如何获取DualListField中的选定项目？

Question

i don't have any idea on how to get the selected items in a DualListField. Can somebody help me. so here's my code on DualListField. And I want txtCat to be the container of the selected items aside from the TextCell. And also I want the selected item to be converted on its IDCategory

final DualListField<Category, String> field = new DualListField<Category, String>(category, toCategory, catProp.strName(), txCell);
        field.addValidator(new EmptyValidator<List<Category>>());
        field.setEnableDnd(true);
        field.setMode(Mode.INSERT);
        vlc.add(new FieldLabel(field, "Categories"), new VerticalLayoutData(1, -1, new Margins(10)));

        txtCat = new TextField();
        txtCat.setEmptyText("Value");
        txtCat.addFocusHandler(new FocusEvent.FocusHandler() {

            @Override
            public void onFocus(FocusEvent event) {
                field.getFromStore();
            }
        });
        vlc.add(new FieldLabel(txtCat, "Chosen Categories"), new VerticalLayoutData(-18, -1, new Margins(10)));

In latest GXT3 version DualListField , You could get the selected items in ToView part through field.getValue() method. You get all the data in ToView as follows. field.getToView() .getStore().getAll() . hth
