在Symfony 2.1中渲染树枝模板

Question

I am migrating my app to Symfony 2.1 but I'm facing a big error. I've got a command which calls the templating service to render a twig template. The code +- is:

 $content = $this->getContainer()->get('templating')->render('XBundle:Pdf:x.pdf.twig', array(
            'variablea' => '',
            'variableb' => ''
 ));

It was working without any problem in Symfony 2.0.X. But after migrating into Symfony 2.1, when that piece of code is called, an exception occurs:

Fatal error: Call to undefined method Symfony\\Bundle\\FrameworkBundle\\Templating\\Loader\\TemplateLocator::isFresh() in /vendor/symfony/assetic-bundle/Symfony/Bundle/AsseticBundle/Factory/Resource/FileResource.php on line 49

I've reported that in symfony/asseticbundle tracker on github like 14 days ago and nobody answers, which makes me think that I am the problem here... ( https://github.com/symfony/AsseticBundle/issues/122 )

What am I doing wrong?

Thanks!!

您是否清除了缓存（ php app/console cache:clear ）并重建了引导文件？

Here are a few suggestions:

• Check if you are using proper versions of the Symfony bundles. Compare the bundles versions in your composer.json file with versions in the default Symfony 2.1 distribution: https://github.com/symfony/symfony-standard/blob/v2.1.2/composer.json

• Make sure your Symfony 2.1 installation is not still using Symfony 2.0 cache files. If you are not sure about this delete the cache folder content. In your project root directory do rm -rf app/cache/* and set up appropiate permissions as explained in the documentation: http://symfony.com/doc/current/book/installation.html#configuration-and-setup
