Hi Chris,
you're absolutely right. The mistake was in the where-part of withForm.
The function handleOk' gets an environment d as argument but uses an
extractor that was created without passing d to runFormState. I've put a
corrected version on hpaste [1] and also posted it to the wiki on
haskell.org [2]. Hope this is ok for you?
Regards,
Martin.

That means that you don't have input0 in your environment, maybe you're
passing in an empty environment?

Hi Chris,
thanks for the updated example. Compiling works now. But when I try to
run it I alway get error messages like
["input0 is not in the data","input1 is not in the data"]
Regards,
Martin.

Hey Martin,

I found a blog post concerning formlets [1] in the web. Since looks
very interesting I tried to compile the sample code with recent
versions of HAppS and formlets from hackage. But this didn't work as
the API of formlets has changed since this post.
I tried to adopt the code to the new API but I was unable to finish
this since there is a new monadic context I don't know to handle in
the right way.
So my question is, is there an updated version of this sample code
in the web or has anybody tried to adopt it and can send me the
results?
Yes, I'm sorry for that. The API is still very immature and due to
changes, that's also why it hasn't been officially announced yet.
I've just put an updated example at http://hpaste.org/10568, hope
that'll work for you. I guess we should build a small homepage /
wikipage that always has an up-to-date example.
