confirmDialog with data from SelectOneMenu - jsf

Question

I want to show the data selected previously (from p:selectOneMenu) by user before to submit.
i use "p:SelectOneMenu", when i click Submit i have the values in the "#Postconstruct method".
<h:form>
<h:panelGrid id="grid" columns="2">
<p:selectOneMenu id="atmo" value="#{selectOneMenuView.ac_mo}"
required="true" style="width:125px">
<p:ajax listener="#{selectOneMenuView.verif_acmo}"/>
<f:selectItem itemLabel="Select One" itemValue="nothing" />
<f:selectItem itemLabel="Yes" itemValue="Yes" />
<f:selectItem itemLabel="No" itemValue="No" />
</p:selectOneMenu>
<p:selectOneMenu id="nb" value="#{selectOneMenuView.bless}" converter="nbConverter"
panelStyle="width:80%" effect="fade" required="true"
var="b" style="width:720px" filter="true" filterMatchMode="contains">
<f:selectItem itemLabel="Bless ..." itemValue="#{null}" />
<f:selectItems value="#{selectOneMenuView.blessures}" var="bless"
itemLabel="#{bless.code_nb} || #{bless.libelle_nb}" itemValue="#{bless}"/>
<p:column style="width:10%">
<h:outputText value="#{b.code_nb}" />
</p:column>
<p:column>
<h:outputText value="#{b.libelle_nb}" />
</p:column>
</p:selectOneMenu>
</h:panelGrid>
<p:commandButton value="Submit" actionListener="#{selectOneMenuView.btn}" update="grid growl"
style="margin-left:25px" icon="ui-icon-check" oncomplete="PF('confirmDlg').show()">
<p:confirm header="Confirmation" message="Are you sure ?" icon="ui-icon-alert" />
</p:commandButton>
<p:confirmDialog global="true" showEffect="fade" hideEffect="fade" widgetVar="confirmDlg" >
<p:outputLabel value="value N1 : #{selectOneMenuView.ac_mo}"/>
<p:outputLabel value="value N2 : #{selectOneMenuView.bless.libelle_nb}"/>
<p:commandButton value="Confirm" type="button" styleClass="ui-confirmdialog-yes" icon="ui-icon-check" />
<p:commandButton value="Cancel" type="button" styleClass="ui-confirmdialog-no" icon="ui-icon-close" />
</p:confirmDialog>
</p:panel>
</h:form>
i'm working with "#RequestScoped" from "javax.faces.bean.RequestScoped" in my managedbean.
NB : after validation (submit) i have the right values. so setters and getters works perfectly
NB 2 : same problem with "#ViewScoped" and "#SessionScoped"
this is the code of managedbean
#ManagedBean
#SessionScoped
public class SelectOneMenuView {
// ---- begin : ac mo
private String ac_mo;
// Getter and Setter of ac_mo
// ---- end : ac mo
// ----- Begin Blessure
private Nb bless;
private List<Nb> blessures;
#ManagedProperty("#{blessureBean}")
private NbBean nbbean;
// getters and setters of Blessure's elements
// ----- end Blessure
// ------ begin : postconstruct
#PostConstruct
public void init() {
blessures = nbbean.getBlessures();
this.ac_mo = "nothing";
}
// ------ end of postconstruct
public void btn()
{
// some stuff
}
}

Answer 1

How will that work with a request scoped bean? Please change your bean to view scoped so that the data is retained between requests.

Answer 2

solved with this :
<p:selectOneMenu>
... do something ...
<p:ajax event="change" update="confirmdialog" />
</p:selectonemenu>
