How to make Partial Trigger work for a SelectManyShuttle

Question

Hi,
I'm developing a page for user role management. For each role, one or more menus could be assigned to it. We have 3 db table, Role, Menu and RoleMenu. RoleMenu is the intersection table.
At UI level, I placed one editable table on the top of a page, and put a SelectManyShuttle below the table.
I developed a backing bean for the SelectManyShuttle to get all menus and selectedMenus for the current row in the table.
The Shuttle can display selectedMenu for the first row of the Role table, but it can't update when I select another row. It seems the partial trigger is not working.
Below are the codes:
  <af:selectManyShuttle value="#{ pageFlowScope.RoleManagementBean.selectedValues}"
                leadingDescShown="true" size="8"
                              trailingDescShown="true"
                              inlineStyle="background-color:transparent; width:100%;"
                                      binding="#{pageFlowScope.RoleManagementBean.menuSelectShuttle}">
                  <f:selectItems value="#{ pageFlowScope.RoleManagementBean.allItems}"/>
  </af:selectManyShuttle>
* Implements the basic backing-bean mechanics to handle page with shuttle.
* By injecting managed properties into the properties of this bean
* you can setup the shuttle data binding declaratively.
public class RoleManagementBean {
    String beanName = "RoleManagementBean";
    String allItemsIteratorName;
    String allItemsValueAttrName;
    String allItemsDisplayAttrName;
    String allItemsDescriptionAttrName;
    String selectedValuesIteratorName;
    String selectedValuesValueAttrName;
    List selectedValues;
    List allItems;
    private boolean refreshSelectedList = false;
    private RichSelectManyShuttle menuSelectShuttle;
    public RoleManagementBean() {
    private OperationBinding findOperationBinding(String pOperationBindingName) {
        BindingContainer bindings = ADFUtils.getBindingContainer();
        OperationBinding operation =
            bindings.getOperationBinding(pOperationBindingName);
        return operation;
     * Setter for 'allItemsIteratorName' property.
     * @param allItemsIteratorName Name of the iterator for all items in the list
    public void setAllItemsIteratorName(String allItemsIteratorName) {
        this.allItemsIteratorName = allItemsIteratorName;
     * Getter for 'allItemsIteratorName' property.
     * @return Name of the iterator to use for all items in the list
    public String getAllItemsIteratorName() {
        return allItemsIteratorName;
     * Set allItems value attribute name.
     * @param allItemsValueAttrName name of attr to use as value of all items list
    public void setAllItemsValueAttrName(String allItemsValueAttrName) {
        this.allItemsValueAttrName = allItemsValueAttrName;
     * Get allItems value attribute name.
     * @return name of attr to use as value of all items list
    public String getAllItemsValueAttrName() {
        return allItemsValueAttrName;
     * Setter for 'allItemsDisplayAttrName' property.
     * @param allItemsDisplayAttrName attr to use for display in all items list
    public void setAllItemsDisplayAttrName(String allItemsDisplayAttrName) {
        this.allItemsDisplayAttrName = allItemsDisplayAttrName;
     * Getter for 'allItemsDisplayAttrName' property.
     * @return attr to use for display in all items list
    public String getAllItemsDisplayAttrName() {
        return allItemsDisplayAttrName;
     * Setter for 'allItemsDescriptionAttrName' property.
     * @param allItemsDescriptionAttrName attrib for description in all items list
    public void setAllItemsDescriptionAttrName(String allItemsDescriptionAttrName) {
        this.allItemsDescriptionAttrName = allItemsDescriptionAttrName;
     * Getter for 'allItemsDescriptionAttrName' property.
     * @return attrib for description in all items list
    public String getAllItemsDescriptionAttrName() {
        return allItemsDescriptionAttrName;
     * Setter for 'selectedValuesIteratorName' property.
     * @param selectedValuesIteratorName name of iterator for selected values
    public void setSelectedValuesIteratorName(String selectedValuesIteratorName) {
        this.selectedValuesIteratorName = selectedValuesIteratorName;
     * Getter for 'selectedValuesIteratorName' property.
     * @return name of iterator for selected values
    public String getSelectedValuesIteratorName() {
        return selectedValuesIteratorName;
     * Setter for 'selectedValuesValueAttrName' property.
     * @param selectedValuesValueAttrName name of attr to use for selected value
    public void setSelectedValuesValueAttrName(String selectedValuesValueAttrName) {
        this.selectedValuesValueAttrName = selectedValuesValueAttrName;
     * Getter for 'selectedValuesValueAttrName' property.
     * @return name of attr to use for selected value
    public String getSelectedValuesValueAttrName() {
        return selectedValuesValueAttrName;
     * Setter for 'selectedValues' property.
     * @param selectedValues List of selected values in shuttle
    public void setSelectedValues(List selectedValues) {
        this.selectedValues = selectedValues;
     * Event handler for shuttle value change event.
     * @param event value change event
    public void refreshSelectedList(ValueChangeEvent event) {
        refreshSelectedList = true;
     * Getter for 'selectedValues' property.
     * @return List of selected values in shuttle
    public List getSelectedValues() {
        if (selectedValues == null || refreshSelectedList) {
            System.out.println("here");
            selectedValues =
                    ADFUtils.attributeListForIterator(selectedValuesIteratorName,
                                                      selectedValuesValueAttrName);
        return selectedValues;
     * Setter for 'allItems' property.
     * @param allItems list of SelectItem representing all items in available list
    public void setAllItems(List allItems) {
        this.allItems = allItems;
     * Getter for 'allItems' property.
     * @return list of SelectItem representing all items in available list
    public List getAllItems() {
        if (allItems == null) {
            allItems =
                    ADFUtils.selectItemsForIterator(allItemsIteratorName, allItemsValueAttrName,
                                                    allItemsDisplayAttrName,
                                                    allItemsDescriptionAttrName);
        return allItems;
    public void setMenuSelectShuttle(RichSelectManyShuttle menuSelectShuttle) {
        this.menuSelectShuttle = menuSelectShuttle;
    public RichSelectManyShuttle getMenuSelectShuttle() {
        return menuSelectShuttle;
}I guess the partial trigger is not working because the binding of the shuttle is not relative to the binding of the role table.
any help will be appreciated!
thanks!

My problem is solved, after I removed the if statement at the backing bean getSelectedValues() method
public List getSelectedValues() {
    //    if (selectedValues == null || refreshSelectedList) {
   //         System.out.println("here");
            selectedValues =
                    ADFUtils.attributeListForIterator(selectedValuesIteratorName,
                                                      selectedValuesValueAttrName);
        return selectedValues;
    }
