I typically use cfparam to create a variable with a default value, and check against the default value using a cfif. Does IsValid() offer any benefits other than the method I use? (Such as using less server memory by not creating variables, ect.)

All discussions I have been in over 508 compliance have pretty much resulted in cannot rely on JavaScript for anything. Though it does seem like every place and person has a different interpretation of 508 and some of those being vastly different than the others. On another note, I'd also look into the IsValid() CF function for the server side validation. I'd check to make sure required fields are populated and I would also ensure they are the proper datatype for the database and also do not exceed any size restrictions on the database side.

If you are on an intranet where the user environment is controlled, it is less of an issue, but for internet facing sites it is very important. In general, you want to do everything you can to prevent users from ever seeing a ColdFusion error. I can't speak to 508 issues, but i am not sure how screen readers would handle the JS validation, either.

I'd take a quick look at jQuery form validation or any of the other JS offerings, you probably could quickly get it in there when taking out some of the CFFORM stuff.
