Hi, I have a seam-gen app, in the edit form I inserted the following code:
| <s:decorate template="layout/edit.xhtml">
| <ui:define name="label">Stato</ui:define>
| <h:selectOneMenu id="stato" value="#{articoloHome.instance.statoArticolo}" required="true">
| <s:selectItems value="#{articoloHelper.getStatiArticolo(articoloHome.instance.tipologiaArticolo.id)}" var="stato" label="#{stato.descrizione}" noSelectionLabel="Seleziona lo stato..."/>
| <s:convertEntity />
| </h:selectOneMenu>
| </s:decorate>
|
It call the getStatiArticolo function that is in articoloHelper (Seam POJO, Scope=CONVERSATION):
| private List<StatoArticolo> statiArticolo;
|
| public List<StatoArticolo> getStatiArticolo(int idTipologia)
| {
| if (statiArticolo==null) {
| statiArticolo = (List<StatoArticolo>) entityManager.createQuery(
| "from StatoArticolo sa WHERE sa.tipologiaArticolo.id = "+idTipologia+" ORDER BY sa.descrizione").getResultList();
| }
|
| return statiArticolo;
| }
|
The menu and its items are rendered fine, the selected item works, but when I click on submit I got a strange error:

But StatoArticolo is a working entity (the form for example is showed well)...
what can it be?
Thanks
