Ebean is not cascading persistence with Play-2.5(OneToMany)

Here are my models.

User: 

@Entity
@Table(name="users")
public class User extends Model {
  String username;
  @Id
  String id;
  @OneToMany(cascade = CascadeType.ALL)
  List<Tag> tags;
}

Tag:

@Entity
@Table(name="tags")
public class Tag extends Model {

  @Constraints.Required
  public String tag;
}

Persistence code(Removed unnecessary code):

User user = new User();
user.id = UUID.randomUUID().toString();
user.username = username; // String
user.tags = tags; // list of tags;
Ebean.save(user);

I am calling Ebean.save(user) after adding tags to user object. Tags added on user are not persisted to database. I am also not seeing any exception, other fields of user get persisted but not tags. Am I missing something?

Note: I am using postgres.

Thanks for the suggestion @marcospereira. I was missing id field in Tag model. After enabling debugging and sql logging I noticed warning in logs. The correct way to create Tag class:

@Entity
@Table(name="tags")
public class Tag {
  @Id
  @GeneratedValue
  public String id;
  public String tag;
}

but It is weird why Ebean is doing that.

Hope this helps someone in future.
