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:

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).
