Protype ajax validation problem

[quote author="mdowns" date="1218483936"]Have you tried this pattern?

Code:

function required() {
    if(!preg_match('^\.+$', $this->obj->input->post('value'))) {
      print "This field is required.";
    }
  }

Yes, I have. I even tried '^\/S+$' trying to match any white space. I'm going to post this under bugs at this point in time because there is no reason that myself or severals other can come up with that this should not be working.
