Code

function relation_dummy_field_field_prepare_view($entity_type, $entities, $field, $instances, $langcode, &$items, $displays) {
  foreach ($entities as $id => $entity) {
    $relation_types = $instances[$id]['settings']['relation_type'];
    $query = relation_query($entity_type, $id)
      ->range(0, 50);

        ->condition('relation_type', $relation_types, 'IN');
    }
    $relation_ids = array_keys($query
      ->execute());

    // Who knows why but field does not like if the delta does not start at 0...

    foreach (Relation::loadMultiple($relation_ids) as $relation) {
      $items[$id][] = (array) $relation;
