Hi Orville, I am not sure if all the links you provided are directly linked to the problem : no deserialization of JSON-Data on POST/PUT-Methods. But I might be wrong here.
Anyway : this issue will be looked into soon, hopefully: http://restlet.tigris.org/issues/show_bug.cgi?id=1219 - you might want to register yourself to the issue to receive updates. Back to the issue: the bad thing is that there are no error messages on the GAE side. The data is just not deserialized (parameter == null) when originating from a restlet client (JSE and Android). This means that I cannot provide additional error information to the resolvers. What I noticed also is that the JacksonConverter is not selected. If I "curl" a POST then the deserialization works and the Converter is resolved: "org.restlet.service.ConverterService toObject: The following converter was selected for the [application/json] representation: org.restlet.ext.jackson.jacksonconver...@..." With the restlet clients, to above converter selection output won't appear. When I compared the "curl"-Request and the restlet-Request, I noticed some differences in the HTTP-Headers. That might be a starting point for the devs. Though, as Jerome pointed out - it's holiday time ... so we should be patient.
