I inspired myself of Best Way To Handle Auto Selection Of New Row In Table - #2 by shawntax and decided to use a TemporaryState that gets set in the Success handlers, with the new id.
I then have a transformer that translates that id into a row index from the table data.
I then use the value of that transformer as the default index in the table.
It seems to me that this would be a fairly common use case, and therefore something that may be a bit simpler to implement?
