error response can't be parsed by activeresource when send as json
Reported by Sam | February 28th, 2010 @ 06:06 AM
If I try to use an ActiveResource object and on the server side ocures an error because of a validation or any other reason the client throws an exception with the following trace:
NoMethodError: You have a nil object when you didn't expect
it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each
