JSF problem with h:selectOneMenu

Question

Hi Friends,
First of all i would like to thank u all for ur previous valuable suggestions. I got stucked up with a problem.
I have a dropdown list in which i have only 2 values 'Remodeling' and 'New'. When the user selects the option 'Remodeling' , i need to render a group of checkboxes.I tried lot many ways but didn't work.
Could anyone plz help me out on this. Below is my sample code:
Code to display drop down list
<h:selectOneMenu value="#{gfmCoverageABean.constructionType}" valueChangeListener="#gfmCoverageABean.onConstructionTypeChange}">
<f:selectItems id="typeOfConstructionProject" value="#{gfmCoverageABean.typeOfConstructionProjectList}" />
</h:selectOneMenu>
Code to render checkbox when drop down option selected is 'Remodeling'
<h:outputLabel id="foundationLbl" for="foundation" value="#{PolicyLabels['GfmCoverageADetails.Foundation']}"
rendered="#{gfmCoverageABean.constructionType eq 'Remodeling'}"/>
<ig:checkBox id="foundation" value="#{gfmCoverageABean.gfmCoverageView.foundation}"
rendered="#{gfmCoverageABean.constructionType eq 'Remodeling'}"/>
Problem here is my checkbox is not getting displayed on any case.
Thanks

Hello Vijay
Displaying group of Checkboxes
Use Value Change Listener and Create and panel Grid and render it to false
in SelectOneMenu when the value is change it calls valueChangeListener
there u check the event value if it is ur choice render panel grid to true simple.
<h:selectOneMenu value="#{Bean.selectedCategories}"
          valueChangeListener="#{Bean.processValueChange}" onchange="this.form.submit();">
               <f:attribute name="optionClasses" value="option1, option2" />
               <f:selectItem itemLabel="Please select Industry" />
               <f:selectItems value="#{Bean.selectCategories}" />
          </h:selectOneMenu>
<h:panelGrid id="chkBox" binding="#{Bean.panel}" rendered="false">
private HtmlPanelGrid panel = new HtmlPanelGrid();
///generate setter and getter
public void processValueChange(ValueChangeEvent ae) throws Exception
          if(ae.getNewValue().equals("URChoice")){          
getPanel().setRendered(true);
This will solve the problem
