Weird behaviour when submit using @Out property

[fmontezuma]

Hi!

I´m having problems when I try to set a value to my bean.

I want to set the current classification value to it, but somehow it's having a weird behavior.

Here is the code:

@Name("classificacaoAction")
@Scope(ScopeType.CONVERSATION)
public class ClassificacaoAction
{
     @In(create = true)
     private List<SofClassificacao> listaClassificacoes;
     
     @Out(required = false)
     private SofClassificacaoRomaneio classificacaoAtual;
     
     @In
     private GerenciarRomaneioAction sofGerenciarRomaneioAction;
     
     @Out
     private SofRomaneio romaneio;
          
     @Factory(value = "romaneio", autoCreate = true)
     public void carregarRomaneio()
     {          
          romaneio = sofGerenciarRomaneioAction.getRomaneio();
          
          // inicializa classificacoes
          if (romaneio.getSofClassificacaoRomaneios().isEmpty())
          {
               romaneio.setSofClassificacaoRomaneios(new LinkedHashSet<SofClassificacaoRomaneio>());
               Set<SofClassificacaoRomaneio> lista = romaneio.getSofClassificacaoRomaneios();
               
               for (SofClassificacao classificacao : listaClassificacoes)
               {
                    SofClassificacaoRomaneio classificacaoRomaneio = new SofClassificacaoRomaneio();
                    classificacaoRomaneio.setSofRomaneio(romaneio);
                    classificacaoRomaneio.setSofClassificacao(classificacao);
                    classificacaoRomaneio.setPcDesconto(BigDecimal.ONE);
                    lista.add(classificacaoRomaneio);
               }
          }
          classificacaoAtual = romaneio.getSofClassificacaoRomaneios().iterator().next();
     }     
          
     public void proximaClassificacao()
     {
          if (classificacaoAtual != null)
          {
               Integer classificacaoAtualId = classificacaoAtual.getId().getCdClassificacao();
               
               Iterator<SofClassificacaoRomaneio> i = romaneio.getSofClassificacaoRomaneios().iterator();
               SofClassificacaoRomaneio cr = i.next(); // 1o valor - nunca será satisfatório
               
               while (i.hasNext() && cr.getId().getCdClassificacao() <= classificacaoAtualId) 
               { 
                    cr = i.next();
               }
               
               if (cr.getId().getCdClassificacao() > classificacaoAtualId)
               {
                    classificacaoAtual = cr;
               }
               else
               {
                    classificacaoAtual = null;
               }
          }
     }          
}

And the page (it is included in another page, there is a form around it):

<rich:tab label="Classificação" id="gr-aba-classificacao"
    xmlns="http://www.w3.org/1999/xhtml"

    xmlns:s="http://jboss.com/products/seam/taglib"
    xmlns:a="http://richfaces.org/a4j"
    xmlns:rich="http://richfaces.org/rich">
     
     <s:div id="classif-romaneio" rendered="#{editarRomaneio}">
     
          <s:decorate id="classificacaoAtualField" template="layout/custom-edit.xhtml" rendered="#{classificacaoAtual != null}">
               <ui:define name="label">#{classificacaoAtual.sofClassificacao.dsClassificacao}</ui:define>
               <h:inputText value="#{classificacaoAtual.psDesconto}" />               
          </s:decorate>
          
          <a:commandButton action="#{classificacaoAction.proximaClassificacao}" value="Salvar" rendered="#{classificacaoAtual != null}">
               <a:support event="oncomplete" reRender="classif-romaneio, tblClassificacoes" />
          </a:commandButton>
          
     </s:div>
          
     <rich:dataTable id="tblClassificacoes" 
          value="#{romaneio.sofClassificacaoRomaneios.toArray()}" var="_classif">
          <rich:column>
               <f:facet name="header">Descricao</f:facet>
               <h:outputText value="#{_classif.sofClassificacao.dsClassificacao}" />
          </rich:column>
          <rich:column>
               <f:facet name="header">PS-Desconto</f:facet>
               <h:outputText value="#{_classif.psDesconto}" />
          </rich:column>
          <rich:column>
               <f:facet name="header">PC-Desconto</f:facet>
               <h:outputText value="#{_classif.pcDesconto}" />
          </rich:column>
          
          <a:support event="onRowClick" action="#{classificacaoAction.setClassificacaoAtual(_classif)}" 
               reRender="classif-romaneio"  rendered="#{editarRomaneio}"/>
          
     </rich:dataTable>
</rich:tab>

When I click the button it's calling the proximaClassificacao method but the classificacaoAtual property still have the old value (looking at debug). After the reRender I can see that the old classificacaoAtual and the new classificacaoAtual, both have the value that I typed in the input text.

Any clue of what´s happening?

Thanks in advance.

Your Seam component is CONVERSATION scoped, but how are you starting the conversation (e.g., @Begin)?

Fine grained XML. But that's not the point.

I made some modifications and now it's updating it right, but another situation appeared.

The @Out classificacaoAtual property receive null value at some point as expected (proximaClassificacao() method).

But when it reaches that situation JSF is not reRendering classif-romaneio div right (it should disappear).

Some help here?
