datatableRowSelectionByColumn primefaces

Front-end

e ai gente.
estou querendo fazer que nem o ShowCase mostra http://www.primefaces.org/showcase/ui/datatableRowSelectionByColumn.jsf , mostrar detalhes em uma dialog
mas não funciona, só mostra os textos, e não o conteúdo, meus códigos:
DocumentoMB:


package managedBeans;

@ManagedBean(name = "documentoMB")
@SessionScoped
public class DocumentoMB implements Serializable {
    
    private Documento documento;
    @EJB
    private DocumentoFacade documentoFacade;
         
    public DocumentoMB() {
    }

    public Documento getDocumento() {
        return documento;
    }

    public void setDocumento(Documento documento) {
        this.documento = documento;
    }
    

    public Documento getSelected() {
        if (documento == null) {
            documento = new Documento();
            selectedItemIndex = -1;
        }
        return documento;
    }

    private DocumentoFacade getFacade() {
        return documentoFacade;
    }

}

claro que tem mais coisas

e minha tela:


   <p:dataTable value="#{documentoMB.items}" var="item" id="tabela">                  
		  <p:column style="width:40px"> 
                        <f:facet name="header">
                            <h:outputText value="Detalhes"/>
                        </f:facet>
                            <p:commandButton id="selectButton" oncomplete="itemDialog.show()" icon="ui-icon-search" title="View">  
                                <f:setPropertyActionListener value="#{item}" target="#{documentoMB.documento}"/>  
                            </p:commandButton>                          
                    </p:column> 
                </p:dataTable>

                <p:dialog header="Detalhes do Documento" widgetVar="itemDialog" resizable="false" id="carDlg"  
                          showEffect="fade" modal="true">  

                    <h:panelGrid id="display" columns="2" cellpadding="4" style="margin:0 auto;">  
                        <h:outputText value="#{bundle.DocumentoLabel_ano}"/>
                        <h:outputText value="#{documentoMB.selected.ano}" title="#{bundle.DocumentoTitle_ano}"/>
                        <h:outputText value="#{bundle.DocumentoLabel_titulo}"/>
                        <h:outputText value="#{documentoMB.selected.titulo}" title="#{bundle.DocumentoTitle_titulo}"/>
                        <h:outputText value="#{bundle.DocumentoLabel_instituicao}"/>
                        <h:outputText value="#{documentoMB.selected.instituicao}" title="#{bundle.DocumentoTitle_instituicao}"/>
                        <h:outputText value="#{bundle.DocumentoLabel_curso}"/>
                        <h:outputText value="#{documentoMB.selected.curso}" title="#{bundle.DocumentoTitle_curso}"/>
                        
                    </h:panelGrid>  

                </p:dialog>

sempre que eu clico no botão detalhes não mostra nada no dialog, e de vez uma vez eu consegui, porém mostrava os detalhes só de um, caso escolhe-se outro, ele mostrava o mesmo selecionado por primeiro.
acho que deu para entender

#2

Cara, no dialog vc usa o objeto #{documentoMB.selected.ano}

mas na hora passar o valor vc usa: target="#{documentoMB.documento}"

Nao seria isso nao?

#3

Eita, ignora oq eu falei acima.

Esse povo ta dentro de um form?

Faltou você dar update nesse form, ou entao, coloca um form no dialog e da update nesse dialog.

#4

cara quando eu faço isso:

[code]
<p:column style=“width:40px”>
<f:facet name=“header”>
<h:outputText value=“Detalhes” />
</f:facet>

                    <h:panelGrid columns="3" styleClass="actions" cellpadding="2">  
                        <p:commandButton id="selectButton"  oncomplete="itemDialog.show()" icon="ui-icon-search" title="View">  
                            <f:setPropertyActionListener value="#{item}" target="#{documentoMB.documento}" />  
                        </p:commandButton>  
                    </h:panelGrid>

</p:column>[/code]
ele mostra o dialog mas não mostra os detalhes, só os textos.

quando eu faço isso:

 <p:commandButton id="selectButton" update=":form:display" oncomplete="itemDialog.show()" icon="ui-icon-search" title="View">

desaparece o botão
