gon.watch produces 500 internal server error

[marcamillion]

I got gon setup fine and am able to successfully access data from my model in my JS. However, once I try to use gon.watch this is the error I get:

GET http://localhost:3000/weights?_method=GET&gon_return_variable=true&gon_watched_variable=weight 500 (Internal Server Error) jquery.js:8215

This is my weights.js.coffee

console.log gon.weight if gon
gon.watch('weight', interval: 1000) if gon

My weights controller index action looks like this:

gon.watch.weight = current_user.weight

I even tried adding a callback and am still getting this error.

Thoughts?

P.S. My environment is:

$ rails -v
Rails 3.2.8
$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.0]

Edit 1: the console.log produces the right object:
Object

Thank you for issue, I'll check it as soon as possible:)

Sorry for delay, I checked by myself and I get right requests to server with code you provided. Can you show server log for 500 error?
