Hi Tom.

>> The behavior is that this isn't populating the list at all. It works on some of the comboboxes in this grid but not others. I'm guessing it to be more data related than code related. <<

I'm guessing that you locate is failing because you haven't forced both items to the same case. What happens if you use locate for upper(whatever) == upper(whateverElse) ?

>> Have you seen unusual behavior with data environment defined relationships not working every time? <<

Only the lose nut behind the keyboard. Which, in most cases, is me!
