I have a @ConversationScoped CDI Managed Bean in my JSF application, using Primefaces 5.2 running on Wildfly 8.2.1 . Implicit navigation is just working once in my application. First, i have my index.xhtml which has a button that calls my managed bean, CiudadManagedBean:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui">
<ui:composition template="/plantilla/template.xhtml">
<ui:define name="contenido">
<h:form>
<p:commandButton action="#{ciudadMB.cargarCiudades()}"
value="Mostrar ciudades" />
</h:form>
</ui:define>
</ui:composition>
</html>
Next, here is CiudadesManagedBean. As you can see, i start a conversation on @PostConstruct method and it loads a list when i call cargarCiudades from index.xhtml, and finally it loads ciudades/lista.xhtml:
package com.saplic.fut.beans;
import java.io.Serializable;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.enterprise.context.Conversation;
import javax.enterprise.context.ConversationScoped;
import javax.inject.Inject;
import javax.inject.Named;
import com.saplic.fut.daos.CiudadDAO;
import com.saplic.fut.entity.Ciudad;
@Named(value="ciudadMB")
@ConversationScoped
public class CiudadManagedBean implements Serializable {
private static final long serialVersionUID = 7339176875158769385L;
private Ciudad instance;
private List<Ciudad> cities;
private Integer idCity;
@Inject
private CiudadDAO ciudadDAO;
@Inject
private Conversation conversation;
@PostConstruct
public void inicializarConversacion() {
if(conversation.isTransient())
conversation.begin();
}
public Ciudad getInstance() {
return instance;
}
public String cargarCiudades() {
setCities(ciudadDAO.cargarCiudades());
return "ciudades/lista";
}
public String cargar() {
Ciudad flt = new Ciudad();
flt.setId(getIdCity());
setInstance(ciudadDAO.cargarDetalle(flt));
if(getInstance() == null)
setInstance(new Ciudad());
return "ciudades/detalle";
}
public String guardar() {
ciudadDAO.guardar(getInstance());
setCities(ciudadDAO.cargarCiudades());
return "ciudades/lista";
}
public String actualizar() {
ciudadDAO.actualizar(getInstance());
setCities(ciudadDAO.cargarCiudades());
return "ciudades/lista";
}
public String eliminar() {
ciudadDAO.guardar(getInstance());
setCities(ciudadDAO.cargarCiudades());
return "ciudades/lista";
}
public void setInstance(Ciudad instance) {
this.instance = instance;
}
public List<Ciudad> getCities() {
return cities;
}
public void setCities(List<Ciudad> cities) {
this.cities = cities;
}
public Integer getIdCity() {
return idCity;
}
public void setIdCity(Integer idCity) {
this.idCity = idCity;
}
}
Finally, the xhtml where i call my method cargar(). I want to invoke that method and then load ciudades/detalle.xhtml because here's my form.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui">
<ui:composition template="/plantilla/template.xhtml">
<ui:define name="contenido">
<h:form id="frm1">
<p:dataTable id="tablita" resizableColumns="true" rowIndexVar="rowIdx"
paginator="true" rows="10" paginatorPosition="bottom" value="#{ciudadMB.cities}"
var="ciu" >
<p:column headerText="Código pais">
<p:outputLabel value="#{ciu.codigoPais}" />
</p:column>
<p:column headerText="Distrito">
<p:outputLabel value="#{ciu.distrito}" />
</p:column>
<p:column headerText="Nombre">
<p:outputLabel value="#{ciu.nombre}" />
</p:column>
<p:column headerText="Población">
<p:outputLabel value="#{ciu.poblacion}" />
</p:column>
<p:column headerText="Accion">
<p:commandLink action="#{ciudadMB.cargar()}" ajax="false" value="Ver" process="@form">
<f:setPropertyActionListener value="#{ciu.id}" target="#{ciudadMB.idCity}" />
</p:commandLink>
</p:column>
</p:dataTable>
</h:form>
</ui:define>
</ui:composition>
</html>
When i click on a link inside my datatable, it invokes ciudadMB.cargar() and executes the code inside it, but it ignores the return "ciudades/detalle" . So, implicit navigation works at first time (when i'm on index.xhtml and i click the buttons, it takes me to lista.xhtml) but when i click on a link to go to detalle.xhtml, it ignores it. It just refresh lista.xhtml. Also, I've tried with @SessionScoped and @RequestScoped (always using javax.enterprise.context annotations instead JSF annotations, and removing Conversation object and initialization).
With @SessionScoped it has the same behavior. Pagination works without problems but when i click on the commandLink inside datatable it invokes the action method but ignores the String return.
With @RequestScoped if i click the commandLink it refreshes the page but doesn't invoke the action method. If i put a dummy commandLink outside the datatable it invokes the action method but again, it ignores the String return.
Why Implicit Navigation is not working? Is some CDI issue? Regards.
EDIT: I also changed the annotations to import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; to check if it was about CDI annotations, but it didn't work either, so it isn't a problem of CDI. Do i have to activate something in my configuration to make it work? This is a Eclipse Dynamic Web Project 3.1, JPA 2.1 and JSF 2.2 running on Wildfly 8.2.1 . Here is my web.xml configuration file:

You are using relative navigation. Try with
return "detalle";
instead of
return "ciudades/detalle";
Or use absolute navigation instead:
return "/ciudades/detalle";

Finally, i tried something: I haven't set JSF parameter "PROJECT_STAGE" in my web.xml file, so i set it in development mode:
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
After that, i've tried again and i got this error:
09:58:58,487 WARNING [javax.enterprise.resource.webcontainer.jsf.application] (default task-21) JSF1064: Unable to find or serve resource, /ciudades/ciudades/detalle.xhtml.
The problem is that i was using a relative path. The first time, moving from index.xhtml to ciudades/lista.xhtml, it worked without problem because i was in the root path (http:localhost:8094/SistemaFutJsf), but after that, when i was trying to go to ciudades/detalle.xhtml, the application context was this (http:localhost:8094/SistemaFutJsf/ciudades) and because of that it couldn't find /ciudades/ciudades/detalle.xhtml.
So, the solution was to add a slash (/) to make the paths absolute, like this:
public String cargarCiudades() {
setCities(ciudadDAO.cargarCiudades());
return "/ciudades/lista";
}
public String cargar() {
Ciudad flt = new Ciudad();
flt.setId(getIdCity());
setInstance(ciudadDAO.cargarDetalle(flt));
if(getInstance() == null)
setInstance(new Ciudad());
return "/ciudades/detalle";
}
