Rails - Oct 2008 - ActionMailer template gets nil param from non-nil deliver_

Rails 1.2.6
ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]

=Summary:

I pass a non-nil parameter to an ActionMailer class''s deliver_* method.
The corresponding * instance method for the ActionMailer gets a nil
instead. Disaster ensues.

Will someone please tell me what I''m doing wrong?

=Details:

I have an ActionMailer::Base class with the following template method:

  def request(req)
     # Control reaches here. req is logged as nil:
     logger.info "in MyMailer#request, request = #{req.inspect}"

    # Exception in the following, owing to the nil:
    subject "Request for authsmtp exception (#{req.permit_ip})"
    # etc.
  end

This is invoked through this method in my ActionController::Base class:

  def create
    @permission = Permission.new(params[:permission])
    if @permission.save
       # @permission is non-nil, and as expected, in the following log:
       logger.info "In PermissionsController#create, @permission
#{@permission.inspect}"
       MyMailer.deliver_request(@permisssion)   # Mail the request to
approvers.
      # etc.
    end
  end

As noted in the comments, @permission is non-nil when passed to
deliver_request(). In request(), the corresponding parameter, req, is
nil. I am stymied.

I have searched the archives, and nothing obvious presents itself. Will
someone please help me get started again?

(This is my first post through this forum software. I am hoping it
doesn''t destroy linebreaks or indentation. If they do get clobbered, I
apologize, and would like to know how not to get them clobbered.)

Never mind. The cause was a typo in my own code, and my (apparently 
failing) eyes never managed to see it.

Thanks for the attention of whomever paid attention.
