Could you pass in the Form.cfm url along with the form, hidden fields maybe. Then if the data is valid go to a function that calls Data.cfc or if the data is invalid then it goes to a function that returns the form fields back to Form.cfm using the url parameter.
Just a thought. I have been mulling the idea of using cfc's in a similar method.
