<HTML><BODY><p>I have read the <a rel="nofollow" href="http://www.istos.it/blog/drupal/drupal-entities-part-1-moving-beyond-nodes" _mce_href="http://www.istos.it/blog/drupal/drupal-entities-part-1-moving-beyond-nodes">tutorial</a>, and the API, looked through the code <a rel="nofollow" href="http://drupal.org/project/examples" _mce_href="http://drupal.org/project/examples">examples</a>. <br>But when it came down to implementation it didn't work as i thought it would. <br>Please help. I am trying to avoid using the Views module for now, just for learning purposes.</p>

<p>The problem is that entity_view(..) returns nothing, and og_load_multiple(..) returns array of entities but there is no content and no fields.</p>
<p>If this worked, i would probably override the controller, with clans_pages_entity_info_alter(..), and added a new view mode 'list'.</p>
<p>Can someone please share a working code for displaying a list of entities with a pager? Thanks.</p>
<p>P.S. I took the groups for example but i dont mind any other type of entities.</p><span></span><br><br><br>--<br>Современная мобильная почта - для смартфонов и телефонов.<br>Оцените мобильный m.mail.ru с Вашего телефона</BODY></HTML>
