syfmony2中的樹枝返回空白

我的問題是我的控制器成功完成，但樹枝/視圖然後呈現空白。該請求不返回HTML。syfmony2中的樹枝返回空白

我控制器結束罰款：

$logger->info('Now sending song [' . $song->getId() . ' to twig'); 
    return array('song'=>$song); 
}

因爲我沒有錯誤，這是很難找到的問題。我只有從獨白的dev.log：

[2011-10-04 07:41:03] app.INFO: Now sending song [672] to twig [] [] 
[2011-10-04 07:41:03] event.DEBUG: Notified event "kernel.view" to listener "Sensio\Bundle\FrameworkExtraBundle\EventListener\TemplateListener::onKernelView". [] [] 
[2011-10-04 07:41:03] event.DEBUG: Listener "Sensio\Bundle\FrameworkExtraBundle\EventListener\TemplateListener::onKernelView" stopped propagation of the event "kernel.view". [] []

[2011-10-04 07:41:03] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Bundle\WebProfilerBundle\EventListener\WebDebugToolbarListener::onKernelResponse". [] []

我認爲，第3行必須是問題，但我沒有一個線索是什麼意思，或者決議的任何手段。

編輯：如果我改變我的控制器： - 刪除@Template（） - 底好像是：

$logger->info('Now sending song [' . $song->getId() . '] to twig'); 
$content = $this->renderView('MyPadBundle:Play:index.html.twig', array('song'=>$song)); 
$logger->info('content rendered'); 
return new Response($content);

然後我dev.log是：

[2011-10-04 09:42:52] app.INFO: Now sending song [189] to twig [] [] 
[2011-10-04 09:42:53] app.INFO: content rendered [] [] 
[2011-10-04 09:42:53] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Component\HttpKernel\EventListener\ResponseListener::onKernelResponse". [] [] 
[2011-10-04 09:42:53] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Bundle\SecurityBundle\EventListener\ResponseListener::onKernelResponse". [] [] 
[2011-10-04 09:42:53] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Bridge\Monolog\Handler\FirePHPHandler::onKernelResponse". [] [] 
[2011-10-04 09:42:53] event.DEBUG: Notified event "kernel.response" to listener "Sensio\Bundle\FrameworkExtraBundle\EventListener\CacheListener::onKernelResponse". [] [] 
[2011-10-04 09:42:53] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Component\HttpKernel\EventListener\ProfilerListener::onKernelResponse". [] [] 
[2011-10-04 09:42:53] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Bundle\WebProfilerBundle\EventListener\WebDebugToolbarListener::onKernelResponse". [] []

這就像內核不能返回響應？

我不知道什麼是錯的，但是這並解決它：

$logger->info('Now sending song [' . $song->getId() . '] to twig'); 
$em->clear(); 
return array('song'=>$song);

應該早就知道這將是教義與缺少的錯誤報告。無論如何，表是隻有1000行，所以不知道它如何可以太多的樹枝太過處理，特別是因爲我只通過一行/實體。

不得不承認我對教義感到失望;或者問題在於symfony的模板設計不好？
