SBO Addon throws a missing BP Code during "1" click (update)

Dear Community,

I have been meddling with a weird error on one of my personal addons. The problem is, when I hit update button i get the following error

Below you can see the code of the Update Button;

private void Button0_PressedBefore(object sboObject, SAPbouiCOM.SBOItemEventArg pVal, out bool BubbleEvent)

{

BubbleEvent = true;

if (Application.SBO_Application.Forms.ActiveForm.Mode == SAPbouiCOM.BoFormMode.fm_UPDATE_MODE)

{

int cnt = Grid4.Rows.Count;

int rowIndex, ok;

string CallID;

int count = Grid4.DataTable.Rows.Count - 1;

ProgressBar0 = Application.SBO_Application.StatusBar.CreateProgressBar("Checking Completed Service Calls", cnt - 1, false);

ProgressBar0.Value = 0;

for (int i = 0; i < cnt; i++)

{

try

{

showRow = int.Parse(Grid4.DataTable.Columns.Item("CallID").Cells.Item(i).Value.ToString());

ProgressBar0.Value = i;

ProgressBar0.Text = i + "/" + cnt + " - " + showRow;

}

catch { }

rowIndex = Grid4.GetDataTableRowIndex(i);

if (rowIndex != -1)

{

try

{

CallID = Grid4.DataTable.GetValue("CallID", rowIndex).ToString();

oSCs = ((SAPbobsCOM.ServiceCalls)(Globals.oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oServiceCalls)));

oSCs.GetByKey(int.Parse(CallID));

oSCs.UserFields.Fields.Item("U_Completed").Value = Grid4.DataTable.GetValue("Completed", rowIndex).ToString();

oSCs.UserFields.Fields.Item("U_SalesOrder").Value = Grid4.DataTable.GetValue("Sales Order", rowIndex).ToString();

ok = oSCs.Update();

if (ok != 0)

{

Application.SBO_Application.MessageBox(Globals.oCompany.GetLastErrorDescription().ToString(), 1, "Ok", "", "");

}

}

catch { ProgressBar0.Stop(); }

}

}

ProgressBar0.Stop();

}

}

What i noticed though, is that this is caused whenever i use CFL (Choose From List). Here is the CFL Feature i use

The Properties of the EditText Field are:

The CFL datasource properties are:

Any Ideas why this happens?
