Rails - Jun 2005 - ActionMailer bug? (very strange)

I may just be blind after too many hours of coding, but I''ve
encountered what seems to be a very strange bug.

I''ve got an ActionMailer called Mailman:

class Mailman < ActionMailer::Base
  def comments(name, email, comments_text, sent_at = Time.now)
    @subject    = ''Mailman#comments''
    @body       = { "name" => name, "email" => email,
"comments_text"
=> comments_text }
    @recipients = ''myemail-+LBmYUDmh58@public.gmane.org''
    @from       = ''anotheremail-+LBmYUDmh58@public.gmane.org''
    @sent_on    = sent_at
    @headers    = {}
  end
end

I create a mail object in my controller:

def submit_comment
        name  = @params[:name]
        email = @params[:email]
        comments_text = @params[:content]
        email = Mailman.create_comments( name, email, comments_text )
    #    email = Mailman.deliver_comments( name, email, comments_text )
    #    redirect_to( :controller => ''news'', :action =>
''list'' )
        render_text( "<pre>" + email.encoded +
"</pre>" )
    end


And my template: (comments.rhtml)

From: <%= @name %>
Email: <%= @email %>
Comments:

<%=comments_text %>   


Now for the strange part... @name and @email are returning expected
values, but @comments_text does not.  @comments_text is nil.  I did a
render_text from within the controller only on comments_text, which is
being passed to the mailer, and it seems okay.  My mind was boggling
why it wasn''t getting to the template.  So I did a
<%instance_variables %> on the template, and lo and behold, there is an
instance variable called @commments (yes, with 3 m''s).  Where the heck
did this come from?

$> grep -R "commm" *
>From the root of my rails app, and I get *nothing*
Where in the heck is @commments coming from?  Why is @comments_text
not getting to the template?  Part of me is afraid that my hours of
coding have left me impaired, but I can''t seem to figure this out.

I can''t say I figured out what was causing the problem, but it is
working again.

I restarted Apache, and that fixed the problem.  For whatever reason,
something was getting cached ... and this cache was persisting ( for
at least 20 minutes while I was trying to figure out the problem).  I
didnt not change my code, but before the httpd restart I had the
problem, and after it was fixed.

*shrug*

This is probly just an email typo, but if not, it should be <%@comments_text
%> in your view, instead of <%= comments_text %>...
