при поиске некоторых объектов в модуле CRUD Play я получаю следующее исключение:

Странно то, что поиск работает для некоторых объектов, а не для других. Например, для следующего объекта работает добавление любой строки в поле поиска:
@Entity
public class Act extends Model {
@Transient
private static final int PAGE_SIZE = Integer.parseInt(Play.configuration.getProperty("pagination.size","10"));
@Required(message = "act.name.required")
public String name;
@Required(message = "act.description.required")
@Lob
@MaxSize(value=500, message="act.description.maxsize")
public String description;
public Blob image;
public boolean showInClosedMode;
@Temporal(TemporalType.TIMESTAMP)
public Date updated;
@Required(message = "act.theatre.required")
@ManyToOne
public Theatre theatre;
public boolean disabled;
@OneToMany(mappedBy="act")
public List<Offer> offers;
@ManyToMany(cascade=CascadeType.PERSIST)
public Set<Tag> tags;
@Transient
public String tagListSupport;
[... some methods ...]
}
Но не для этого:
@Entity
public class User extends Model {
@Required(message = "user.name.required")
public String name;
@Email(message = "user.email.invalid")
public String email;
public String prefLang;
public Long prefCity;
public int credits;
public Date lastLogin;
@NoBinding("profile")
public boolean disabled;
@NoBinding("profile")
public boolean admin;
@NoBinding("profile")
public boolean anonymous;
@OneToMany(mappedBy = "owner")
public List<Ticket> tickets;
@ManyToMany
public List<Theatre> theatres;
public String googleId;
public String yahooId;
public String facebookId;
public String twitterId;
public String twitter_token;
public String twitter_secret;
public String username;
public String password;
@OneToMany(mappedBy = "user")
public List<Event> history;
[...Methods...]
}
Есть идеи, почему это происходит?
