Problem with object @user => :person and node

[chinshr]

I want to render the following JSON but don't seem to be able to do it with RABL. Can anybody help?

{"worker": {"id": 1, "name": "foo"}, "errors": {...}, "code": -5}

but instead the errors key is always rendered inside my worker object.

# update.rabl
object @worker => :worker
extends "api/workers/attributes"
node(:errors) {|w| w.errors }
node(:code) {|w| w.api_code }

This relates to answer in #222, but I want errors and code to be rendered as shown above.
