[patrickcr]

Hi guys i am a new user from seam framework and i want to now how to retrieve data to a modal panel from the datable. I now there is some information over the web about is, buit i have try 100 thins i dosent work. so there is my bean;



@Name("usersList")
public class UsersList implements Serializable{
/**
      *
      */
     private static final long serialVersionUID = -8191663213732129820L;


    @Logger private Log log;
    public Users userSelected= new Users();
    private Collection<Users> usersList = new ArrayList<Users>(0); 
    @In StatusMessages statusMessages;
     private Set <Integer>keys;
   
    public void usersList()
    {
         try {
              
              EntityManagerFactory emf =Persistence.createEntityManagerFactory("projectseam2");          
              EntityManager em = emf.createEntityManager();         
              String query = "select x from Users x where x.name like '%" + value +"%'";
              usersList = em.createQuery(query).getResultList();
              em.close();     
              } catch (Exception e) {
                   // TODO Auto-generated catch block
                   statusMessages.add(getFullExceptionMessage(e));
              }
    }

    public Collection<Users> getUserlist()
    {
          return usersList;

    }


    public void getCurrentRow(Users user) {
     
     }
    public Set<Integer> getKeys() {
          return keys;
     }

     public void setKeys(Set<Integer> keys) {
          this.keys = keys;
     }

   
    public static String getFullExceptionMessage(Exception e) 
    { 
        String message = e.getLocalizedMessage();  
         Throwable t = e.getCause(); 
         while(t != null)  
         { 
            message += "\n" + t.getMessage();  
            t = t.getCause(); 
         }        
         return message;

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

}
.. i dont now what is the problem because i get the data wheni call the method userlist in userlist.java and then i can execute any actions with the link on the datable. It dosent call the  usersList.currentRow on
      <f:setPropertyActionListener value="#{user}"
                          target="#{usersList.currentRow(user)}" /> .

i try a system.out.print in this method but it never works.

please if you have any ideia, please tell-me

.

Best regards

I think you misunderstood the function of f:setPropertyActionListener (It's all about getter and setters).

UsersList.java:

@Name("usersList")
public class UsersList implements Serializable {
// ...

    private Users currentUser;

    public Users getCurrentUser() {
        return this.current;
    }

    public void setCurrentUser(Users user) {
        this.currentUser = user;
    }

// ...
}

usersList.xhtml should be:

<a:commandLink value="editar" reRender="modal"
  oncomplete="#{rich:component('modal')}.show()">
    <f:setPropertyActionListener value="#{user}" target="#{usersList.currentUser}" />
</a:commandLink>

<rich:modalPanel id="modal" ...>
    <!-- ... -->
    <h:outputText value="#{usersList.currentUser.name}" />
    <!-- ... -->
</rich:modalPanel>

If you want to call an action out of your modal panel, you should place a form into it.

You also may want to check out the Richfaces example to edit a table with a modal panel

This is what both @DataModel and @DataModelSelection were designed for.
See Clickable lists in Seam for a great explanation.

Hi guys, i tried used Datamodel and DatamodelSelection but now i have some other problems, firt i cannot the new instance of the classe user, i must put the values manually, like this,

public void selectUser(Users current){
         
         currentUser.setIdutilzadores(current.getIdutilzadores());
         currentUser.setName(current.getName());
         currentUser.setUsername(current.getUsername());
         currentUser.setPassword(current.getPassword());
         
    }

second when i try to update or remove, on the the datable it chenge me the firt row in the datable with current row selected, but if i refresh the list it becommes update or deleted.
i put the code for have a better perpective.

my bean:

 */
@Name("user")
@Entity
@Table(name = "users", catalog = "jbossformacao")
public class Users implements java.io.Serializable {

     private int idutilzadores;
     private String username;

     private String name;

     public Users() {
     }

     public Users(int idutilzadores, String username, String password,
               String name) {
          this.idutilzadores = idutilzadores;
          this.username = username;

          this.name = name;
