Question

我刚从Symfony 2.1升级到2.2。我按照这里给出的说明进行了操作：

http://symfony.com/blog/symfony-2-2-0
https://github.com/symfony/symfony/blob/2.2/UPGRADE-2.2.md

之前我的所有代码都运行得很漂亮，但现在有一些问题，在我尝试在我的应用程序中执行某些操作后，框架会在URL中注入“_fragment”。这会改变我的网址：

http://server/app_dev.php/en-GB/

为：

http://server/app_dev.php/_fragment/

然后通过twig将其作为语言环境拾取并使其失败并显示以下错误：

An exception has been thrown during the rendering of a template
("Circular reference detected when adding a fallback catalogue for locale "".")
in "/var/....../HomeBundle/Resources/views/Home/index.html.twig".

2/2 Twig_Error_Runtime: An exception has been thrown during the rendering of a template 
("Circular reference detected when adding a fallback catalogue for locale "".") 
in "/var/...../HomeBundle/Resources/views/Home/index.html.twig"
1/2 LogicException: Circular reference detected when adding a fallback catalogue for locale "".

部分回溯说：

DEBUG - Notified event "kernel.exception" to listener "Symfony\Component\HttpKernel\EventListener\ProfilerListener::onKernelException". 
DEBUG - Notified event "kernel.exception" to listener "Symfony\Component\HttpKernel\EventListener\ExceptionListener::onKernelException". 
CRITICAL - Uncaught PHP Exception Twig_Error_Runtime: "An exception has been thrown during the rendering of a template ("Circular reference detected when adding a fallback catalogue for locale "".") in "/var/...../HomeBundle/Resources/views/Home/index.html.twig"." at /var/...../app/cache/dev/classes.php line 6030 
DEBUG - Notified event "kernel.request" to listener "Symfony\Component\HttpKernel\EventListener\ProfilerListener::onKernelRequest". 
DEBUG - Notified event "kernel.request" to listener "Symfony\Bundle\FrameworkBundle\EventListener\SessionListener::onKernelRequest".

当我第一次登录应用程序时，它似乎都运行正常，请求列出应该是的语言环境：

_locale     "en-GB"
_route      "_home_index"
_route_params   "Array(_locale => en-GB)"

但是，如果我再单击另一个链接（包括返回同一页面），则会因上述错误而失败并将请求更改为：

_locale     "_fragment"
_route      "_home_index"
_route_params   "Array(_locale => _fragment)"

我的路由（对于上面的示例）如下所示：

Home_Home:
    resource:   "@HomeBundle/Controller/HomeController.php"
    type:       annotation
    prefix:     /{_locale}
    defaults:   { _locale: en }

我的配置：

framework:
    translator:      { fallback: en }
    default_locale:  en

我不认为问题是语言环境处理，而是使用添加到Symfony 2.2的新片段子处理框架。可能是以某种方式调用/激活它？（或者我缺少某种配置）。

我想我至少发现了这个问题，只需在config.yml中添加一个片段配置项就可以解决这个问题：

framework:
    fragments:       { path: /_fragment }

将Symfony 2.1升级到2.2：碎片子框架和区域设置处理中断
