Just by accident i found this in CLogRouter when i studied the framework code:
public function setRoutes($config) { $routes=$this->getRoutes(); foreach($config as $c) { if(isset($c['class'])) $this->_routeConfig[]=new CConfiguration($c); else throw new CException(Yii::t('yii','Log route configuration must have a "class" value.')); } }
$routes is never used?!
