I think there's been either a lacking in my explanation, or a lacking
in your interpretation - if you follow my posted code, it does exactly
what you describe.

Display form 1
 -> if valid goto form 2
 -> if not valid redisplay form 1
Display form 2
 -> if valid, use the data
 -> if not valid, redisplay form 2

This is exactly what HTML::FormFu::MultiForm does, but makes it more
simple, as you can do it all within a single Catalyst action - it also
encrypts previous form's data within a hidden field, so you don't need
to revalidate earlier data.

The bit I suspect the OP was getting wrong, was trying to validate
form 2's submission, using form 1.

However, rather than suggest a new module - to get the job done I
suggested what I hoped would only be a minor code change (based on
typical formfu usage, as the OP didn't give any code).
