Issue upgrading to Rails 2.x

[Mauro Botelho]

I upgraded to rails 2.x and now I'm getting an exception whenever
trying to load a story regarding the constants. I'm not an experienced
rails developer, so I'm stuck :(

Here's the stack trace:

I solved my own problem.

I had to change the composed_of declaration.
