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

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.

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.

Edhy Rijo

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. 

I will look into this though.

Just following up to see if I have a problem or if there is a small bug...

Thanks

Tim

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.

Yes, there will be an official release in the coming weeks/month.  No official date at the moment, though.

Hi Ben,

Can/should we all download those DLLs, or will it be an official release shortly to keep everybody in synch?

Thanks!

Edhy Rijo

Hrm, yeah, those DLLs have the fix for FillByParent when the parent is empty.  So, if you're still getting the error, then yes, it might be unrelated.  Could you post the details for the exception that you're receiving?

Sorry Ben, Just want to clarify. Does the code found in the above link solve this problem or do I have to wait until 1.62.

I downloaded and installed the updates (copied to my GAC), but I still get an error with the FillByParent. I'm just wondering if my problem isn't related to this one.
