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  and also posted it to the wiki on
haskell.org . Hope this is ok for you?
