Hi Marc,
You should change
https://github.com/racket/web-server/blob/master/web-server-lib/web-server/formlets/input.rkt#L148
so that if the list is empty, then you return some value that was
passed as an extra keyword to `input-group` and `radio-group`. Can you
check that and see if it works fo
Hi again,
I just realized that I never figured out how to get radio-groups not to
raise an error when no option is selected. I manage to put defaults for
input-string and so on, by doing what Jay suggested and redefining my own
through the use of 'default and 'input.
In the case of radio-group, w
Done, although since it is my first pull request, let me know if I did it
wrong (tried first without forking, which of course was nonsense).
I tried to find a way to have the 'id' on radio the same as the 'for' on
label, but I couldn't figure out well enough what is going on.
Cheers,
Marc

So, turns out I can answer my own question, if ugly hacks count.
I copy-pasted (yep, DRY is my guiding principle: Do Repeat Yourself) the

of the code that creates the HTML in 'input-group' from
(for/list ([vn (
Thanks Jay.

Hi Marc,
Most formlets are typed as `(formlet/c (or/c false/c binding?))` where
the `binding?` is returned when the thing is there and the `#f` is
returned when it isn't. However, if you use `required`, then an
exception is thrown on the `#f` because the form element must be
present. Formlets like
Thanks.
Another question about formlets: when I use (formlet-process formlet-name)
it will often raise errors when a field doesn't have a value. Is there an
easy way of capturing errors, in particular to show the form as it was
