Rails - Jul 2006 - Setting up a Proc for conditional validation (:if option)

I want to use the :if option on one of my validation calls.

Basically I want to validate for a field''s format, but only if the
field
is submitted.  It''s an optional field.

validates_format_of :EMAIL, :if => Proc.new { |email| ! email.nil? },
                      :message => ''is not a valid email
address'',
                      :with => /^[-\w\.]+@([-\w]+\.)+[-\w]{2,4}$/

Is this correct?  It doesn''t seem to be working.

Is it easier to use the method or string forms of :if?

Thanks,
Wes
