My apologies. I've not seen something I should have earlier. Also the
instance that is behind all of this is and instance of
ActiveRecordFormClass.
So, in PHP4, the correct overridden method is called:
ActiveRecordFormClass::_dispatchSave().
In PHP5, the FormClass::_dispatchSave() is called...???
BTW I'm tracing this though with xdebug.
Regards,
Tom

It's funny how talking or writing about something uncovers things you
didn't see before.
In an effort to tidy up the code I heeded the original implementors
comments and made the methods private (they were previously undeclared).
Making them public seems to have fixed the problem.

Hello,
I'm curious, what are the most popular methods to perform session
replication across http servers in PHP?
I've read about repcache(memcached module) and Mysql.
anything else? is there some mod_php_session_replication httpd module?
thanks

I personally just use MySQL and the session_set_save_handler() stuff
attached to a class. Many of the frameworks, such as Zend, also support
Database Sessions.
