Answer 1

tried to use the query_builder option from the entity formtype. But as i can't get the current user object, i don't know which category he has selected. Same problem with the EntityRepository.

As long the Category has a relation to the user, you should be able to get the User there.

For Example:

Controller

$someThing   = new SomeThing();
$someThing->setUser($user);
$form = $this->createForm(new someThingType(), $someThing);

Form

$someThing = $options['data'];
$user      = $someThing->getUser();
$builder->add('category', null, array(
    'class' => 'MyBundle:Cateogry',
    'query_builder' => 
        function(EntityRepository $er) use ($user) {
            return $er->getCategoriesForUser($user);
        }
));

Repository

public function getCategoriesForUser($user)
{
    $qb = $this->createQueryBuilder('c');
    $qb->leftJoin('c.user', 'u', 'with', 'u.user = :user');
    $qb->setParameter('user', $user)
    ;

    return $qb;
}

this is not exactly your use-case but pretty similar to it. maybe it helps you.
