Symfony2 - 为服务指定的类型名称不匹配

我尝试使用自己的ImageType配置EasyAdminBundle以在我的ArticleType中上传文件.所以我创建了这个服务app\config\services.yml:

services:
    oah_news_form_type_image: 
        class: OAH\NewsBundle\Form\ImageType
        tags: [ { name: form.type, alias: 'oah_news_form_type_image' } ]

并试图在我的电话中调用它app\config\config.yml:

easy_admin:
entities:
        Article:
            class: OAH\NewsBundle\Entity\Article
            form:
                fields:
                    - Titre
                    - Auteur
                    - Date
                    - Categorie
                    - { property : 'Image', type : oah_news_form_type_image}

但我有以下错误,我不知道如何解决它:

The type name specified for the service "oah_news_form_type_image" does not match the actual name. Expected "oah_news_form_type_image", given "oah_newsbundle_image"

我的ImageType:

class ImageType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('file', 'file');
    }

    /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'OAH\NewsBundle\Entity\Image'
        ));
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'oah_newsbundle_image';
    }
}

谢谢 !

看来你的别名,你必须匹配return的getName().
