klasa kontrolera

$user = $this->getUser();

foreach($user->getTiles() as $tile) {
echo $tile->getName();
$user->removeTile($tile);
}
$em->persist($user);
$em->flush();

czemu nie działa usuwanie obiektów z encji Tile?

@qwelukasz: Tam gdzie masz deklarację removeTitle dodaj $title->setUser(null)

[qwelukasz]

@slave89: w Tile mam tylko AddUser/removeUser albo getUser - to jest many to many.

wielu userow moze miec wiele tile
i wiele tile moze miec wiele userow

ex.
user 1: tile[1,1,3,4]
user 2: tile[1,3,4,1,5] itd..
