Delete / Create Association between ObjectItem in tree and symbol-ObjectItem (Potential / Wire / Cable)

How can I delete an association between an ObjectItem in tree and a Symbol-ObjectItem
Object Kind can be Potential, Wire or Cable

I have tried SheetBop "aucOpExecSheetDelAssocSym", but this does not work in EB 2019 Patch 10... (No runtime error, no User-Log or traceview message) The association was not deleted.
(same example worked in older EB versions)


"OpExecSheetAssocSym" seems to work and to override an existing Association


My sample Code

sheetBops.AddRecord(1006, null); // <-- aucOpExecSheetDelAssocSym

sheetBops.AddRecord(8, shapeItemId); // <-- aucArgExecSheetRef2Symbol

sheetBops.AddRecord(7, objectItemId); // <-- aucArgExecSheetRef2Obj

with

public static void AddRecord(this IList<ExecuteSheetRecordData> sheetBops, int qualifier, object value)

            => sheetBops.Add(new ExecuteSheetRecordData() { Qualifier = qualifier, Value = value });

and

ExApp.ExtendedUtils.ExecuteSheetOperation(sheet, ref sheetBops);

is there any other way / best practice to Delete / Create an Association between Ao/Do of ObjectKind Potential, Wire or Cable?

Thanks a lot!
