I know that files can't be uploaded via ajax using a cfform
in a cfdiv, and that the accepted method to "simulate" this is to
post the form to an iframe. However, this has one significant
drawback - by switching to a <form> in place of the
<cfform> (so the form can be posted to the iframe) you can no
longer utilize the field validation provided by cfinput. Has anyone
come up with a way to handle file uploads without losing the
ability to use cfform (and thus cfinput)?
