Question

Dear All, I have a problem about showing data to textbox. I have a class i call it itemCategoryFormController.java here the code:
public class ItemCategoryFormController extends GenericForwardComposer {
    @Autowired
    private DatabaseManager databaseManager;
    @Autowired
    private SessionManager sessionManager;
    @Autowired
    private SecurityService securityService;
    @Autowired
    private MasterService masterService;
    private WebUtil webUtil;
    private DataBinder binder;
    private Paging itemGroupPaging;
    private Combobox filterCBox;
    private Listbox itemGroupLBox;
    private Bandbox itemGroupBd;
    private Integer totalItemGroup = 0;
    private String locationPath;
    private Map<String, Object> params;
    private ItemCategory selectedItemCategory;
    private ItemCategory selectedTemp;
    private ItemGroup selectedItemGroup;
    private List<ItemCategory> itemFilters = new ArrayList<ItemCategory>();
    private List<ItemGroup> itemGroups = new ArrayList<ItemGroup>();
    public ItemCategory getSelectedItemCategory() {
        return selectedItemCategory;
    public void setSelectedItemCategory(ItemCategory selectedItemCategory) {
        this.selectedItemCategory = selectedItemCategory;
    public ItemGroup getSelectedItemGroup() {
        return selectedItemGroup;
    public void setSelectedItemGroup(ItemGroup selectedItemGroup) {
        this.selectedItemGroup = selectedItemGroup;
    public List<ItemCategory> getItemFilters() {
        return itemFilters;
    public void setItemFilters(List<ItemCategory> itemFilters) {
        this.itemFilters = itemFilters;
    public List<ItemGroup> getItemGroups() {
        return itemGroups;
    public void setItemGroups(List<ItemGroup> itemGroups) {
        this.itemGroups = itemGroups;
    @SuppressWarnings("unchecked")
    @Override
    public void doAfterCompose(Component comp) throws Exception {
        super.doAfterCompose(comp);
        this.self.setAttribute(Constants.CTRL, this, false);
        webUtil = new WebUtil(comp);
        params = (Map<String, Object>) Executions.getCurrent().getArg();
        AppProgram program = securityService.getAppProgramByUrl(sessionManager.getUrlAddress());
        locationPath = program.getFileName();
        selectedUserLogin = sessionManager.getAppUser();
        setControlPermission(program);
        binder = new AnnotateDataBinder(comp);
    public void onCreateWin(Event event) {
        if(isMessageMode()) loadMessage();         
        selectedItemCategory = (ItemCategory) params.get(Constants.PARAM_ITEMCATEGORY);
        init();
    private void init() {
        String action = (String) params.get(WebUtil.PARAM_ACTION);
        if(action.equals(WebUtil.ACTION_NEW)) {
            if(selectedItemCategory != null){
                selectedItemCategory.setActive(true);
                selectedItemCategory.setLastUpdated(databaseManager.getDateServerNow());
                selectedItemCategory.setLastUpdater(sessionManager.getAppUser().getUserId());
                selectedTemp = selectedItemCategory;
                selectedItemCategory = new ItemCategory();
            }else{
                selectedItemCategory = new ItemCategory();
                selectedItemCategory.setActive(true);
                selectedItemCategory.setLastUpdated(databaseManager.getDateServerNow());
                selectedItemCategory.setLastUpdater(sessionManager.getAppUser().getUserId());
        } else {
            if(selectedItemCategory == null) selectedItemCategory = selectedTemp;
        loadItemGroup();
        viewMode = action.equals(WebUtil.ACTION_VIEW);
        editMode = action.equals(WebUtil.ACTION_EDIT);
        if((action.equals(WebUtil.ACTION_EDIT) || action.equals(WebUtil.ACTION_VIEW))) {
            checkPrevNext();
        binder.loadAll();
    private void loadItemGroup() {
        totalItemGroup = masterService.countItemGroup();
        itemGroupPaging.setTotalSize(totalItemGroup);
        selectedItemGroup = masterService.getitemGroupByNo(selectedItemCategory.getItemCategoryGroupNo());
        itemGroups = masterService.getitemGroups(0, itemGroupPaging.getPageSize());
        doPaging(itemGroupPaging, Constants.PARAM_ITEMGROUP);
    public void onChanging$filterCBox(InputEvent event) {
        Integer sizeOfFilter = Integer.valueOf(Labels.getLabel(Constants.I3_PAGESIZE_FILTER));
        itemFilters = masterService.getitemCategorysByFilter("%" + event.getValue() + "%", 0, sizeOfFilter);
        binder.loadComponent(filterCBox);
    public void onChanging$itemGroupFilterTb(InputEvent event) {
        itemGroups = masterService.getitemGroupsByFilter("%" + event.getValue() + "%", 0, itemGroupPaging.getPageSize());
        itemGroupPaging.setTotalSize(masterService.countItemGroupByFilter("%" + event.getValue() + "%"));
        itemGroupPaging.setActivePage(0);
        binder.loadComponent(itemGroupLBox);
    @SuppressWarnings({ "unchecked" })
    private void doPaging(final Paging paging, final String param) {
        paging.addEventListener("onPaging", new EventListener() {
            @Override
            public void onEvent(Event event) throws Exception {
                PagingEvent pEvent = (PagingEvent) event;
                int pageNo = pEvent.getActivePage();
                int first = pageNo * paging.getPageSize() + 1;
                int last = first + paging.getPageSize() - 1;
                redraw(param, first, last);
    protected void redraw(String param, int first, int last) {
        if(param.equals(Constants.PARAM_ITEMGROUP)) {
            itemGroups = masterService.getitemGroups(first, last);
            binder.loadComponent(itemGroupLBox);
    public void onClick$itemGroupClearBtn(Event event) {
        selectedItemGroup = null;
        binder.loadComponent(itemGroupBd);
        itemGroupBd.close();
    private void clearForm() {
        selectedItemCategory = null;
        selectedItemGroup = null;
I have a zul file that call form.zul Here i want show itemgroups data:
<bandbox id="itemGroupBd" width="30%" onfocus="itemGroupBd.open=true" autodrop="true" readonly="true" value="@{ctrl.selectedItemGroup, converter='com.cynergy.web.converter.NameObjectConverter' }" disabled="@{ctrl.viewMode }"> <bandpopup>
<vbox>
<hbox>
<image src="/images/icons/icon-filter-16.png"/> <label value="${c:l('label.filter.value')}"/>
<textbox id="itemGroupFilterTb"/> <space width="5px"/>
<button id="itemGroupClearBtn" label="${c:l('button.clear.value')}"/>
</hbox>
<listbox id="itemGroupLBox" model="@{ctrl.itemGroups }" width="400px" onselect="itemGroupBd.close();" rows="${c:l('label.pageSize.bandbox.value')}" selecteditem="@{ctrl.selectedItemGroup }" emptymessage="${c:l('message.list.data.empty')}">
<listhead sizable="true">
<listheader width="30%" label="${c:l('label.code.value')}"/>
<listheader label="${c:l('label.name.value')}"/></listhead>
<listitem self="@{each=itemGroup }">
<listcell label="@{itemGroup.itemGroupNo }"/>
<listcell label="@{itemGroup.itemGroupName }"/>
</listitem>
</listbox>
<paging id="itemGroupPaging" detailed="true" pagesize="${c:l('label.pageSize.bandbox.value')}" sclass="paging-border"/>
</vbox>
</bandpopup>
</bandbox>
There are no error showing, but textbox not showing the data. Textbox only showing:
com.procits.app.master.model.ItemGroup@6924b697
I'm new in java programming i hope you can help me.

cvsSpecMapping is a resource and not a property so you should set the DataContext using the StaticResource markup extension instead of Binding:
<StackPanel Orientation="Horizontal" Margin="0, 5" DataContext="{StaticResource cvsSpecMapping}">
Also, the Source property of a CollectionViewSource is supposed to be set to a collection:
private void Window_Loaded(object sender, RoutedEventArgs e)
sm = new Models.SpecimenMapping();
var cvsSpecMapNames = (CollectionViewSource)(this.FindResource("cvsSpecMapping"));
cvsSpecMapNames.Source = new List<Models.SpecimenMapping>() { sm };
You may also want to set a default value of the HL7SpecimenTypeName property to confirm that the binding actually works after you have done the above changes:
public class SpecimenMapping : INotifyPropertyChanged
private const int MAX_HL7SPECIMENTYPENAME_LEN = 250;
#region class properties
private string _hl7SpecimenTypeName = "def....";
public string HL7SpecimenTypeName
get { return _hl7SpecimenTypeName; }
set
if (value != _hl7SpecimenTypeName)
_hl7SpecimenTypeName = EnforceMaxLength(value, MAX_HL7SPECIMENTYPENAME_LEN);
NotifyPropertyChanged();
Hope that helps.
