Duped find doesn't work as expected

[simmogs]

I've defined a simple dupe using the following:

Dupe.define(:transformation)

After creating a record and then doing Transformation.all, I get a result which is as expected. But when I do Transformation.find(id) using an id I know exists I get the error below.

undefined method `body' for #<Hash:0x00000003578cf0>

I'm using Rails 4.0.4 which uses ActiveResource 4.0.0. I'm using my own branch to allow the use of Rails 4 via the gemspec but maybe it's not that simple. simmogs@54a5304
