[TYPO3-project-seminars] Hook modifySingleView

[Ben Kerner]

Hi Group,

i try to add a additional field to the single view with the hook 
modifySingleView.

But i get no output.

My ext_localconf.php of the seminars-ext (db_sem_be_meth is my extension):

// includes my hook class
require_once(t3lib_extMgm::extPath('db_sem_be_meth') . 
'class.tx_ext_hook.php');
// register my hook objects
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['seminars/pi1/class.tx_seminars_pi1.php']['hooks'][] 
= 'EXT:db_sem_be_meth/class.tx_ext_hook.php:tx_ext_hook';


my class.tx_ext_hook.php:

<?php
 class tx_ext_hook {
  function modifySingleView($obj){
   $content = "try1";
   return $content;
  }
 }

 ?>


Or isn a output here impossible?

Greetings
Ben
