    rich:pickLis dose not accept f:selectItems value as object

    Mohammad Weshah Novice

      Dears,

      i have a rich:picklist and inisde it f:selectItems the value for selectItems is an object of the same type of the value of rich:picklist , the problem nothing happen when i press the action button i.e(the value for the rich:pickList dose not set to the selected objects if i select any object and the action method dose not fire ) , i changed the code as the following to fire the action:

      - change rich:pickList value to the List of Integer

      - and change f:selectItems value to the List of Integer

      - and in the action methos process the intger values and populate a list of my object

       

      why the rich:pickList dose not work with f:selectItems object value not integer

       

      Regards

          you are using selectitem of jsf so its object type should be select item of list,not as integer.

           

          <a4j:region>

                                                      <rich:pickList id="pickListPanel"

                                                          copyAllControlLabel="#{messages['button.SelectAll']}"

                                                          copyControlLabel="#{messages['button.Select']}"

                                                          removeControlLabel="#{messages['button.Remove']}"

                                                          removeAllControlLabel="#{messages['button.RemoveAll']}"

                                                          moveControlsVerticalAlign="middle" listsHeight="400px"

                                                          style="marigin-left:-2px;" sourceListWidth="250px"

                                                          targetListWidth="250px"

                                                          value="#{updateAttendanceHome.empAttendanceList}">

                                                         <f:selectItems

                                                              value="#{updateAttendanceHome.empNominatedList}" />

                                                          <a4j:support event="onlistchanged" ajaxSingle="true" />

                                                      </rich:pickList>

                                                      <rich:message id="picklist" for="pickListPanel">

                                                      </rich:message>

                                                  </a4j:region>

           

           

           

           

          public List<SelectItem> getNominatedEmployeeList() {

                

          ----------------------------------------- UR code -----------------------

           

                  Employee emp;

                  String name;

                  Long eid;

           

                  while (updatedGapIte.hasNext()) {

                      trainingplanhistory = updatedGapIte.next();

                      emp = trainingplanhistory.getEmployee();

                      name = emp.getName();

                      eid = emp.getEid();

           

                      SelectItem val = new SelectItem(name + " - " + eid);

                      empNominatedList.add(val);

                  }

                 setEmpNominatedList(empNominatedList);

                  return empNominatedList;

              }

           

          Sure it will load the data in the picklist and works fine........

            i know if i add value as primitive it will works but in my case the value it should be Object of my bean , i think i ahve to do it with converter .

              Please have a look on here for <f:selectItems>,

               

              http://stackoverflow.com/tags/selectonemenu/info

               

              you can also use like below if you use s:selectItems,It depends on your project setup and implementation

               

              converter="#{employeeIdConvertor}"> 









              <s:selectItems value="#{participantGroupEmployeeMappingHome.empList}" var="empName"










              label="#{empName.name} - #{empName.eid}"/>

               

              /**

                   * @param empList the empList to set

                   */

                  public void setEmpList(List<Employee> empList) {

                      this.empList = empList;

                  }

               

               

                  /**

                   * @return the empList

                   */

                  public List<Employee> getEmpList() {

                      return empList;

                  }

               

              Convertor like:

               

              public Object getAsObject(FacesContext arg0, UIComponent arg1, String value)

                  {

                      // TODO Auto-generated method stub

                      Long conversionString = Long.parseLong(value);       

                      return mapValue.get(conversionString);                

                  }

               

                  public String getAsString(FacesContext arg0, UIComponent arg1, Object value)

                  {

                      // TODO Auto-generated method stub

                      mapValue.put(((Employee) value).getEid(), (Employee) value);

                      return ((Employee) value).getEid().toString();          

                  }

               

              You can alos use seam convert entity by default,

               

              <s:selectItems value="#{emptrainingrolemappingHome.trainingRolesSelectItemList}" var="role"

                                                      label="#{role.trainrolename}"/>       

                                                      <s:convertEntity></s:convertEntity>

                Yes, a converter is required for the picklist to work with Objects.
