Problem with front-end and back-end

Hello!

Trying to cook this lesson about organazing directories for applications with front-end and back-end using WebApplicationEnd behavior.
Tried to access into website root, but there is an error appeared :

endName; public function getEndName() { return $this->_endName; } // Run application's end. public function runEnd($name) { $this->_endName = $name; // Attach the changeModulePaths event handler // and raise it. $this->onModuleCreate = array($this, 'changeModulePaths'); $this->onModuleCreate(new CEvent($this->owner)); $this->owner->run(); // Run application. } // This event should be raised when CWebApplication // or CWebModule instances are being initialized. public function onModuleCreate($event) { $this->raiseEvent('onModuleCreate', $event); } // onModuleCreate event handler. // A sender must have controllerPath and viewPath properties. protected function changeModulePaths($event) { $event->sender->controllerPath .= DIRECTORY_SEPARATOR.$this->_endName; $event->sender->viewPath .= DIRECTORY_SEPARATOR.$this->_endName; } }endName; public function getEndName() { return $this->_endName; } // Run application's end. public function runEnd($name) { $this->_endName = $name; // Attach the changeModulePaths event handler // and raise it. $this->onModuleCreate = array($this, 'changeModulePaths'); $this->onModuleCreate(new CEvent($this->owner)); $this->owner->run(); // Run application. } // This event should be raised when CWebApplication // or CWebModule instances are being initialized. public function onModuleCreate($event) { $this->raiseEvent('onModuleCreate', $event); } // onModuleCreate event handler. // A sender must have controllerPath and viewPath properties. protected function changeModulePaths($event) { $event->sender->controllerPath .= DIRECTORY_SEPARATOR.$this->_endName; $event->sender->viewPath .= DIRECTORY_SEPARATOR.$this->_endName; } }

WebApplicationEndBehavior.php is in protected/components folder.
What could be the problem?
Thanks.
