JSF selectboolean checkbox in datatable not showing up

Question

Firstly I would provide my configuration details:
JSF - 1.2
Icefaces - 1.8
Servlet - 2.5

I am trying to put an ice:selectBooleanCheckbox in a datatable. But, I am facing an expception repeatedly:

icelogin.jspx @54,59 value="#{o.checkBox}": ELResolver cannot handle a null base Object with identifier 'o'

Here is my jspx code

            <h3>User Name and Password</h3>
            <table>
               <tr>
                  <td>
                     <ice:outputLabel value="Name"/>
                  </td>
                  <td>
                     <ice:inputText value="#{userLogin.name}"/>
                  </td>
               </tr>
               <tr>
                  <td>
                     <ice:outputLabel value="Password"/>
                  </td>
                  <td>

                  </td>
               </tr>
            </table>
            <ice:dataTable value="#{userLogin.orderList}" var="o">
               <ice:column>
                  <!-- column header -->
                  <f:facet name="header">Order No</f:facet>
                  <!-- row record -->
                  #{o.orderNo}
               </ice:column>
               <ice:column>
                  <f:facet name="header">Product Name</f:facet>
                  #{o.productName}
               </ice:column>
               <ice:column>
                  <f:facet name="header">Price</f:facet>
                  #{o.price}
               </ice:column>
               <ice:column>
                  <!-- column header -->
                  <f:facet name="header">Checkbox</f:facet>
                  <!-- row record -->
                  <ice:selectBooleanCheckbox value="#{o.checkBox}"/>
                  <!-- #{o.checkBox} --> 
               </ice:column>
               <ice:column>
                  <f:facet name="header">Quantity</f:facet>
                  #{o.qty}
               </ice:column>
            </ice:dataTable>
            <ice:commandButton type="submit"  value="Sign In" action="#userLogin.saveData}"/>
         </ice:form>
      </body>
   </f:view>
</html>

If I remove checkBox value from #{o.checkBox} to true or false, it works. I presume that for true, the checkBox should be selected in UI, and false it must remain unselected. But, even if I put code like this

<ice:selectBooleanCheckbox value="true"/>

check button is being displayed in UI but is not showing up selected though the value is true. I am following this tutorial, in my case I have one more extra parameter in my bean.

boolean checkBox;

I have getters and setters in place, and passed to the constructor, all set. What could be wrong?
