Any thoughts other than abandon cfform?
There was a time, a while ago, where CFFORM was kind of neat. I used it a few times for generating Flash forms (mostly for security, ironically.) Now, Flash is either dead, or dying; no point, now.
But, IMHO, these days CFFORM should never be used (those who disagree, hold your hate mail.)
I never liked the built-in "validation" of cfinput, etc. I've always built validation from scratch (client- AND server-side) that gives so much more granular control. So, if that's the reason you're using CFFORM, please do yourself a favor and learn basic validation (preferably server-side; client-side is nice, but can't be relied upon.) You can use Regular Expressions to validate integer, float, etc.
