I added a custom field to my profile, which is being used in event registration.  I am using CiviCRM 2.2/Drupal 6.10.
I get the following error:
Fatal error: require_once() [function.require]: Failed opening required 'CRM/Core/Page/AJAX.php' (include_path='.:/home/zvmlyg/public_html/sites/all/modules/civicrm:/home/zvmlyg/public_html/sites/all/modules/civicrm/packages:.:/usr/lib/php:/usr/local/lib/php') in /home/zvmlyg/public_html/sites/all/modules/civicrm/CRM/Core/Invoke.php on line 183

The lines are:
else {
                $newArgs  = explode( '/',
                                     $_GET[$config->userFrameworkURLVar] );
                require_once( str_replace( '_',
                                           DIRECTORY_SEPARATOR,
                                           $item['page_callback'] ) . '.php' );

The page_callback is:
CRM_Event_Controller_Registration.php
In fact this file does not appear in the distribution.  Could this be a serious bug?
Thanks

If what you're saying is that the file below is not present in your installation ... then it's possible that something went wrong in the upgrade and some 2.2 files that should have been copied / untarred did not make it:

home/zvmlyg/public_html/sites/all/modules/civicrm/CRM/Event/Controller/Registration.php

You might want to repeat untar / copying of the 2.2 distribution files.
