Hi !

The workflow classes are in the autoload array.
But the method eZWorkflowType::loadAndRegisterType don't use it but use his own include file.
So we can't override a kernel workflow easily.

Best regards,
Thomas.

Steps to reproduce

Try to overwrite a kernel workflow.
For example :

• Create the file extension/my_extension/eventtypes/event/ezmultiplexer/ezmultiplexertype.php
• Allow the kernel override in config.php
• Regenerate the autoload array : bin/php/ezpgenerateautoloads.php -o
• You can see in the var/autoload/ezp_override.php file that your workflow is overwrite
  But it doesn't
