I'm trying to get a many-to-many relationship between Users and Settings. The models seem to be generated correctly, however the following query fails:

"User_Setting" with an alias of "us" in your query does not reference the parent component it is related to.

 $q = new Doctrine_RawSql();
 $q->select('{s.*}, {us.*}')
     ->from('User u 
             CROSS JOIN Setting s
             LEFT JOIN User_Setting us
             ON us.usr_auto_key = u.usr_auto_key 
             AND us.set_auto_key = s.set_auto_key')
     ->addComponent('s', 'Setting s INDEXBY s.set_auto_key')
     ->addComponent('us', 'User_Setting us')
     ->where(u.usr_auto_key = ?',$this->usr_auto_key);

 $this->settings = $q->execute();    

Does anyone spot a problem?

This is my YAML:
