Thanks for your advice, its funny but my boss just said the same thing
(about using flash)
My main goal was to not make another trip to the server (hence the use of
javascript and wddx)
Only the neccesary fields would be sent to the browser. I suggested using an
applet but my boss
pointed out without a java enabled browser with the correct version this
functionality would be useless,I would have thought the same went for using
flash as well.
The two goals i was aiming for were not to perform another query and not to
make another trip
to the server. Is this possible with a cached query and Flash?
Thanks

I waited a while before weighing in on this, but here goes...
<rant>
I hate to see this type of design, where large amounts of data (most
of it, probably, unneeded) are schlepped back and forth along the
highway we call the internet. It clogs the net with [largely]
unnecessary traffic.
Further, the verbosity of WDDX packets only exacerbates the problem
by increasing the amount of the data sent (over and over and over...)
Look at a WDDX Packet and you will see it's size is many times larger
than the actual data content.
Don't get me wrong, I use WDDX every day, and used properly it is a
valuable tool...
But, WDDX is not meant to be an extension of the client/server system bus.

Use CF to cache your queries at the server
in your CF program select only the required rows, and send them to the
client
If you want to improve this more, write a Flash front end for the
client so that only the field names and data need to be sent to the
client (eliminates retransmitting the entire HTML document)
I think you will experience an overall performance improvement and
better use of the server, internet connection, and the client...
..... kind of an *environmentally-friendly* program design!
And, the user experience will be much improved too.
