I wrote a CFC a while back that takes form field names that use array or structure syntax and converts them into actual arrays and structures on the CF side (to any arbitrary level of nesting). It's handy not only for dynamic fields (no more trying to parse user_1, user_2, etc.) but also for building whatever collections of data you want (i.e. let it build up a user structure and pass that into your model rather than doing it manually, or passing the whole form scope, etc.) http://formutils.riaforge.org/index.cfm
