Joe: I don't think you understood William's question. AFAIK there is no
solution to William's problem. If you beam an app to someone who already has
the app (typically an older version of it), the old version will be deleted
ALONG WITH ITS DATA. Obviously, we're aware of this problem.
The only work-around I can think of is really ugly. You assign a new creator
ID for each version of your app. You make your app search for old data and
automatically convert it to the new format. This could be as simple as
changing the creator ID of the database, but it could involve arbitrary
format changes as well. This work-around doesn't help if an app is
overwritten with the same version, but this is probably much less common.
This isn't an official Palm recommendation; it's just an idea that might
work. I haven't even tried it.
