Namespace collision in 1.01 vs broken JSON parser in 1.1 -- help!

[Aaron Russell]

Seems like I'm stuck between a rock and a hard place. I have a resource in my Rails app called "response". Unfortunately, this name clashes with ObjectiveResource's Response class. I tried upgrading to 1.1 (yfactorial's 1.1, that is) and using the new [ObjectiveResourceConfig setLocalClassesPrefix:@"ABC"]; notation to define a local prefix for my app, but now the JSON parser has an exception that crashes my app.

Here's what's on the console after my app tries reading in some JSON:

I either need a way to work around the namespace conflict issue with 1.01, or I need a way to avoid this crash on 1.1. Can anyone point me in the right direction on this?

Ended up going back to ObjectiveResource 1.01 and deliberately misspelling my Rails class and adding some stuff to the routes to handle the misspelt name in the URL and some filters to the JSON output to make it match the mis-spelt name the iPhone app is using. A bit of a hack I guess, but it works.

"...deliberately misspelling my ObjectiveResource class", that should've said.
