    How to refresh an ice:selectManyListbox

    Ouertani Ahmed Newbie

      I need to build a pick list,  I used two [b]ice:selectManyListbox [/b] and two button "left" "right". My problem is, when I pass list item from left to right that I find myself obliged to refresh the page to see the change.

      Is that it is possible to see the changes without refreshing the page ?

      Help me please.

       

      The pick list code :

       

      [code]

       

      <ice:selectManyListbox size="10" style="width: 150px;"  valueChangeListener="#{EventForm.toRightListener}"

                                      rendered="true" partialSubmit="true" value="#{EventForm.selectedLeftContact}">

                                      <s:selectItems value="#{contactLeftList}"

                                          var="contact" label="#{contact.name}" />

                                      <s:convertEntity />

                                  </ice:selectManyListbox>

       

                                  <ice:panelGrid columns="1">

       

       

                                      <ice:commandButton value=" &gt; "

                                          action="#{EventForm.toRight}" />

                                      <ice:commandButton value=" &lt; " action="#{EventForm.toLeft}" />

       

                                  </ice:panelGrid>

       

       

       

       

                                  <ice:selectManyListbox size="10" style="width: 150px;" valueChangeListener="#{EventForm.toRightListener}"

                                      rendered="true" partialSubmit="true"

                                      value="#{EventForm.selectedRightContact}">

                                      <s:selectItems value="#{EventForm.contactRightList}"

                                          var="contact" label="#{contact.name}" />

                                      <s:convertEntity />

                                  </ice:selectManyListbox>

       

                                  <ice:commandButton value=" Sort left column"

                                      action="#{EventForm.sortLeft()}" />

                                  <ice:panelGroup></ice:panelGroup>

                                  <ice:commandButton value=" Sort right column"

                                      action="#{EventForm.sortRight()}" />

       

                              </ice:panelGrid>

       

      [/code]

       

      The managed bean code :

       

      [code]

      List<Contact> contactLeftList = new  ArrayList<Contact>();

       

          private List<Contact> selectedLeftContact = new  ArrayList<Contact>(); 

       

       

          private List<Contact> selectedRightContact = new  ArrayList<Contact>();

         

         

          private List<Contact> contactRightList = new  ArrayList<Contact>();

       

       

       

         

          @Factory("contactLeftList")

          public List<Contact> initContactLeftList() {

       

              contactLeftList = em

              .createQuery("select contact from Contact contact")

              .getResultList();

             

              return contactLeftList;

          }

             

         

          public void toRight() {

             

              Iterator<Contact> selected = selectedLeftContact.iterator();

              while (selected.hasNext()) {

       

                  Object o;

                  Object item = selected.next();

       

                  Iterator<Contact> iterator = contactLeftList.iterator();

                  while (iterator.hasNext()) {

                      o = iterator.next();

                      if (((Contact) o).equals(item)) {

                          contactLeftList.remove(o);

                          contactRightList.add((Contact) o);

                          break;

                      }

                  }

              }

       

              selectedLeftContact = null;

       

          }

       

          public void toLeft() {

       

              Iterator<Contact> selected = selectedRightContact.iterator();

              while (selected.hasNext()) {

       

                  Object o;

                  Object item =  selected.next();

       

                  Iterator<Contact> iterator = contactRightList.iterator();

                  while (iterator.hasNext()) {

                      o = iterator.next();

                      if (((Contact) o).equals(item)) {

                          contactRightList.remove(o);

                          contactLeftList.add((Contact) o);

                          break;

                      }

                  }

              }

       

              selectedRightContact = null;

       

          }

      [/code]
