The itemValue of the selectOneMenu Do Not Show Up in Browser

Question

I am creating a dropdown menu and users can make only one selection from the menu. I do not have compilation problem. And I am able to see a drop-down in the browser window. Except that when I click on the downward arrow of the dropdown, I see a "blank". All the itemValue that I hard coded in my JSP in the menu do not show up. What was my problem?
My JSP:
<af:form>
     <h:selectOneMenu value="#{eaGenerateWordDocHandler.supportingLevel}" style="width:50px">
          <f:selectItem itemValue="0"/>
          <f:selectItem itemValue="1"/>
          <f:selectItem itemValue="2"/>
          <f:selectItem itemValue="3"/>
          <f:selectItem itemValue="4"/>               
     </h:selectOneMenu>
</af:form>
.......EaGenerateWordDocHandler.java has the getter and the setter:
     String supportingLevel     = null;
     int level = 0;
     public int getSupportingLevel() {
          String tmpSupportingLevel = getRequest().getParameter("supportingLevel");
          if ( tmpSupportingLevel != null && !tmpSupportingLevel.equals("")){
             level = Integer.parseInt( tmpSupportingLevel );
          }else{
               level = 0;
          return level;
     public void setSupportingLevel(String supportingLevel) {
          this.supportingLevel = supportingLevel;
     }faces-config.xml:
<managed-bean>
     <managed-bean-name>eaGenerateWordDocHandler</managed-bean-name>
        <managed-bean-class>CompanyName.webapp.action.EaGenerateWordDocHandler</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
</managed-bean>

Can you try adding itemLabel attribute to f:selectItem.
<f:selectItem itemValue="0" itemLabel="0"/>
