This is a standard problem, and it'd be nice to have good code to do
it. I'll volunteer mine as a starting point to get things rolling. The
following works, and I'm looking for ways to improve it. I seem to recall
Form fields became a Structure somewhere along the line. The following
works in CFAS 4.0.1
OH, in qry_SetWDDX.cfm I got stuck on Fusedocs, I'd appreciate any comments
on finishing that.
Finally, you'll notice I set Client variables in my own database, so, among
other things, I can avoid making CF parse a #-delimited string for every
client variable request.
best, paul

I get arbitrary set of Form Fields sent to me. I store these in a database.
I put the field names and their values into a Structure.
I convert the Structure into a WDDX packet and store it in a database.
