EntityManager closed because of s:convertEntity
Hello,
after getting such great help in my first question, I would like to ask another problem, depending on a selectOneMenu.
I use the following on my register.xhtml-page, so that people can select their title on registration:
<h:selectOneMenu value="#{registerAction.anrede}">
<s:convertEntity />
<s:selectItems var="anrede" value="#{registerAction.anredeSelect()}"
label="#{anrede.anrede}" noSelectionLabel="Select Anrede..."/>
</h:selectOneMenu>
When I send the registration form, I always get the following exception:
13:19:16,229 ERROR [viewhandler] Error Rendering View[/register.xhtml] java.lang.IllegalStateException: EntityManager is closed at

If I delte s:convertEntity out of my formular, I can submit it, but I only get a String as title.
This is the registerAction.java
@Stateless
@Name("registerAction")
// TODO @Restrict("#{not identity.loggedIn}")
public class RegisterAction implements Register {
@Logger
Log log;
private Anrede anrede;
private ArrayList<Anrede> anreden;
@EJB
private Benutzerverwaltung bv;
@PersistenceContext//(type = EXTENDED)
private EntityManager em;
@In
private transient FacesContext facesContext;
private String verify;
public RegisterAction() {
}
public List<Anrede> anredeSelect() {
ArrayList<Anrede> anreden = new ArrayList<Anrede>(bv.findAllAnreden());
return anreden;
}
public String register() {
log.info(anrede);
return "";
}
public void setAnrede(String a) {
this.anrede = a;
}
public String getAnrede() {
return this.anrede;
}
public String getVerify()
{
return verify;
}
public void setVerify(String verify)
{
this.verify = verify;
}I didn't change anything in components.xml or else where. I'm quiet new in Seam and hopefully someone can help me - explaining it in a simple way so that I can understand.
Thanks and best regards,
Dirk
