[semiaLi]

Hello, I am blocked i need your help,
I want to see the Global Timeline and the timeline of the group in which i am member. I don't want to use the method which make me creating timeline for each member of the group.

//this list return me the groups in which i am member
$listGroups = $this -> getDoctrine() ->getRepository('TimeLineBundle:Space')->findSpacesId($user->getId());
foreach($listGroups as $space){
$listId[] = $space->getId();
}
$criterias = $qb->logicalOr(
$qb->field('context')->equals('GLOBAL'),
$qb->logicalAnd(
$qb->field('model')->equals($space),
$qb->field('identifier')->in($listId)
)
);
$qb->setPage($page);
$qb->setMaxPerPage(15);
$qb->setCriterias($criterias);
$timeline = $qb->execute(array('paginate' => true, 'filter' => true));

==> i have in my list only the global one :( and to test i tried to recuperate only the posts of group but it return empty list
