Tengo una aplicación donde tengo un menú desplegable en cascada, un menú desplegable simple y un botón de comando de envío. Deseo mostrar el informe en datos seleccionando varios criterios de los desplegables. todo funciona bien, excepto cuando deseo seleccionar los criterios del menú desplegable de niños. no se enlaza con su valor en el bean administrado (se encontró que al depurar). Aquí está mi código: xhtml:

<h:outputText value="Exchange"/>
            <p:selectOneMenu style="width: 150px" value="#{reportBean.exchange}">
                <f:selectItem itemLabel="--select--" itemValue="--select--"/>
                <f:selectItem itemLabel="NSE" itemValue="nse"/>
                <f:selectItem itemLabel="BSE" itemValue="bse"/> 
                <p:ajax update="sym" listener="#{reportBean.wow}"/>
            </p:selectOneMenu>             
        <h:outputText value="Scrip Symbol :"/>
        <p:selectOneMenu value="#{reportBean.scripID}" id="sym" style="width: 100px">
            <f:selectItem itemLabel="All" itemValue="0"/>
            <f:selectItems var="scrip" value="#{reportBean.sl}" itemLabel="#{scrip.scripSymbol}" itemValue="#{scrip.scripID}"/>
        </p:selectOneMenu>

        <h:outputText value="Order Type :"/>
        <p:selectOneMenu style="width: 100px" value="#{reportBean.orderType}">
            <f:selectItem itemLabel="All" itemValue="All"/>
            <f:selectItem itemLabel="Buy" itemValue="B"/>
            <f:selectItem itemLabel="Sell" itemValue="S"/>
        </p:selectOneMenu>
            <p:commandButton ajax="true" update="dt" value="Submit" action="#{reportBean.getTradeByUserName()}" type="submit"/>
        </h:panelGrid>
        <p:dataTable id="dt" var="trade" widgetVar="scripTab" 
                     emptyMessage="No trade found with given criteria"  
                     value="#{reportBean.tradeList}"
                 paginator="true" paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink}"
                 rowsPerPageTemplate="3,5,10" rows="3" >


        <p:column>....

código bean gestionado:

    public void wow()
{    
        sl=getAllScripByExchange(exchange);
}

    public Integer getScripID() {
        return scripID;
    }

    public void setScripID(Integer scripID) {
        MasterScrip sm =getScripByID(scripID);
        if(sm!=null)
        this.scripSymbol=sm.getScripSymbol();
        this.scripID = scripID;
    }

    public List<TradeStock> getTradeList() {
        return tradeList;
    }

    public void setTradeList(List<TradeStock> tradeList) {
        this.tradeList = tradeList;
    }
     public List<service.TradeStock> getTradeByUserName()
    {
         HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
        HttpSession session = request.getSession(true);
        String uname = session.getAttribute("uname").toString();   
        tradeList= getTradeReport(scripID, uname, exchange, orderType);
        return tradeList;
    }

método de frijol

@Override
public Collection<TradeStock> getTradeReport(Integer scripID, String uname, String exchange, String tradeType) {

    String strQuery = null;
    strQuery = "Select t from TradeStock t where t.userName.userName = :userName ";
        if(! exchange.equalsIgnoreCase("All"))
    {
        strQuery += " and t.scripID.exchange = '" + exchange + "'";
    }         
    if(scripID>0)
    {
        strQuery += " and t.scripID.scripID = " + scripID;
    }
     if(! tradeType.equalsIgnoreCase("All"))
    {
        strQuery += " and t.orderID.buySell = '" + tradeType + "'";
    }

    Collection<TradeStock> c = em.createQuery(strQuery).setParameter("userName",uname).getResultList();

    return c;
}

¿Por qué el valor no se une a los apoyos de frijol? ¿Cómo lo resuelvo? (lo que me preocupa es que el mismo código funcionó ayer, pero hoy cuando lo ejecuté, empecé a preocuparme).
