One small problem with this: my checkbox is now validated with
onvalidate which only runs when everything else validates. I want the
'must agree to terms' error to popup any time the form is submitted
without the checkbox checked, not just when it's the only think that
doesn't validate. If I could determine whether this is a postback the
way accepts does, I could just invoke my validation code manually.
Poking into the FORM.accepts code, though, I noticed onvalidate may be
a dict of {'onsuccess': func, 'onfailure': func}, so now I just have:
onvalidation={'onsuccess': validateTerms, 'onfailure': validateTerms}
...and that seems to do the trick.
BTW, I got confused by INPUT's value arg. I kept treating it like
_value until I realized that value is only meant to be set to True to
turn the checkbox on by default. Maybe deprecate 'value' in favor of
'prechecked' for this purpose to avoid the confusion.
