I think that htmlfill does the most reasonable thing given the
situation. The value attribute is required for inputs of type
checkbox, and so htmlfill checks the checkboxes with the given name
_and the given value_.

I'm guessing that you're using htmlfill here to pre-populate your
form. If you're going to do that, I think that something along the
lines of your second attempt is the way to go. I don't use htmlfill to
pre-populate my forms, and I'd recommend against it to anyone that
asked. I use my templating language. htmlfill is super-useful for
redrawing forms after failed validation, but it always felt like it
was more work to use htmlfill to pre-populate than it was worth.
