    empty values in extendedDataTable [RF 4.3.4]

    Kamil Roman Newbie

      Hi,

      In some cases when I use rich:extendedDataTable I get empty cells in the table - the cells are literally empty, even in the rendered <h:link> with <f:param name="#{entityId}" value="#{entity.id}"/> the param value for entityId is set to 0. For all rows. However, what is quite weird, the number of displayed rows is correct. This only happens when I go to the page as a result of performing an action on another page (and another bean) - the issue does not happen when accessing the page with plain <h:link/>  Am I doing something wrong?

       

      Relevant code:

      @Named

      @RequestScoped

      public class EntityListController {

       

          @Inject

          private EntityRepository repository;

       

          private Iterable<Entity> list;

       

          @PostConstruct

          private void init() {

               list = repository.findAll();

          }

       

          public Iterable<Entity> getParafie() {

              return list;

          }

      }

      and the page:

       

      <?xml version="1.0" encoding="UTF-8"?>

      <!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:f="http://java.sun.com/jsf/core"

            xmlns:h="http://java.sun.com/jsf/html"

            xmlns:ui="http://java.sun.com/jsf/facelets"

            xmlns:rich="http://richfaces.org/rich">

       

      <h:body>

          <ui:composition template="/WEB-INF/templates/template.xhtml">

              <ui:define name="title">EntityList</ui:define>

              <ui:define name="content">

                  <h:link outcome="addEditEntity" value="Add entity"/>

                  <h1>Entities</h1>

                  <rich:messages globalOnly="true"/>

                  <rich:extendedDataTable id="entityTable" value="${entityListController}" var="entity">

                      <rich:column>

                          <f:facet name="header">Name</f:facet>

                          <h:link value="${entity.name}" outcome="addEditEntity">

                              <f:param name="entityId" value="#{entity.id}"/>

                          </h:link>

                      </rich:column>

                  </rich:extendedDataTable>

              </ui:define>

          </ui:composition>

      </h:body>

      </html>

       

      The issue happens when I try to access the page returning from an action:

      <h:commandButton action="#{addEditEntityController.save}" value="Save"/>

       

      public String save() {

                  repository.save(parafia);

                  messages.addInfo().DataSavedSuccessfully();

                  return "index";

      }

      When I access the page via

      <h:button outcome="index" value="Powrót"/>

      the extendedDataTable is rendered correctly. The AddEditEntityController is a ViewScoped bean.
