Spinning my wheels on custom validator

[Dave S]

I'm trying to write a custom validator to use in a form, and I'm thinking it should be simple but the brick wall is leaving dents on my forehead.

Except for getting the occasional "pretty please fill the form" (as when reloading the page with F5),
I get "congratulations" in the flash, and neither accepted values nor rejected values, and the debug stuff doesn't show on the console.

In the samples below, I've hot-wired the form to always produce errors, except it doesn't.  I seem to missing a connecting rod somewhere.

Thanks for your help.

in db.py:

from gluon.validators import Validator

class IS_HEXSTR(Validator):
    def __init__(self, format='%c%c%c%c', error_message='must be hex string like A09F!'):
        self.format = format
        self.error_message = error_message
    def __call__(self, value):
        try:
            intvalue = int(value, 16)
            print "should be valid " + intvalue
            return (intvalue, "BURGLE")
        except:
            print "invalid " + value
            return (value, self.error_message)
    def formatter(self, value):
        return value.upper()

(The import was added after reading
<URL:http://www.web2pyslices.com/slice/show/1586/obligate-a-field-just-in-case-another-one-has-value>)

In my controller:

def activate():
  form = FORM('Activation code:',
              INPUT(_act1='left', requires=[IS_NOT_EMPTY(), IS_HEXSTR()], _width=4),
              INPUT(_type='submit'))
  if form.process().accepted:  
        response.flash = 'congratulations'
  elif form.errors:
        response.flash = 'form has errors'
  else:
        response.flash = 'pretty please fill the form'
  return dict(form=form)

and the view is :

{{extend 'layout.html'}}
<h1>Activate Enmotus License</h1>
{{=form}}
<h2>Submitted variables</h2>
{{=BEAUTIFY(request.vars)}}
<h2>Accepted variables</h2>
{{=BEAUTIFY(form.vars)}}
<h2>
    Unaccepted variables
</h2>
{{=BEAUTIFY(form.errors)}}

Has your app been compiled?

Not intentionally.

The only .pyc file I see around my app is __init__.pyc in the app-level directory.

Gah, pfooey! I shouldn't change"_name" to "_act1", should I?

Also, it seems I want to change the "size" of the input field, not the "width".  But I don't see 

_size=4

working for me.  How should I do this?

It looks like Boostrap is beating me here, forcing the width to 300px.   If I change the _type to number, then I get a width of 206px (still bigger than "size=4" should be), and it breaks my input because someone (browser?) assumes a number is decimal.
