Ah ok i see,

so i have to do something like

$repository = new Tx_Myextension_Domain_Repository_CollectionRepository();
$query = $repository->createQuey();
$query->matching(...);
$this->view->assign('collection', $query->execute());

This should work (AFAK findByFoo() returns $query->execute(), too)?

Thank you
