Queue Order Changing

D,

So I'm working on the queue order stuff, and you said that you wanted
to reference changes by the position in the db, not the webpage.

So okay, what I have is a collection of objects in a series, numbered
0-n (the web page index) and each contain a db position that I get
from the server.

Now, when a user changes an item's position, I check the web order,
and from there I can figure out which item moved from where, and I
can tell you that "db pos item N moved to replace db pos item M" ...
But I don't know how you're storing stuff in the db, so does that now
update the item position values? So, does pos item N now change its
position value to M? And do all of the items in between shift their
position values as well?

The collection maintains the original position values (the web, 0-n
numbers) so I can track an item's movement during multiple orderings.
(Until they refresh the page, of course.) I just don't know if your
db position values are fixed or what.
