vb.net ERROR 1003 when update object (not new object)

[mark-piller]

I took your class and wrote the following program:

'SAVE FIRST OBJECT
Dim testObj As New ANAGRAFICA_INTERVENTI()
testObj.COSTO = "test value"
BackendlessAPI.Backendless.Data.[Of](Of ANAGRAFICA_INTERVENTI)().Save(testObj)


'FIND FIRST OBJECT
Dim firstObj As ANAGRAFICA_INTERVENTI = BackendlessAPI.Backendless.Data.[Of](Of ANAGRAFICA_INTERVENTI)().FindFirst()


'SAVE/UPDATE FIRST OBJECT
firstObj.COSTO = "different value"
BackendlessAPI.Backendless.Data.[Of](Of ANAGRAFICA_INTERVENTI)().Save(firstObj)

The program ran just fine. Here’s the result in console:
