selectOneMenu problem

[demetrio812]

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

I also tried to do not use the method and use component definition in components.xml, if I don't use a value of the instance of articoloHome it works, like that:

 <framework:entity-query name="statoArticoliAll"
 entity-manager="#{entityManager}"
 ejbql="select sa from StatoArticolo sa WHERE sa.tipologiaArticolo.id=2"
 order="descrizione"
 scope="conversation">
 </framework:entity-query>

I manually coded the "2" value of the id of tipologiaArticolo (that's wrong, I need dynamic value).

In the right way I need it doesn't works and give me the same error:

 <framework:entity-query name="statoArticoliAll"
 entity-manager="#{entityManager}"
 ejbql="select sa from StatoArticolo sa"
 order="descrizione"
 scope="conversation">
 <framework:restrictions>
 <value>tipologiaArticolo = #{articoloHome.instance.tipologiaArticolo}</value>
 </framework:restrictions>
 </framework:entity-query>

So I think the problem is in articoloHome (seam-gen generated class that extends EntityHome).

Any ideas?

Thanks!

What version of Seam?

[demetrio812]

2.0B1, but it was a version of the july 9th...

so I'm tring with the latest one but I got some problem (see also http://www.jboss.com/index.html?module=bb&op=viewtopic&t=116726)

Thank for helping!

Please post the stack trace when you try this with current CVS.

[demetrio812]

I wanted to try with current CVS but I can't because it doesn't deploy coz of the other error and I need message bundles (the page that give me the error use them)...

So I'm waiting to solve the resourceBundle problem and then I will test it...

see the link I putted in the other post for further details...

thanks

[demetrio812]

I updated the project and it works now!!

Sorry for all the time you lost following me...

another little question:

I have a component in application scope:

 <framework:entity-query name="linguaAll"
 entity-manager="#{entityManager}"
 ejbql="select lingua from Lingua lingua"
 order="Descrizione"
 scope="application">
 </framework:entity-query>

I putted in application because it doesn't change after startup...

If I use it in a selectOneMenu in this way:

 <h:selectOneMenu id="lingua" value="#{articoloHome.instance.lingua}" required="true">
 <s:selectItems value="#{linguaAll.resultList}" var="lingua" label="#{lingua.descrizione}"/>
 <s:convertEntity />
 </h:selectOneMenu>

It give me the "Value is not valid" error...

if I put the component in conversation scope it works, but I thought that application scope was fine coz it is longer than conversation scope, where do I wrong? and if application scope is bad how can I do to do not reload from DB at every new conversation?

Thanks again!

Read the SeamProblemsFAQ on the wiki

[demetrio812]

Hi, thanks again...

I read it yesterday and I thought that giving that application scope is longer then conversation scope it would work...

now I read it again that line:

Ensure that you are in a long-running conversation that spans the both the select list creation and the submission of the form.

So maybe I must use the same conversation? (so the same JPA session?) is there a way to leave the component on application scope and then merge it in conversation scope?

other ideas on how to implement this?

Thanks

Yes.

You have to implement equals()

[demetrio812]

I see...

Thank you very much for your answers!!
