Hi. You can override some kernel classes with the kernel override feature, but as said in some threads like http://share.ez.no/forums/developer/override-kernel-classes, the use of include calls can make this feature don't work as expected.

This is one of the cases. A quick fix is comment or delete this line
https://github.com/ezsystems/ezpublish/blob/master/lib/ezutils/classes/ezmoduleoperationinfo.php#L755
i've tested and work as i would expect.

But i think we can also changes lines like

'default_call_method' => array( 'include_file' => 'kernel/shop/ezshopoperationcollection.php',
                                                                       'class' => 'eZShopOperationCollection' ),

to avoid the include_file definition, and probably get ride of it in the ezmoduleoperationinfo.php (i mean, delete it from function parameters and so on)

Steps to reproduce

• Be sure you have

  define( 'EZP_AUTOLOAD_ALLOW_KERNEL_OVERRIDE', true );
  

• Enable content_read operation in workflow.ini override
• copy kernel/content/ezcontentoperationcollection.php to extension/[yourextension]/classes/
• Modify readObject funciton in the copied class. add there something dummy, for example

   eZLog::write( "Starting to read" );
  

• regenerate your autoloads with php/bin/ezpgenerateautloads.php -e -k -o
• Try to load any content on your install, for example, your home page.

Expected result: you should see somethin in var/log/common.log
but you won't see nothing...
