We were in the process of updating an older application to work with AMFPHP and cake1.2. We were getting some fairly serious errors on the AMFPHP connection.

We found that one part of the fix was to comment out line 177 in cake_gateway.php and add in a require_once of your app_controller.php file. (This assumes you have an application directory-level app_controller.php file.)

//loadController(null);
require_once('app_controller.php');

We were unable to get App::import(), the new method of loading items in cakePHP 1.2, to work in a similar manner as the loadController() method.
