Command Buttons in DataTable

Question

Hello ,
I have a page which searches all my clients accrding to some criteria, and results are shown in a table(see code bellow please ) for each row I have one CommandButton which in theory should navigate to another page , and edit the details of each client .
<h:form>
<rich:dataTable id="prospectoTable" value="#{SearchProspecto.prospectoItems}"
                var="prospecto" rowKeyVar="index"
                onRowMouseOver="this.style.backgroundColor='#FFE4E1'"
                onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'" >
    <h:column>
        <f:facet name="header">
            <h:outputText  value="#" />
        </f:facet>
        <h:outputText value="#{index+1}" />
    </h:column>
    <h:column>
        <f:facet name="header">
            <h:outputText  value="Identificacion" />
        </f:facet>
        <h:outputText value="#{prospecto.identificacion}" />
    </h:column>
    <h:column>
        <f:facet name="header">
            <h:outputText  value="Id Alterna" />
        </f:facet>
        <h:outputText value="#{prospecto.idAlterna}" />
    </h:column>
    <h:column>
        <f:facet name="header">
            <h:outputText  value="Nombre" />
        </f:facet>           
        <h:outputText value="#{prospecto.fullName}" />
    </h:column>
    <h:column>
        <f:facet name="header">
            <h:outputText  value="Estado" />
        </f:facet>           
        <h:outputText value="#{prospecto.status}" />
    </h:column>
    <h:column>
            <h:commandButton immediate="true" value="Editar" action="#{SearchProspecto.editar}"  >
                <f:setPropertyActionListener value="#{prospecto.id}" target="#{SearchProspecto.prospectoIdSelected}" />               
            </h:commandButton>
    </h:column>
    <%--
    <rich:componentControl  event="onRowDblClick" for="propectoDetails" operation="show">
        <f:param value="#{prospecto.id}" name="prospectoId" />
    </rich:componentControl>
    --%>
</rich:dataTable>
</h:form>The issue I have right now it is that backing bean code, gets called but navigation does not occur:
This is my backing bean code:
public String editar() throws NamingException, SQLException {
        System.out.println("prospecto_id="+prospectoIdSelected);
        Prospecto prospecto = Prospecto.getProspectoById(prospectoIdSelected);
        FacesUtil.setRequestMapValue("prospecto", prospecto);
        if (prospecto.getTipoCliente() == 1) {
            System.out.println("editar_empresarial");
            return "editar_empresarial";
        } else {
            System.out.println("editar_individual");
            return "editar_individual";
    }and my navigation rules in faces-config.xml:
<navigation-rule>
        <from-view-id>/Prospectacion/searchProspecto.jsp</from-view-id>
        <navigation-case>
            <from-outcome>editar_empresarial</from-outcome>
            <to-view-id>/Prospectacion/editProspecto_e.jsp</to-view-id>           
        </navigation-case>
        <navigation-case>
            <from-outcome>editar_individual</from-outcome>
            <to-view-id>/Prospectacion/editProspecto_i.jsp</to-view-id>
        </navigation-case>
    </navigation-rule>So my question is :
*1. Is it a bug ? why navigation does not occur ( action method gets invoked though) ?*
*2. I have to keep the bean in session scope , if use request scope, commadButton wont work (even action method wont be invoked) Why ? I have seen in old post ..this is a bug...but I am using SUN JSF Implementation 1.2 ....Does it still persist ?* since search could be very big...I dont want to save that in session
My software is :
JBOSS 4.2.2GA
JSF 1.2
JDK 1.6

A new request means new initial data. In case of datatables, make sure that the datamodel is exactly the same in the next request. Otherwise move the datamodel to a session scoped bean and inject it in the request scoped bean.
