Why doesn't Jayrock (.NET JSON-RPC Framework) like my request?

Question

Hi quick question about Jayrock... I have a Jayrock JSON-RPC web service that generally works fine. However, when I try to post to my jqGrid editUrl, Jayrock throws an error. The web service works fine in other situations.

Anyone have a clue why Jayrock doesn't like the following request? Perhaps a way to configure Jayrock to accept this request?

Request:

Answer 1

Because you send application/x-www-form-urlencoded request with "form-like" post data instead of application/json with correct json object.
