New Rails 3.1.0 App, Request Failed (code 500, Internal Error)

[JB]

Steps to reproduce:

Start with a fresh gemset and a fresh install of rails:
rvm gemset create tolliver
rvm use 1.9.2@tolliver
gem install rails
gem install active_scaffold

Create a brand new application:
rails new myapp
cd myapp

Add the following to Gemfile:
gem 'active_scaffold'

Run:
bundle install

Edit app/assets/javascripts/application.js
//= require jquery
//= require jquery_ujs
//= require active_scaffold
//= require_tree .

Edit apps/assets/stylesheets/application.css
/*
*= require active_scaffold
*= require_self
*= require_tree .
*/

Create config/initializers/active_scaffold.rb
ActiveScaffold.js_framework = :jquery # :prototype is the default

rails g active_scaffold Contact company:string name:string notes:text

rake db:migrate

rails server

Browse to: http://localhost:3000/contacts

Click the Create New button.

Results in: Request Failed (code 500, Internal Error)

log/development.log shows:

Completed 200 OK in 43ms (Views: 7.9ms | ActiveRecord: 0.0ms)

So it looks like everything is rendered okay. I don't see any errors
and I have no idea what I did wrong. Any suggestions?

This step is not needed, if you have gem 'jquery-rails' and you don't have gem
'prototype-rails', ActiveScaffold detects it and setup js_framework.

It should be fixed in master branch. Try it, with gem 'active_scaffold', :git =>
'git://github.com/activescaffold/active_scaffold.git' When all it's working I
will release a new version.

My simple case works now, thanks!

[JB]

Thanks Sergio, but that didn't resolve the problem. I'm still getting
the 500 error.

Can you send response headers of new request? It should respond with right
content type using git

[JB]

Sergio,

The response headers don't contain a Content-Type. Here is what comes
back:

Okay, this is weird. I turned JavaScript support off and things seem
to work. I turned it back on, and now things are working. I wonder if
it was a caching issue with the browser? However, the response still
doesn't contain an entry for Content-Type . . .

I got content-type text/html when it didn't work, and text/javascript now
