MeasuringUnitsDS measuringUnitsDS= MeasuringUnitsDS.getInstance();
SelectItem item = new SelectItem("measuringUnitsDTO.measuringUnitsId","measuringUnitsId");
item.setWidth(240);
item.setOptionDataSource(measuringUnitsDS);
item.setValueField("measuringUnitsDTO.measuringUnitsId");
item.setDisplayField("measuringUnitsDTO.measuringUnitsId");
