I am using the form builder to create an choice-field form an entity looking like this:

$form->add(
                    'existing_items','entity', array(
                    'label' => 'Artikel aus',
                    'class' => 'ProjectShoppinglistBundle:Item',
                    'empty_value' => 'Bitte einen Artikel auswählen',
                    'property' => 'name',
                    'query_builder' => function(EntityRepository $er) use ($options) {
                        return $er->createQueryBuilder('item')
                            ->leftJoin('item.userItems', 'userItem')
                            ->where('userItem.user = ' . $options['attr']['id'])
                            ->orderBy('item.name', 'ASC');

                    },
                    'attr' => array(
                        'class' => 'form-control',
                    ),
                ));

but I am using jquery to change the content of the dropdown, so I need to change the validation for the field, how can I achieve that the values in the form are valid for all elements in the items-table and not just the one's which are linked to my the userId used in the query?

I have already taken a look at this but I still don't really get it how I can use the eventListener to get the desired result.

If someone could give me a useful hint, I would appreciate this very much.
