regex - avoiding interference between slugs and controller or plugin names in cakephp 2.x router -

i'm looking way avoid interference between slugs , controller/plugin in cakephp url automatically. according article (http://lecterror.com/articles/view/advanced-routing-with-cakephp-one-example) route.php file likes this:

$exceptions = cache::read('exception_url_list');   if ($exceptions===false) {     $controllers=app::objects('controller') ;     $plugins=app::objects('plugin');     $i=0 ;     foreach ($controllers $controller) {         $list[$i]=str_replace('controller','',$controller) ;         $i++ ;     }     $exceptions=array_merge($list,$plugins) ;     $i=0 ;     foreach ($exceptions $value) {         $value = inflector::underscore($value);         $value = strtolower($value) ;         $list[$i]=$value ;         $i++ ;     }     $exceptions=implode('|', $list) ;     cache::write('exception_url_list',$exceptions) ; }  router::connect('/:language/:typeslug',     array('controller' => 'nodetypes', 'action' => 'view'),     array(         'language'=>'[a-z]{3}',         'typeslug' => '(?!('.$exceptions.')((\w+)|$))[a-za-z\-_]+/?$',         'pass'=>array('typeslug')         )     );  router::connect('/:language/:typeslug/:nodeslug',     array('controller' => 'nodes', 'action' => 'view'),     array(         'language'=>'[a-z]{3}',         'typeslug' => '(?!('.$exceptions.')((\w+)|$))[a-za-z\-_]+/?$',         'pass'=>array('typeslug','nodeslug')         )     ); 

first route works great second route not cake search controller name same language prefix!

removing typeslug regex in second route solution.
