I've set-up a system which allows you to view categories of IT-equipment and their subcategories.
Now I want to be able to add a subcategory to a parentcategory via JPA.
The problem is that my entity is persisted correctly, but it does not show up in the dataTable. I need to start a new session to make it visible.
This is my xhtml-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">

<h:outputStylesheet library="css" name="tables.css"/>
<f:metadata>

</f:metadata>
</h:head>
<h:body>
<h:form>
<h:dataTable value="#{kategorieController.reload()}"
var="kat"
styleClass="katview">

<f:facet name="header">

<h:outputText value="#{kat.titel}"/>
</h:column>
<h:column>
<f:facet name="header">

</f:facet>
<h:selectManyCheckbox layout="pageDirection">
<f:selectItems value="#{kat.unterkategorieList}"
var="sub"
itemLabel="#{sub.titel}"
itemValue="#{sub.idunterkategorie}"/>
</h:selectManyCheckbox>
</h:column>
</h:dataTable>
<h:panelGroup>
<h:inputText value="#{kategorieController.titel}"/>
<h:selectOneMenu value="#{kategorieController.kategorie.idkategorie}">

</h:selectOneMenu>
<h:commandButton value="Add" action="#{kategorieController.addSub()}"/>
</h:panelGroup>
</h:form>
</h:body>
</html>
And these are my controllers in order to persist and relaod the data:
KategorieController:
package controller;
import java.io.Serializable;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.event.ComponentSystemEvent;

private Kategorie kategorie;
private String titel;
public void beforeRenderLoadKat(final ComponentSystemEvent event) {
if (allKats != null) {
allKats.clear();
}
allKats = katService.getAll();
subkategorie = new Unterkategorie();
kategorie = new Kategorie();
}
public void addSub() {
subkategorie.setKategorieId(kategorie);
subkategorie.setTitel(titel);
katService.addSub(this.subkategorie);
}
// GETTERS AND SETTERS
}
KategorieService:
package controller;
import java.io.Serializable;
import java.util.List;
import javax.ejb.Stateless;
import javax.ejb.TransactionAttribute;
import javax.ejb.TransactionAttributeType;
import javax.inject.Inject;
import model.Kategorie;
import model.Unterkategorie;
#Stateless
#TransactionAttribute(TransactionAttributeType.REQUIRED)
public class KategorieService implements Serializable {

private KategorieFacade katFacade;
public List<Kategorie> getAll() {
return katFacade.getAll();
}
public List<Kategorie> addSub(final Unterkategorie sub) {
return katFacade.addSub(sub);
}
}
KategorieFacade:
package controller;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.TypedQuery;
import model.Kategorie;
import model.Unterkategorie;
public class KategorieFacade {
#PersistenceContext
private EntityManager em;
public List<Kategorie> getAll() {
TypedQuery<Kategorie> query = em.createNamedQuery("Kategorie.findAll", Kategorie.class);
return query.getResultList();
}
public List<Kategorie> addSub(final Unterkategorie sub) {
em.persist(sub);
em.flush();
return getAll();
}
}
Any help is appreciated!
Thank you in advance!
Why don't you try to refresh the collection in the addSub() method:
public void addSub() {
subkategorie.setKategorieId(kategorie);
subkategorie.setTitel(titel);
allKats.clear();
allKats.addAll(katService.addSub(this.subkategorie));
}
And completely unrelated to the original question: you're interchanging the concepts Service and Facade with each other.
But I would suggest that instead of putting the getAll() into addSub(), make it void and do another call from the client to the service after doing the insertion.

The error appear when i change the page view, in pagination have (1,2,3...) if i check the radio button in page '1' and i go to page '2' and i come back to page '1' the radio button is not checked.
Why does it happen?
How do i fix it?
I need to keep the value checked in the radioButtons.
I resolved using this.
I create 2 SelectoneRadio, one geting the checked value, if exists..
And another only puting the value.
I use Ajax to pass the ID.
If the map contains the id, i use ajax only to update, because the radio set the value directly in the map.

After put a answer and ID, you need to make the value 'teste' null.

I have created a session bean but it seems my <h:selectOneMenu> is not storing the value in the bean. Can someone tell me what I am doing wrong?
In the xhtml navigates to another xhtml that displays the results. I do not have any values in faces-config.xml other than the navigation rules since I think managed bean / session bean annotations can replace that

}
}
The problem is in the converter you're using. The field of your managed bean from where you're getting/setting the data is of type Long and the default value for <h:selectOneMenu> is of type String, so you only need to use a Long converter. There's a built-in converter for this case: javax.faces.Long. Make sure you're defining that the itemValue for the <h:selectItems> is type Long as well.
The code should look like this:
<h:selectOneMenu id="mypick"
value="#{gridMaster_backing.pickedGrid}"
converter="javax.faces.Long"
title="ADTF">
<!-- #{prog.gridid} must return Long -->
<f:selectItems
value="#{gridMaster_backing.gridList}"
var="prog"
itemValue="#{prog.gridid}"
itemLabel="#{prog.gridid} - #{prog.program} - #{prog.project} - #{prog.ci}" />
</h:selectOneMenu>

I am not able to add textBox by clicking the add button. Please help. Thanks in advance.
You need to put the whole in a <h:form>. See also commandButton/commandLink/ajax action/listener method not invoked or input value not updated.
Another major mistake is here:
<h:dataTable ... binding="#{utilBean.data}">
...
<h:inputText ... binding="#{utilBean.attachment}"/>
Remove those binding attributes. UI components are request scoped and yet you're binding them to a session scoped bean. This would fail hard if you open the same page in multiple browser windows in the same session. See also How does the 'binding' attribute work in JSF? When and how should it be used?.
That said, the #ManagedBean #SessionScoped on AttachmentBean is completely unnecessary. Get rid of those annotations. The #SessionScoped on UtilBean is also rather strange. The #ViewScoped is much better at its place here. See also How to choose the right bean scope?
it's my first question on the site :) But first, sorry for my bad english, i'm learning :)
Plz, i need your help. I'm blocked with an application in JSF.

This makes your managed bean to have the default scope, which in JSF 2 is #RequestScoped, so your managed bean will be re created on every request.
Fix your import to:
import javax.faces.bean.SessionScoped;
If you happen to use JSF 2.2.x, start working everything with CDI 1.1. Use #Named for your managed beans and use javax.faces.view.ViewScoped for #ViewScoped.

What's new in JSF 2.2. CDI compatible #ViewScoped
