php - Doctrine2 bidirectional manyToMany - Undefined index -

adding new favourite dish user (this works):

$user = $em->getrepository('user')->find($userid); $dish = $em->getrepository('dish')->find($dishid); $user->addfavouritedish($dish); $em->persist($user); $em->flush();

getting users has dish favourite (this doesn't work)

$dish = $em->getrepository('dish')->find($dishid); echo 'there '.count($dish->getfavouriteusers()).' users has dish favourite';

error above:

string(23) "undefined index: dish" string(88) "/srv/www/project/vendor/doctrine/orm/lib/doctrine/orm/persisters/basicentitypersister.php"

join table:

dinner.user_dish id, user_id, dish_id

the manytomany in dish entity says mappedby: dish. however, in fact mapped favouritedishes. alter favouritedishes:
