-all.js"></script>

to the "current release" :

<script type="text/javascript" src="../../ext-all.js"></script>

the index.html documentation doesn't work anymore.

Firebug says "sp is not defined".

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 extjs-3.1.0/ext-all.js, but I'd like first to make the docs/index.html work with it! And I can't: if I change those lines:

from:

<script type="text/javascript" src="resources/ext-all.js"></script>

to:

<script type="text/javascript" src="../../ext-all.js"></script>

the hel开发者_如何学编程p file doesn't work anymore whereas it should be able to use the "official" 3.1.0 code (from my p.o.v.)!! What am I misunderstanding?

Sorry I was wrong this was a beginner's mistake... I'm ashamed to say that but...

This should've been:

<script type="text/javascript" src="../ext-all.js"></script>

instead of:

<script type="text/javascript" src="../../ext-all.js"></script>
