Zend Autoloader unable to find existing file

Question

I'm having an unusual autoloading problem with my Zend website. Up until now autoloading has been working a treat. Now though, I added a new file the project and autoloading just can't find it. I've reduced the problem to the minimal test case and was wondering if anyone could help me out.

In my website I have a the usual directory structure, like so:

site/
  application/...
  library/
    Zend/...
    PHPUnit/...
    Ext/
      Extras/
        Test.php
      Service/
        Test.php

I've correctly set up auto loading (as per other helpful comments on StackOverflow) and registered the Ext_ namespace, which is proved by being able to correctly instantiate Ext_Extras_Test.

The problem comes when I try to instantiate Ext_Service_Test. Autoloading "failed to open stream". I've checked the correct spelling, listed the directory contents using find, ls, and the file explorer to make sure that the file exists in the correct place.

I just can't get it to &^%%£* find the file! Does anyone have any clues?

Found it you are trying to override a resource autoloader, even though it's not specified I'm pretty sure this will effect all namespaces:

42.3.2. The Module Resource Autoloader Zend Framework ships with a concrete implementation of Zend_Loader_Autoloader_Resource that contains resource type mappings that cover the default recommended directory structure for Zend Framework MVC applications. This loader, Zend_Application_Module_Autoloader, comes with the following mappings:

forms/       => Form
models/      => Model
    DbTable/ => Model_DbTable
    mappers/ => Model_Mapper
plugins/     => Plugin
services/    => Service
views/
    helpers  => View_Helper
    filters  => View_Filter

As an example, if you have a module with the prefix of "Blog_", and attempted to instantiate the class "Blog_Form_Entry", it would look in the resource directory's "forms/" subdirectory for a file named "Entry.php".

When using module bootstraps with Zend_Application, an instance of Zend_Application_Module_Autoloader will be created by default for each discrete module, allowing you to autoload module resources.
