Application Crash while updating a Bill of Material

Question

Hi,
I am currently developing an addon for SAP Business One. When updating a BOM record I have the following problem:
If i call the Update Method of the ProductTrees Object the SAP Business One Application Crashes with the Error:
"Runtime Error!
Programm: E:ProgrammeSAPSAP Business OneSAP Business One.exe
R6025
- pure virtual function call"
The Code i am Calling looks like this:
Protected Sub closeBundleBillOfMaterial(ByVal sCode As String)
        Dim oRec As SAPbobsCOM.Recordset = cInit.getInstance.getSboCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
        Dim sSQL As String = "SELECT OITT.Code FROM ITT1 INNER JOIN OITT ON ITT1.Father = OITT.Code WHERE ITT1.Code = '" & sCode & "'"
        Dim oBOM As SAPbobsCOM.ProductTrees = cInit.getInstance.getSboCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oProductTrees)
        Dim iRetVal As Integer = 0
        Dim sItemCode As String = ""
        Try
            oRec.DoQuery(sSQL)
            oRec.MoveFirst()
            While oRec.EoF = False
                sItemCode = oRec.Fields.Item("Code").Value
                If oBOM.GetByKey(sItemCode) Then
                    oBOM.UserFields.Fields.Item("U_Status").Value = "C"
                    iRetVal = oBOM.Update()
                    If iRetVal <> 0 Then
                        Throw New Exception("Fehler bei Methode Update in closeBundleBillOfMaterial")
                    End If
                End If
                oRec.MoveNext()
            End While
        Catch ex As Exception
            cLog.err("Fehler beim Ermitteln der verbundenen Stücklisten. ", ex)
        Finally
            cUtil.deleteObject(oRec)
        End Try
    End Sub
My stats are:
- SAP Business One 8.8 PL 16
- SQL Server 2008 Standard Edition with SP2
- Visual Studion 2010
I hope someone has a solution for this problem. Thanks a lot.
Regards
Michael

Hi experts;
I´m getting the same error on one of my ADDONS. Did migrating the SAP B1 database to PL 18 Worked? I'm very frustrated with this error. Thanks for your hekp.
