注釈付きのコントローラーを定義しました
@Route("/add,{elId},{elType},{parentId}",name="MeaTask_Add", defaults={"elId"=null,"elType"=null, "parentId"=null})
public function addAction($elId=null, $elType=null, $parentId=null, Request $request){
ここのように使ってみます
$this->generateUrl('MeaTask_Add',array(
'parentId'=>$parentId
))
そして得る
