Hi,

I've created an Entity 'User', which holds a property "cookie". "cookie" has to be stored in the database lowercase. I want to outsouce this functionality in a class "Data".

Code:
@Entity
@Table(name = "USERS")
public class User {

   @Id
   @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "user_id_seq")
   @SequenceGenerator(name = "user_id_seq", sequenceName = "user_id_seq")
   private long id;

   @Column(length = 50, nullable = false, unique = true)
   private String email;

   @Column(length = 50, nullable = false)
   private String firstName;

   @Column(length = 50, nullable = false)
   private String lastName;

   public long getId() {
      return id;
   }

   public void setId(long id) {
      this.id = id;
   }

   public String getEmail() {
      return email;
   }

   public void setEmail(String email) {
      this.email = email;
   }

   public String getFirstName() {
      return firstName;
   }

   public void setFirstName(String firstName) {
      this.firstName = firstName;
   }

   public String getLastName() {
      return lastName;
   }

   public void setLastName(String lastName) {
      this.lastName = lastName;
   }

   public User() {
   }

   public User(String email, String firstName, String lastName) {
      this.email = email;
      this.firstName = firstName;
      this.lastName = lastName;
   }

   @Embeddable
   public static class Data {

      @Column(length = 50, unique = true)
      private String data;

      public Data(String data) {
         setData(data);
      }

      public String getData() {
         return data;
      }

      public void setData(String data) {
         this.data = data.toLowerCase();
      }
   }

   @Embedded
   private Data cookie;

   public Data getData() {
      return cookie;
   }

   public void setData(Data cookie) {
      this.cookie = cookie;
   }

}

If I save the entity without assigning a value to "cookie" it works.
Code:
@Test
public void thisWorks() {
   USER = new User(EMAIL, FIRSTNAME, LASTNAME);
   daoUnderTest.save(USER);
}

Code:

BUT if I set "cookie" to some data, something goes wrong. Hibernate is creating an UPDATE instead of an INSERT statemeant. I'm using Spring HibernateDaoSupport which calls em.save(entity)
Code:
@Test
public void problemHere() {
   USER = new User(EMAIL, FIRSTNAME, LASTNAME);
   USER.setData(new User.Data("joh"));
   daoUnderTest.save(USER);
}

Any ideas?

The problem was a missing default constructor in the class "Data".

You guys should fix that error message!
