title: There is no extension able to load the configuration for "my_bundle_name"
body: <p>I know this post is popular in here, there are a lot of questions about this problem, but nothing helped me to solve my problem. I have to ask this.</p>
  
  <p>I created a bundle named "ATL15/GoogleAnalyticsBundle".</p>
  
  <p>I want to get users parameters from app/config.yml; This is my configuration parameters, i'm loading parameters from app/parameters.yml.</p>
  
  <pre><code>atl15_google_analytics:
      client_id:  "%ga_client_id%"
      client_secret: "%ga_client_secret%"
      developer_key: "%ga_developer_key%"
      redirect_uri: "%ga_redirect_uri%"
  </code></pre>
  
  <p>I did everything i read from symfony documentation book and the web. Nothing helped me at all...</p>
  
  <p>This is my <code>DependencyInjection/Configuration.php</code> file:</p>
  
  <pre><code>&lt;?php
  
  namespace ATL15\GoogleAnalyticsBundle\DependencyInjection;
  
  use Symfony\Component\Config\Definition\Builder\TreeBuilder,
      Symfony\Component\Config\Definition\ConfigurationInterface;
  
  class Configuration implements ConfigurationInterface
  {
      public function getConfigTreeBuilder()
      {
          $treeBuilder = new TreeBuilder();
          $rootNode = $treeBuilder-&gt;root('atl15_google_analytics');
  
          $rootNode-&gt;children()
                      -&gt;scalarNode('client_id')-&gt;isRequired()-&gt;cannotBeEmpty()-&gt;end()
                      -&gt;scalarNode('client_secret')-&gt;isRequired()-&gt;cannotBeEmpty()-&gt;end()
                      -&gt;scalarNode('developer_key')-&gt;isRequired()-&gt;cannotBeEmpty()-&gt;end()
                      -&gt;scalarNode('redirect_uri')-&gt;isRequired()-&gt;cannotBeEmpty()-&gt;end()
                   -&gt;end();
  
          //var_dump($rootNode); die;
  
          return $treeBuilder;
      }
  }
  </code></pre>
  
  <p>And this is my <code>DependencyInjection/ATL15GoogleAnalyticsBundleExtension.php</code> file:</p>
  
  <pre><code>&lt;?php
  
  namespace ATL15\GoogleAnalyticsBundle\DependencyInjection;
  
  use Symfony\Component\DependencyInjection\ContainerBuilder;
  use Symfony\Component\Config\FileLocator;
  use Symfony\Component\HttpKernel\DependencyInjection\Extension,
      Symfony\Component\DependencyInjection\Loader;
  
  class ATL15GoogleAnalyticsExtension extends Extension
  {
      public function load(array $configs, ContainerBuilder $container)
      {
          $configuration = new Configuration();
          $config = $this-&gt;processConfiguration($configuration, $configs);
  
          $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
  
          foreach (array('config') as $basename) {
              $loader-&gt;load(sprintf('%s.yml', $basename));
          }
  
          foreach (array('client_id', 'client_secret', 'developer_key', 'redirect_uri') as $attribute) {
              $container-&gt;setParameter($attribute, $config[$attribute]);
          }
      }
  
      public function getAlias()
      {
          return 'atl15_google_analytics';
      }
  }
  </code></pre>
  
  <p>And yes, i loaded this bundle from <code>app/AppKernel.php</code>;</p>
  
  <pre><code>    new ATL15\GoogleAnalyticsBundle\ATL15GoogleAnalyticsBundle(),
  </code></pre>
