Hi Maverick, there's an error on the track link that appear in the activity stream, the $track->id is 0 always but in the tracks table the ID that appears is OK (not 0).

This is my code, is ok I think, just copy paste.

                $link = JRoute::_('index.php?option=com_gpstools&view=gpstools&task=viewtrack&id='.$track->id . ":" . $track->alias.$this->getItemId());

                $act = new stdClass();

                $act->cmd       = 'wall.write';

                $act->actor 	= $user->id;

                $act->target 	= 0; // no target

                $act->content 	= '';

                $act->app       = 'wall';

                $act->cid       = 0;

            		$act->title 	= JText::_('{actor} ha subido una nueva ruta: <a style="color:#43a1b9 !important;" href="'.$link.'">'.$track->title.' <img src="http://www.teamrunning.es/images/ruta.png" style="vertical-align:middle;width:16px;height:16px;"></a>' );

            		$act->content 	= $track->description;

                CFactory::load('libraries', 'activities');

                CActivityStream::add($act);

Thanks in advanced Maverick.
