Attached is a reproducible example of my problem. It simulates a table with
10 existing rows, and the user has clicked on an 'Add New' button (not
shown). The UI added a new line to the table. If I then click on a
different line, the UI asks if I want to abort my add. When I say 'No', the
code does a selectRow, to get back to the newly added row, but the row that
I clicked on still shows as highlighted, even though currentRow shows the
last, newly added row. I believe the newly added row should now be
highlighted, but I can't seem to make that happen.
I hope this makes sense. I know it's a bit convoluted, but hopefully when
you run the app it will make more sense.
Is this a bug? Or am I missing something? Anything you can do to help
would be sincerely appreciated.
TIA,
Kerri
