Well, it's just messy no matter how you look at it. Separate forms seem preferable I guess because the user can keep them both open & visible at the same time. If you follow Ted's and my suggestion of generating a local, flat read-write cursor & do batch updates of the underlying tables when the user indicates that he's ready to commit you'll have more code to write, but the buffering/views issue will become mute. The cursor, in effect, is the buffer and should be easier to manage since it's local. -Lew

I hadn't particularly thought of it as an issue impacting on the end user's ability ("right"?) to design the ui, I thought it was me doing that not them. It was more about the linked data issue and therefore about designing so that cancelling an editing session really cancels all the changes made in that session. Seems to me the views here cause the problem (though being a good idea from another perspective of course), how do different views of similar data communicate, particularly when they're buffered, without changing the underlying data store? Yes, it makes for a messy ui implementation, and that was why I started wondering about it, on the basis that often a design becoming messy is a sign that it's going the wrong way. Unless of course, it's just "real life" being messy, as usual. More of the problem seems to (me to) be that SQL doesn't work on buffered or "local" (to the data environment) data, but the tables on disk, so if I've got a clutch of rows to be added as a result of a users click I either can't do that, or I have to compromise the local, buffered, data, and save data to a "real" file. Sounds like picking it apart into separate screens *is* the way to go, because that gives at least some indication of why some data has been committed and other data hasn't.
