title: Routing exception in symfony ("The "/league/:id_league/members/new" route has some missing mandatory parameters (:id_league)")
body: <p>Hi everyone and sorry for my bad english,</p>
  
  <p>I have a problem with the routing: in the members page to a league ("/league/ID_LEAGUE/members"), the link for the action "new" becomes "/league/members/news" (the league's id disappears).
  I would like to keep that ID and create a url like "/league/ID_LEAGUE/members/ new" so you can select in selectbox the current league...</p>
  
  <p>I'm trying to do this as follows</p>
  
  <pre>
  members:
      class: sfDoctrineRouteCollection
      options: { model: Members, module: members, column: id_member, with_wildcard_routes: true }
  
  # List to league (id)'s members
  memebers_league:
      url: /league/:id/members
      options: { model: Members, type: list }
      param: { module: members, action: index }
  
  # New member
  members_new:
      url: /league/:id_league/members/new
      class: sfDoctrineRoute
      options: { model: Members, type: object }
      param:   { module: members, action: new }
  </pre>
  
  <p>With these routes I get this exception "The "/league/:id_league/members/new" route has some missing mandatory parameters (:id_league)" (in "Members.class.php" there is the getter "getIdLeague() ).</p>
  
  <p>someone could help me?</p>
  
  <p>thanks in advance</p>
