zk: after confirmation box, page refresh issue, bi

I was successfully deleting selected items from listbox and after that all objects were deleted from db and listbox was refreshed. then i added the confirmation box with yes and no option, then my list wasn't refreshed. i saw this thread with similar problem on zk forum with a solution, i implemented it but getting the class cast exception

I am using MVVM

http://forum.zkoss.org/question/73640/refreshing-listbox-after-deleting-an-itemrow/

code getting the exception:

AnnotateDataBinder binder = (AnnotateDataBinder) userWin.getAttribute("binder");
                    binder.loadAll();

exception:

Mar 21, 2013 5:22:23 PM org.zkoss.zk.ui.impl.UiEngineImpl handleError:1352
SEVERE: >>java.lang.ClassCastException: org.zkoss.bind.AnnotateBinder cannot be cast to org.zkoss.zkplus.databind.AnnotateDataBinder

looking forward to hear from you. I have searched the net, but couldn't find anything but updating the zk. i am already using the latest version of zk 6.5.1.1.

thanks in advance.

@after adding your suggested line of code, my list was not updated, here is my method

 @Override
    @Command("deleteAllSelected")
    @NotifyChange({"selectedObject","objectList"})
    public void deleteAllSelected() {
        logger.info("in deleteAllSelected()>>>>>>>>>>>>>>>>>>>>>>>>>>>>");

        logger.info("direct selection: " + objectList.getSelection());
        final Set<UserIntelliopsDTO> setMe = objectList.getSelection();
        logger.info("selectedion size in dellete all" + setMe.size());



        EventListener<ClickEvent> clickListener = new EventListener<Messagebox.ClickEvent>() {
            public void onEvent(ClickEvent event) throws Exception {
                if (Messagebox.Button.YES.equals(event.getButton())) {
                    int i =0;
                    for(UserIntelliopsDTO dto:setMe){

                        userService.deleteUserIntelliops(dto.getUserIntelliOps().getUserId());

                        logger.info("siapa:userIntelliops " + dto.getUserIntelliOps() +  dto.getUserIntelliOps().getUserId());
                        selectedObject = null;

                        logger.info("iteration: " + i);
                        ++i;
                    }

                    selectedObject = null;
                    deleteAllSelectedButton.setVisible(false);
                    enableEditMode(true);


                }
            }
        };
        Messagebox.show("Are you sure you want to delete all selected records?", "Delete All Selected",
                new Messagebox.Button[] { Messagebox.Button.YES,
                        Messagebox.Button.NO }, Messagebox.QUESTION,
                clickListener);


        BindUtils.postNotifyChange(null, null, this, "*");

    }

I am assuming you are using MVVM Model..So you can do this thing when you will click on delete button below method will code...

 @Command
public void doDeleteItems(@ContextParam(ContextType.VIEW) Component view) {
        logger.debug("Delete Icon selected");

if (myModel.getSelectedListItem() == null || myModel.getSelectedListItem().isEmpty()) {
            showError("No rows are selected");
        } else {

Messagebox.show("Are you sure you want to delete?", "Alert !!", Messagebox.YES | Messagebox.NO, Messagebox.QUESTION,new org.zkoss.zk.ui.event.EventListener() {

public void onEvent(Event evt) throws InterruptedException {
    if (evt.getName().equals("onYes")) {
//Add code for Deletion
  if (listModel.contains(deletedObj))
listModel.remove(deletedObj); 
}
else{
//Do somthing else
}
BindUtils.postNotifyChange(null, null, this, "*");//this means current viewmodel object and refresh the variables

}

As i did BindUtils.postNotifyChange() it will do magic for you refreshing the list or you can use NotifyChange("*")

One more thing you have to do here remove object from list after deleting the record...
