      Hi Friends,

                     I had problem in <h:selectonemenu> ,

      steps to arise,

      1.Deploy webapplication

       

      2.In jsp page ,

       

      <h:form id="sampleFormId" binding="#{Sample.initForm}">

      <a4j:outputpanel id="countryOutPutPanelId">

      <h:panelGrid columns="2">

      <h:outputText value="Country:"/>

      <h:selectOneMenu value="#{Sample.country}" 

                                    id="countryId"

                                     styleClass="commonDropDownListBox">

              <f:selectItems value="#{Sample.countryItemList}"/>

               <a4j:support action="#{Sample.countryComboBoxAction}"

                                   event="onchange"                                                

                                 />

      </h:selectOneMenu>

      </h:panelGrid>

      </a4j:outputpanel>

      </h:form>

       

      3.In Sample.java

       

      private SelectItem countrySelectItem;

      private HtmlForm initForm;//(Getter setter applicable)

      private String country;//(Getter setter applicable)

      private List<SelectItem> countryItemList = new ArrayList<SelectItem>();//(Getter setter applicable)

       

      private void addingCountryItemList()

      {

           countryItemList.add(new SelectItem("India"));

             countryItemList.add(new SelectItem("Malaysia"));

             countryItemList.add(new SelectItem("China"));

      }

       

      /**

           *  countryComboBoxAction when change the selectitems

           */

      public String countryComboBoxAction()

      {

           countryItemList.remove(countrySelectItem);

      }

       

       

      /**

           * @return the initForm

           */

          public HtmlForm getInitForm()

          {

                countrySelectItem = -------------Select Country---------------------;

              countryItemList.clear();

              addingCountryItemList();

                if(!countryItemList.contains(countrySelectItem))

                {

                     countryItemList.add(0,countrySelectItem);

                }

       

                //We need to display as its first so

                country = countrySelectItem.getValue.toString();

       

                   return initForm;

          }

       

          /**

           * @param initForm the initForm to set

           */

          public void setInitForm(HtmlForm initForm)

          {

              this.initForm = initForm;

          }
