jsfcommandbutton

h:commandButton is not working - action

I am making an application using jsf and I have a problem when sending data from one of the rows of the datatable to a bean and then redirect to another page. Just to state, I'm using bootsfaces. Here are the codes:

JSF page:

            </b:column>

        </b:dataTable>

LanceMB code:

@SessionScoped
@ManagedBean(name="LanceMB")
public class NovoLance {
    private Usuario user = new Usuario();
    private LancesLeilao ll = new LancesLeilao();
    private double novo_valor;


    public String lance(Usuario usuario, LancesLeilao lal){
        this.user = usuario;
        this.ll = lal;
        return "novolance";            
    }

    //getters.. setters
   }

Usuario code:

@ManagedBean(name="Usuario")
@SessionScoped
public class UserSession {
    private String email, senha;
    private Usuario user = new Usuario();

//getters and setters..
}

Any question leave a comment.

Solution

  • A <h:commandButton /> is used to push the values of individual fields in a form to the managed bean defined. I see that you have enclosed just the button within the form but not the values themselves.

    Wrap all the values within the form including the button and give it a try. It should work if everything else has been defined correctly.

    Hope this helps :)
