<a4j:commandbutton value="Modifier" ajaxSingle="true" id="editlink"
                oncomplete="#{rich:component('editPanel')}.show()" action="#{valeursMBean.viwDetail}" />

        <rich:modalPanel id="editPanel" autosized="true" width="450">
            <f:facet name="header">
                <h:outputText value="Modifier la valeur mobiliere actuelle :" />
            </f:facet>
            <f:facet name="controls">
                <h:panelGroup>
                    <h:graphicImage value="../style/close.jpeg" id="hidelink"
                        styleClass="hidelink" />
                    <rich:componentControl for="editPanel" attachTo="hidelink"
                        operation="hide" event="onclick" />
                </h:panelGroup>
            </f:facet>
            <h:form>
                <rich:messages style="color:red;"></rich:messages>
                <h:panelGrid columns="1">
                    <a4j:outputPanel ajaxRendered="true">
                        <h:panelGrid columns="2">
                            <h:outputLabel value="CodeIsin" for="codeIsin" />
                            <h:inputText id="codeIsin"
                                value="#{valeursMBean.currentItem.codeIsin}" />
                            <h:outputLabel value="Categorie" for="categorie" />
                            <h:inputText id="categorie"
                                value="#{valeursMBean.currentItem.categorie}" />
                            <h:outputLabel value="Denomination" for="denomination" />
                            <h:inputText id="denomination"
                                value="#{valeursMBean.currentItem.denomination}" />
                            <h:outputLabel value="Date Echeance" for="dateEcheance" />
                            <h:inputText id="dateEcheance"
                                value="#{valeursMBean.currentItem.dateEcheance}" />

                        </h:panelGrid>
                        <rich:message showSummary="true" showDetail="false" for="etat" />
                    </a4j:outputPanel>
                    <a4j:commandButton value="Enregistrer"
                        action="#{valeursMBean.update}"
                        reRender="codeIsin, categorie, etat, denomination, dateEcheance"
                        oncomplete="if (#{facesContext.maximumSeverity==null}) #{rich:component('editPanel')}.hide();" />
                </h:panelGrid>
            </h:form>
        </rich:modalPanel>

import cdvm.surv.model.ValeurRef;
import cdvm.surv.service.ValeurRefService;

@Component("valeursMBean")
@Scope("session")
public class ValeursMBean implements Serializable {

    @Autowired
    private transient ValeurRefService valeurefService;
    private transient HtmlScrollableDataTable valeurTable;


    private List<ValeurRef> valeurefList;
    private ValeurRef currentItem;


    @PostConstruct
    public void init(){
        valeurefList = valeurefService.find();
    }

    public String update(){
        valeurefService.save(currentItem);
        init();

        return null;
    }

    public void viewDetail(){
        List<ValeurRef> valueList=(List<ValeurRef>) valeurTable.getValue();
        Selection sl = valeurTable.getSelection();
        Iterator<Object> keys= sl.getKeys();

        if(keys.hasNext()){
            //SimpleRowKey ky = (SimpleRowKey)keys.next();
            currentItem=valueList.get((Integer)keys.next());
            System.out.println(currentItem.getCodeIsin());
        }


    }

    // Getter and Setter

    public ValeurRef getCurrentItem() {
        return currentItem;
    }

    public void setCurrentItem(ValeurRef currentItem) {
        this.currentItem = currentItem;
    }
    public HtmlScrollableDataTable getValeurTable() {
        return valeurTable;
    }
    public void setValeurTable(HtmlScrollableDataTable valeurTable) {
        this.valeurTable = valeurTable;
    }
    public List<ValeurRef> getValeurefList() {
        return valeurefList;
    }
    public void setValeurefList(List<ValeurRef> valeurefList) {
        this.valeurefList = valeurefList;
    }

}
