Symfony2中 - 在字段形式的問題與映射對象

Question

Objective具有一個Perspective

class Objective{ 
    ... 
    public function setPerspective(\Cboujon\BSCBundle\Entity\Pespective $perspective = null) 
    { 
     $this->perspective = $perspective; 

     return $this; 
    } 
} 

Objective.orm.yml

Cboujon\BSCBundle\Entity\Objective: 
manyToOne: 
     perspective: 
      targetEntity: Perspective 
      inversedBy: objectives 
      joinColumn: 
       name: perspective_id 
       referencesColumn: id 

ObjectiveType.php

public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder->add('perspective'); 
    } 

Symfony2呈現與所有觀點的組合框的窗體。那沒問題！ butn當我提交create form我得到的錯誤：

ContextErrorException: Catchable Fatal Error: Argument 1 passed to Cboujon\BSCBundle\Entity\Objective::setPerspective() must be an instance of Cboujon\BSCBundle\Entity\Pespective, instance of Cboujon\BSCBundle\Entity\Perspective given, called in /home/cristhian/php_apps/Symfony/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 376 and defined in /home/cristhian/php_apps/Symfony/src/Cboujon/BSCBundle/Entity/Objective.php line 63

注：我也嘗試：

 $builder->add('perspective', 'entity', array(
       'class' => 'CboujonBSCBundle:Perspective', 
       ) 
      ) 
    ; 

，但我得到了同樣的錯誤。注2：如果我從setPerspective定義中刪除\Cboujon\BSCBundle\Entity\Pespective，我可以提交表單OK。

我在做什麼錯？

iThere是在實體二傳手一個錯字指定參數類型時：

public function setPerspective(\Cboujon\BSCBundle\Entity\Pespective $perspective = null) 
{ 
    $this->perspective = $perspective; 

    return $this; 
} 

不是\ Cboujon \ BSCBundle \實體\ 兩英，但\ Cboujon \ BSCBundle \實體\ 視角
