    private Integer id;
    private Integer ownerId;
    private String name;

Answer 1

try this:

    Criteria crit = getCurrentSession().createCriteria(Album.class, "album");
    crit.add(Restrictions.idEq(albumId));
    if (picFilter != null && !picFilter.isEmpty()) {
        crit.createAlias("album.pictures", "picture");
        crit.createAlias("picture.event", "event");
        crit.add(Restrictions.in("event.id", picFilter));
        crit.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);   
    }
