Select Item in the Grid

[snjy85]

Hello all,
I am using smart gwt2.2 on windows system, with browser Mozilla.
In smart gwt I am using a ListGrid.And in that ListGrid for one field I have set the editor type to Select Item.

SelectItem item = new  SelectItem();
ListGridField field = new ListGridField("Field", "Field");
field.setEditorType(item);

My problem is that is I set the simple string value map to the Select Item then it works fine, But while same list coming from server side and I try to set then it is giving this error,

Uncaught JavaScript exception [this.formItem is undefined] in http://127.0.0.1:8888/nextenders/sc/modules/ISC_Forms.js, line 1831

I am not getting at which place I am doing wrong.

Can you include a source code relative to your Side server side code ?
What do you want to set ?

Code for Setting Editor Type

private static NTListGridField[] getFields(
			List<FormControlMap> srcFormCtrlMapList,
			Map<String, Object> srcformCtrlMap, FormControlMap map1) {
		NTListGridField[] columns = new NTListGridField[srcFormCtrlMapList
				.size()];
		int i = 0;
		for (FormControlMap map : srcFormCtrlMapList) {
			Control control = (Control) map.getIsBean_2();
			String str = UIControlUtil.getControlName(String.valueOf(control.getId()));
			NTListGridField field = new NTListGridField(str, control.getName());
			Layout mapLayout = map.getLayout();
			if (mapLayout != null) {
				ControlType controlType = mapLayout.getControlType();
				if (controlType != null) {
					FormItem item = null;
					if (controlType.equals(ControlType.TEXTBOX)) {
						item = new NTTextItem();
					} else if (controlType.equals(ControlType.TEXTAREA)) {
						item = new NTTextAreaItem();
						item.setHeight(25);
					} else if (controlType.equals(ControlType.DATE_TIME)) {
						item = new NTDateTimeItem();
						((NTDateTimeItem) item)
								.setDisplayFormat(DateDisplayFormat.TOUSSHORTDATETIME);

					} else if (controlType.equals(ControlType.CHECK_BOX)) {
						item = new NTCheckBoxItem();
					} else if (controlType.equals(ControlType.DATE)) {
						field.setType(ListGridFieldType.DATE);
					} else if (controlType.equals(ControlType.DROPDOWN)
							|| controlType
									.equals(ControlType.MULTI_CHOICE_LIST)) {
						item = NTDropDownUtil.getDefaultDropDown(map,str,
								false, false);
					}
					if (item != null) {
						field.setEditorType(item);
					}
				}
			columns[i] = field;
			i++;
		}
		return columns;
	}
