| | Hi Ben, The exception I'm getting when sch_SheduleBO1 is empty is: 'SQL Exception Unhandled by user code' Line 1: Incorrect Syntax Near ')'. My Code: Me.Sch_ScheduleBO1.FillAll()Me.Sch_ScheduleDetailBO1.FillByParent()If I add 1 record to my Sch_Schedule table, everything works fine. I also attached the DEBUG information for the two fill methods. Stacktrace: at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)

| I have not had a chance to set this up, but it would probably be a good idea to just add a test around the DetailBO1 before calling it. If ScheduleBO1.Count > 0 Then
DetailsBO1.FillByParent()
End If I will look into this though. |

| | Hi Trent, Just to let you know that today I was bit by the same issue, I got the same error. Obviously using the count test will work in this case, but I think this should be fixed ASAP.

| | From what I can tell the issue is that the parent BO doesn't have any records. In that case, just test it prior to calling the Fill method...which is better anyway. This is already on my list. But you are ALWAYS better off being pre-emptive when dealing with emtpy tables, BOs, etc. |

But you are ALWAYS better off being pre-emptive when dealing with emtpy tables, BOs, etc.Yes, you are right, I have not even noticed that in the same form I was using the BO.count check as you suggested here and was blocked by the error, and even took the time to check the forums before posting. Well I am still getting used to SF  and so far I love it
