dataModel dataModelSelection first row

[yacin00]

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() {}
}

s:link doesn't post and could cause problems. Try deleting with a h:commandLink.

[yacin00]

same thing happens with h:commandLink, just the first row is deleted, (after the validation of the field).

Hi,
oops, i resolved the problem and I've forgotten to post the solution
the problem was that my entities were not persisted, and because of the List methods were based on the method equals , it didn't work.
i used a comparator for comparing and a Collections.binarySearch for match a selected dataModelSelection with the removed one.
I think , some simpler solution exist, something which allow to search an element in a no persisted list.
I'll tell you if I find something more interesting .

s:link propagates data model selection

sorry, but i don't figure out  what do you mean by that ??
