I have a controller called 'exposures' which I created automatically with the script/generate scaffold call. The scaffold pages work fine. I created a custom action called 'test' in the exposures controller. When I try to call the page (http://127.0.0.1:3000/exposures/test/1) I get a blank, white screen with no text at all in the source.

I am using Rails 2.3.8 and mongrel in the development environment. There are no entries in development.log and the console that was used to open mongrel has the following error:

You might have expected an instance of Array. The error occurred while evaluating nil.split> D:/Rails/ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/cgi_process.rb:52:in dispatch_cgi' D:/Rails/ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/dispatcher.rb:101:in dispatch_cgi' D:/Rails/ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/dispatcher.rb:27:in dispatch' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel/rails.rb:76:in process' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel/rails.rb:74:in synchronize' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel/rails.rb:74:in process' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:159:in process_client' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:158:in each' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:158:in process_client' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:285:in run' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:285:in initialize' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:285:in new' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:285:in run' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:268:in initialize' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:268:in new' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel.rb:268:in run' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel/configurator.rb:282:in run' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel/configurator.rb:281:in each' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel/configurator.rb:281:in run' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/mongrel_rails:128:in run' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/../lib/mongrel/command.rb:212:in run' D:/Rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/bin/mongrel_rails:281 D:/Rails/ruby/bin/mongrel_rails:19:in load' D:/Rails/ruby/bin/mongrel_rails:19

Clever readers will notice the 'graph' action. This is what I really want to work, but if I can't even get the test action working, then I'm sure I have no chance.

Any ideas? I have restarted mongrel a few times with no change.

Here is the output of Rake routes (but I don't believe this is the problem. The error would be in the form of and HTML error response).
