[GoogleCodeExporter]

What steps will reproduce the problem?
1. Load admin of site using activescaffold
2.
3.

What is the expected output? What do you see instead?
Admin forms, links, etc are expected.

Instead I see undefined method `[]' for
#<Enumerable::Enumerator:0x7febc61c3e28>

What version (or revision) of the product are you using?

activescaffold 1.1.1  (I think)
ruby 1.8.7

Thanks for reporting this. If possible, could you try this with rails 2.3 and 
the
latest activescaffold we can at least see if it is fixed and go look for what 
fixed
it to backport said fix. Alternatively, if you could attach the model and 
controller
we might be able to see your issue.

Activescaffold is now hosted on github so make sure you grab that version. The 
1.1.1
from svn is over 2 years out of date.

Hi.

This is running without a problem on the production server with 1.8.6. 
Unfortunately, when the staging server was created, ruby 1.8.7 was installed by
default.  I'm not in a position to upgrade the production server to rails 2.3 
at this
time.  But I might be able to test this for you on the staging server later 
today.

Your other suggestion was to send the model and controller.  

Here's the error - 

 Showing vendor/plugins/active_scaffold/frontends/default/views/_list_header.rhtml
where line #3 raised:

undefined method `[]' for #<Enumerable::Enumerator:0x7f6ecd0d6dd8>

Extracted source (around line #3):

1: <% if active_scaffold_config.action_links.any? { |link| link.type == :table 
} -%>
2:   <div class="actions">
3:     <% new_params = params_for(:action => :table) %>
4:     <% active_scaffold_config.action_links.each :table do |link| -%>
5:       <% next if controller.respond_to? link.security_method and
!controller.send(link.security_method) -%>
6:       <%= render_action_link(link, new_params) -%>

Sorry to be dense, but which model and controller and I sending to you?  Is it 
from
activescaffold or the from the app using it?

Thanks.

I've attached one of the sections that's showing the errors.

Let me know if there's something else that's needed.

Thanks.

It's a compatibility problem between rails and ruby 1.8.7
In rails 2.2 chars was deprecated because a chars method was added to ruby 
1.8.7,
and it was renamed to mb_chars. The method 'first' is added by rails and it use
chars[1], and it fails in ruby 1.8.7. In rails 2.2 it uses mb_chars[1], so it 
works.

You can change @params_for[:controller].first(1) == '/' with
@params_for[:controller].chars.first == '/' in
#{RAILS_ROOT}/vendor/plugins/active_scaffold/lib/helpers/active_scaffold_helpers
.rb

Thanks for your reply.  Will this need to be changed throughout active 
scaffold.  I'm
getting rjs errors from various spots including create.rjs

TypeError: $$("#admin__blog_posts-create--form a.cancel").first().link is 
undefined

Probably it's another compatibility issue, between your ActiveScaffold version 
and
newest browser versions (Firefox 3 and Safari 3). Try with fixes from bug 553:
