[TYPO3-dev] New Extension does not show anything

[Dirk Ho]

Hi all,

I tried to create a new extension with the Extension Builder extension.

Aggregate Root is a Model called "Category", having a n:1 relation to 
"Forum" ("Forum has a n:1 relation to "Topic", "Topic" has a n:1 
relation to "Post").

I added the extension "Forumlisting" to a page named "Forum". When I now 
call "Forum" nothing is shown (except the page's template). I already 
cleared Cache,... but it didn't work.

Any idea, what I do wrong? When i put file_put_contents to 
CategoryController's list method this file is not written. 
/var/log/apache2/error.log does not show any error.

Beneath I posted some code/config information. Do you need additional 
information?

Thanks and best wishes,

Dirk

My ext_localconf.php looks like that:
<?php
if (!defined('TYPO3_MODE')) {
         die('Access denied.');
}

\TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
         'DH.' . $_EXTKEY,
         'Forumlisting',
         array(
                 'Category' => 'list',

         ),
         // non-cacheable actions
         array(
                 'Category' => 'list',

         )
);

My Category Controller looks like:

<?php
namespace DH\Forum\Controller;
/**
  * CategoryController
  */
class CategoryController extends 
\TYPO3\CMS\Extbase\Mvc\Controller\ActionContro$

         /**
          * categoryRepository
          *
          * @var \DH\Forum\Domain\Repository\CategoryRepository
          * @inject
          */

		/**
		 * @var \TYPO3\CMS\Extbase\Persistence\Generic\PersistenceManager
		 * @inject
		 */
		protected $persistenceManager;


         /**
          * action list
          *
          * @return void
          */
         public function listAction() {
 
file_put_contents('/var/www/supporters-karlsruhe.de/log.log', 'TEST');

			for ($i = 0; $i <= 3; $i++) {
			  $category = 
$this->objectManager->get('\\DH\\Forum\\Domain\\Model\\Category');
			  $category->setTitle('A'.$i);
			  $category->setDescription('A');
			  $category->setOrderId($i);
			  $category->setCreatedAt(now());
			}

			$this->persistenceManager->persistAll();

			$categories = $this->categoryRepository->findAll();
			$this->view->assign('categories', $categories);
         }
}


My Resources\Private\Template\Category\List.html looks like
<ul class="category-list">
   <f:for each="{categories}" as="category}>
     <li>{category.title}</li>
   </f:for>
</ul>
