Thanks for the clarification, Mike.  So it is really an issue with the
decorator rather than FormEncode as a whole, correct?  As I mentioned, I
have never ran into issues with FormEncode but I have only just started
using Pylons therefore haven't ran across a huge number of cases with the
decorator.
