I am trying to build the compatibility of one CiviCRM 4.4 extension for version 4.5.
Some of the PHP files which successfully override the Core PHP files in 4.4 don't work properly in 4.5.
Please advice if there is any structure change which can cause this.

Details:
Registration.php under CRM/Event/Form/ cannot override;
Register.php under CRM/Event/Form/Registration can override, but when I submit this page an "reclare class" error popup (see attachments), rename either core Register.php or extension Register.php works.

Please find the tree structure of the extension in attachments.

Perhaps this explains what you're seeing - http://forum.civicrm.org/index.php/topic,33702.0.html

Thanks, I think this might be the bit which cause the problem.
Look forward to see the solution or information released in the near future.
