Primefaces DataTable not rendering at all

Question

I have a <h:dataTable> that renders perfectly, but when I change it to p:dataTable it vanishes completely

Unfortunately I am not able to upload images yet, but other PrimeFaces components on the same page are rendering perfectly.

Here is the XHTML file:

            </h:form>

        </ui:define>

    </ui:composition>


</body>
</html>

and here is the bean:

package DataAccess;

import Entities.Application;
import java.util.List;
import javax.ejb.Stateless;
import javax.inject.Named;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;


@Stateless
@Named
public class ApplicationFacade extends AbstractFacade<Application> {
    @PersistenceContext(unitName = "com.mycompany_WSAMS_war_1.0-SNAPSHOTPU")
    private EntityManager em;

    @Override
    protected EntityManager getEntityManager() {
        return em;
    }

    public ApplicationFacade() {
        super(Application.class);
    }

    public List<Application> getApplications() {
        return em.createNamedQuery("Application.findAll").getResultList();
    }    
}

I am using primefaces lib 4.0, does anyone know how to fix this issue, if it helps the primefaces selectOneMenu and radio buttons do not allow me to interact with them.

Are you getting any exception when page rendered ? – JavaBeigner Aug 25 '14 at 05:13 — JavaBeigner, Aug 25 '14 at 05:13

Change the h:column tags to p:column (Primefaces columns). After changing that, the datatable rendered for me.

You can even shorten the column definitions to:

<p:column headerText="Applicationid">
   <h:outputText value="#{item.applicationid}"/>
 </p:column>

You need to add the <h:panelGrid id="yourID"> around your dataTable. When </h:panelGrid> is closed then you can place your <p:commandButton update="yourID" action="yourAction"/>

Because, prime rendered only when you call to render. Else the content would rendered when you reload the page.

Hope this is helpfull

This does not make sense to me. You most likely refer to https://stackoverflow.com/questions/9010734/why-do-i-need-to-nest-a-component-with-rendered-some-in-another-component-w but that does not play a role here. Not at all – Kukeltje Apr 29 '20 at 10:55
