Symfony2项目-app_dev.php有效，但app.php只在特定页面上有重定向循环

我不完全确定发生了什么，因为这是我第一次遇到这种问题，但出于某种原因，我的Symfony2项目中的一个特定页面在app.php上有一个重定向循环，但在app_dev.php上时，这很好。

该页面被称为/files，该页面的路由如下：

app_files_table:
    path: /files
    defaults: { _controller: AppBundle:File:list }

这个页面的控制器方法非常简单：

public function listAction()
{
    $em = $this->getDoctrine()->getManager();
    $documents_repo = $em->getRepository('AppBundle:Documents');
    $documents = $documents_repo->findAll();
    return $this->render('AppBundle:tables:files.html.twig', array(
        'files' => $documents
    ));
}

trick模板只是一个标准布局，它将我的所有其他页面(扩展我的基本文件，即标题(与主体中的以下代码相匹配：

{% if files is not empty %}
{% for file in files %}
    <tr>
        <th scope="row">{{ file.id }}</th>
        <td>{{ file.name }}</td>
        <td>{{ file.displayName }}</td>
        <td>{{ file.product.model }}</td>
        <td class="text-center">
            <a class="btn btn-primary" href="{{ file_path }}/{{- file.name -}}" target="_blank" download><i class="fa fa-download"> </i></a>
            <a class="btn btn-danger file-delete" data-confirm-title="Are you sure?" data-confirm-message="You will not be able to undo this action." href="javascript:deleteFile({{ file.id }});" id="delete_file_{{ file.id }}" data-toggle="tooltip" title="Remove File"><i class="fa fa-remove"> </i></a>
        </td>
    </tr>
{% endfor %}
{% else %}
<tr>
<td colspan="5">There are no files in the database</td>
</tr>
{% endif %}

我没有编辑app.php、app_dev.php和.htaccess文件，它们和安装框架时一样。我还清除了两次缓存，包括手动删除所有缓存文件，但重定向问题仍然存在。

这是其他人遇到并设法解决的问题吗？因为我很困惑为什么它会发生在这个页面上——事实上，我甚至试图在模板呈现之前在控制器中放入一个die((语句，但同样的事情也发生了，所以它一定与路由有关？

感谢您的帮助。

谢谢
