Yes, that is all it should do. The next time the record is read the dataset
will bring the fresh version of it from the server again. When coordinating
with cached updates it does get a little tricky. My intent is that it will
simply keep the changed record in the update buffer but if it is cancelled
then the new record from the server will be used, not until such a case.
This is based on the assumption that the update SQL will detect contention
if necessary. Otherwise I don't know how I will merge the record buffers in
the strange case changes are in the client and then changes from another
user are brought from the server.
How do you all think this should work? I'm open for suggestions.
