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

    Raj Tiwari Newbie

      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.
