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:outputLabel value="Etat" for="etat" />
<h:inputText id="etat" value="#{valeursMBean.currentItem.etat}"/>
</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>
