I'm currently working on a separate script connected to my XF installation using the code from this post http://xenforo.com/community/threads/how-to-create-a-bridge.28515/#post-332370 PHP: // Include custom libraries and initialization code here // How to use XenForo Objects: Once initialized the below you can use XenForo objectsdefine('XF_ROOT', MY_SCRIPT_PATH . '/path/to/xf/root/');define('TIMENOW', time());define('SESSION_BYPASS', false); // if true: logged in user info and sessions are not neededrequire_once(XF_ROOT . '/library/XenForo/Autoloader.php');XenForo_Autoloader::getInstance()->setupAutoloader(XF_ROOT . '/library');XenForo_Application::initialize(XF_ROOT . '/library', XF_ROOT);XenForo_Application::set('page_start_time', TIMENOW);XenForo_Application::disablePhpErrorHandler();XenForo_Session::startPublicSession();error_reporting(E_ALL & ~E_NOTICE); // Turn off the strict error reporting. It runs quite well except for one particular thing: the code event listeners I set up (especially in order to extend XenForo_Model_XXXX) do not seem to fire. Instead, I get an error Code: Call to undefined method XenForo_Model_XXX::YYY() each time I try to access one of my custom functions. NB: The code events fire totally fine (i.e.: I'm able to access my member functions) when I create an instance from within XF script. The problem is only within my bridge script. I finally managed to get my own listeners working by adding them manually via this line of code, added just below the previous block: PHP: XenForo_CodeEvent::addListener('load_class_model', array('My_Listeners_Class', 'listenerCallback')); This is fine for listeners I am aware of, but it is not suitable in cases where other addons modify a function behaviour. Where should I have a look in order to fix this issue?
