Rails - Jul 2006 - Weird validation problem

I have a field called Fax in my model.  I store it as a 10-digit number 
with no other characters but I display it as a nicely formatted phone 
number.  I have a validation on it like this:

validates_format_of :Fax,
  :message => ''number should be formatted using (XXX)
XXX-XXXX'',
  :with => /^\(\d{3}\)\ ?\d{3}-\d{4}$/

If I put 1234567890 (10 digits) in my field, the validation doesn''t 
fail.  I''m guessing it has something to do with my getter and setter
and
when the validation code is actually run.  Is the field being saved and 
then re-retrieved, and formatted "correctly" by my getter before the 
validation call happens?  That''s my guess.

Here is the getter:

  public
  def Fax
    fax = read_attribute(:FAX)
    unless fax.nil?
      fax.gsub!(/\(/, '''')
      fax.gsub!(/\)/, '''')
      fax.gsub!(/-/, '''')
    end

    if (fax =~ /^\d{10}$/)
      sprintf("(%d) %d-%d", fax[0,3], fax[3,3], fax[6,4])
    else
      fax
    end
  end

Here is the setter:
  public
  def Fax=(fax)
    unless fax.nil?
      fax.gsub!(/\(/, '''')
      fax.gsub!(/\)/, '''')
      fax.gsub!(/-/, '''')
      fax.gsub!(/\s/, '''')
    end
    write_attribute(:FAX, fax)
  end

Thanks,
Wes

"doesn''t fail" means that the validation doesn''t
catch the error and
treat it as such.
