Weird "tag_options" error after upgrading 1.2.6 -> 2.0.2

Hello all. I am REALLY hoping someone can knock me upside the head
with an answer to this because I'm flummoxed.

I'm trying to get my project moved over to 2.0.2 from 1.2.6. I
upgraded the Rails gem (and dependencies) successfully.
rake:deprecated passed with no issues. I ran "rake rails:update".
Everything I think I'm supposed to do for the update.

I'm getting the following error. It happens anywhere I'm outputting
an html tag in my code.

ArgumentError in Sessions#new

Showing sessions/new.rhtml where line #3 raised:

wrong number of arguments (2 for 1)

Extracted source (around line #3):

1: <% form_tag sessions_path, :id => 'loginform' do -%>
2: <p><label for="login">Login</label><br/>
3: <%= text_field_tag 'login', nil, :size => 50 %></p>
4:
5: <p><label for="password">Password</label><br/>
6: <%= password_field_tag 'password', nil, :size => 50 %></p>

This form code is from Rick's "restful_authentication" plugin, with
some minor personal tweaks but nothing that'd cause this issue. This
same error occurs on "image_tag", "stylesheet_tag", etc. I don't
think I have any conflicting plugins installed. I'd have thought that
if I did, they'd show up in the Application Trace output and this
clearly shows it's coming from the actionpack-2.0.2 gem.

Anyone have any ideas. I'm at wits end on this.

Thanx in advance.

Not necessarily: what the trace shows is that when tag_options is
called from actionpack on that lines, the number of parameters is not
what was expected. Do you have a plugin redefining the method
tag_options somewhere ?

Quick update. It's like the "tag_options" it's trying to use is the
actionpack-1.13.6 version, which only has 1 parameter instead of 2
like in actionpack-2.0.2

But I also uninstalled all rails code (including dependencies) from my
computer, leaving only 2.0.2 rails gems and it still gives me the
error.

I'm about to try starting a brand new rails project and slowly port
over my old project code into the new one but boy that sounds like
more work than it's worth.

I coulda had a V8 (man, that ages me. heh). Yeah. I'm too hasty to
post. I shoulda searched. I'm still using the Unobtrusive Javascript
plugin. They redefine tag_options in their "lib/
tag_helper_patches.rb" file.

Time to start working on my javascript code output.

Thanx for giving me that knock upside the head.
