Hi!

I do have the following classes:

@Entity
@Table(name = "daDomain")
@Name("domain")
public class Domain implements Serializable
{

     @Override
     public int hashCode() {
          ...
     }

     @Override
     public boolean equals(Object obj) { ... }

     
     private static final long serialVersionUID = 1L;
     private int id;
    private String name;
    private List<MailUser> mailuser;
    
    @DataModel
    @OneToMany(targetEntity = MailUser.class)
    @JoinColumn(name = "intDomainID", referencedColumnName = "intDomainID")
    public List<MailUser> getMailuser() {
          return mailuser;
     }

     public void setMailuser(List<MailUser> mailuser) {
          this.mailuser = mailuser;
     }

 
    @Id @GeneratedValue @Column(name="intDomainID")
    public int getId() {
        return id;
    }

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

    @Column(name="strDomain",unique=true)
    @Length(max=20,min=6)
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }  
}

and

@Entity
@Table(name = "daMailUser")
@Name("mailUser")
@Scope(ScopeType.EVENT)
public class MailUser implements Serializable
{
     @Override
     public int hashCode() {..}

     @Override
     public boolean equals(Object obj) {..}
     private int id;
     private String username;
     private String password;
     private Domain domain;
     
     private static final long serialVersionUID = 1L;
     
     @Id @GeneratedValue
     @Column(name = "intMailUserID")
     public int getId() {
          return id;
     }
     public void setId(int id) {
          this.id = id;
     }
     @Column(name = "strUsername")
     public String getUsername() {
          return username;
     }
     public void setUsername(String username) {
          this.username = username;
     }
     @Column(name = "strPassword")
     public String getPassword() {
          return password;
     }
     public void setPassword(String password) {
          this.password = password;
     }
     
     @ManyToOne
     @JoinColumn (name = "intDomainID")
     public Domain getDomain() {
          return domain;
     }
     public void setDomain(Domain domain) {
          this.domain = domain;
     }
}

I do have a datatable filled with MailUsers. In an event scoped bean I defined a function

public String delete(MailUser objMailuser)
     {
          objMailuser = em.merge(objMailuser);
          em.remove(objMailuser);
          em.flush();
     }

while domain the current (injected) domain is.

This procedure works sometimes, but most times (as I can see from hibernate log) the entity is deleted and then recreated (reinserted). Another issue is, that the datatable, that is bound to 'domain.mailUsers' isn't refresehd.

Do you know what I can do to fix these two issues?

Thank you in advance!
