Hey Charles,

There are a couple options for subfiles that come to mind.  You can add
the ability to handle RecordSets as outlined in the second Encapsulation
article:
http://www.itjungle.com/fhg/fhg011205-story01.html

You could either recreate the recordset based on each new
subset/position to, or you could have the Bean return an Array of
records and then use something like Bob Cozzi's Array sorting (sorry,
don't have a link) to provide the navigation.  

In either case, separate the subfile operations from the maintenance
operations. Capture the appropriate key from the selected subfile record
and send use it to create the current Bean.  Then in your maintenance
screen, you can issue the gets and sets and use the Update/Insert/Delete
functions.
