Entityhome.remove() causes "deleted entity passed to persist"

rituraj_tiwari Mar 21, 2008 11:11 PM

Folks,
I have an entity that represents a user that can have multiple email addresses associated with them in a bidirectional one to many relationship:

@Entity
public class EndUser implements Serializable
...
    @OneToMany(cascade={CascadeType.ALL}, fetch = FetchType.EAGER, mappedBy="user")
    @IndexColumn(name="id")
    public List<Email> getEmails()
    {
        return m_emails;
    }

The email entity looks like this:

@Entity
public class Email implements Serializable 
{
     
     @ManyToOne
     @JoinColumn
     public EndUser getUser()
     {
          return m_user;
     }
...

I am not quite sure how to let a user delete an email address associated with them. My current incarnation of the EndUserHome.deleteEmail() method does the following:

@Name("endUserHome")
public class EndUserHome extends EntityHome<EndUser>

    public boolean deleteEmail(String sEmailUid) 
    {
     EndUser user = getInstance();
     Email toDelete = null;
     for(Email email : user.getEmails())
     {
         if(email != null && email.getUid().equals(sEmailUid))
         {
          toDelete = email;
          break;
         }
     }
          
     if(toDelete != null)
     {
         EmailHome emailHome = (EmailHome)Component.getInstance(EmailHome.class);
         emailHome.setInstance(toDelete);
              
         emailHome.remove();
            user.getEmails().remove(toDelete);
            return true;
     }
        return false;

The above fails at emailHome.remove() with

I thought I was taking the recommended and safe route by using entity homes and Seam application framework. Any idea what I am doing wrong?

Thanks.

Nothing to do with EntityHome but just your undestanding of how you delete cascading relationships. Best to ask to on the hibernate forum (n.b. you shouldn't need any special code for this).
