      Hi, i'm trying to delete a row from a datatable, but always the first row is removed.


      registerActionBean:


      @Stateful
      @Scope(ScopeType.SESSION)
      @Name("registration")
      public class RegisterActionBean implements RegisterActionLocal {
      
          
          @In
         private EntityManager em;
           
           
         @In(create=true)
         @Out
         private Customer customer;
         
      
         @DataModel(value="conta")
         private List<Contact> contacts;
         
         
         @DataModelSelection("conta") 
         private Contact selectedContact;
         
         @In(create=true,required=false)
         @Out(required = false)
         private Contact contact;
         
         
         @In
         private FacesMessages facesMessages;
         
         
      
           public void addContact() {
               contacts = (contacts==null)? new ArrayList<Contact>():contacts; 
               contacts.add(contact);
               contact = null;    
           }
      
           public void deleteContact (){
              
              contacts.remove(selectedContact);
          
          }
          
          
          
          @Remove
         public void destroy() {}
      }
