    ValueChangeLister error

    Thando Madida Newbie
      Hi

      I'm hoping someone can assist, I'm having problems with valueChangeListener, I am trying to set the value of total when newAreaSm changes

      In my bean buildingPlanFeesCalculationHome i have -

      @In Map<Double, UIComponent> UIComponent;
           public void updateFeeValuesChanged(ValueChangeEvent event) {
      //          JOptionPane.showMessageDialog(null, event.getSource());
                System.out.println("A value has changed!");
                double newAreaSM = ((Double) event.getNewValue()).doubleValue();
                UIComponent total = event.getComponent().findComponent("buildingPlanFeesCalculation:totalField:total");
                ((EditableValueHolder)total).setSubmittedValue(5.0);
      //          FacesContext.getCurrentInstance().renderResponse();
           }


      and in buildingPlanFeesCalculationEdit.xhtml i have -

      <h:form id="buildingPlanFeesCalculation" styleClass="edit">

      <table>
         <s:decorate id="newAreaSmField" template="/layout/edit.xhtml">
            <ui:define name="label">New area square meters</ui:define>
            <h:inputText id="newAreaSm"
               value="#{buildingPlanFeesCalculationHome.instance.newAreaSm}"
               valueChangeListener="#{buildingPlanFeesCalculationHome.updateFeeValuesChanged}">
               <a:support event="onblur" reRender="newAreaSmField,totalField" bypassUpdates="true" ajaxSingle="true"/>
            </h:inputText>
         </s:decorate>

         <s:decorate id="totalField" template="/layout/edit.xhtml">
           <ui:define name="label">Total Calculated Fees</ui:define>
           R<h:inputText id="total"
               value="#{buildingPlanFeesCalculationHome.instance.total}">
               <a:support event="onblur" reRender="totalField" bypassUpdates="true" ajaxSingle="true"/>
           </h:inputText>
         </s:decorate>

      </h:form>

      The error I'm getting is -
