Data Table - invalid Unique Id [66000-138] while inspecting CFL SelectedObjects

[AlexMan]

After migrating customer's servers from SAP9.3 PL12 to SAP 10 2402 (through 2208) our addon started giving back an exception when accessing any property of SelectedObjects from ChooseFromListEvent

System.Runtime.InteropServices.COMException (0xFFFFE1B3): Data Table - invalid Unique Id  [66000-138]
   bei SAPbouiCOM.DataTableClass.get_IsEmpty()

on line where I use cflEvent.SelectedObjects.IsEmpty, like in code sample:

public bool ProcessItemEvent(string FormUID, ref SAPbouiCOM.ItemEvent pVal)
{
	if (pVal.EventType == SAPbouiCOM.BoEventTypes.et_CHOOSE_FROM_LIST && !pVal.BeforeAction && pVal.ActionSuccess && pVal.ItemUID == "edBP") {
		var oForm = GetForm(FormUID);

		SAPbouiCOM.ChooseFromListEvent cflEvent = pVal as SAPbouiCOM.ChooseFromListEvent;
		SAPbouiCOM.Grid grid = SAPUtils.GetControl<SAPbouiCOM.Grid>(oForm, "gRLZ");
			

		if (!cflEvent.SelectedObjects.IsEmpty)
		{
			SetCardName(oForm, cflEvent.SelectedObjects.GetValue("CardName", 0).ToString());

 Dear experts, any ideas what should I do with this? It looks like a bug.
