Here's what I've got, at the moment. So far, it's only Transfer =>
Flex, and I haven't completely fleshed things out, so I'm not sure
what traps I'm about to hit.
Also, the Flex form doesn't have all the right field types, and I've
got an issue with null dates, but it's a start. I'm posting this
because it would have saved me a good deal of stumbling around, and it
might make some things click for somebody coming at this fresh.
(Finally, of course it's an invitation for welcome criticism and insight.)
Thanks,
Jamie
