Hi. I'm with the following issue: I am able to update any workitem property via web request, except it's state. I've already made lots of changes in several workitems using the same approach, but when I needed to change the state, it seems that RTC ignores my request. The status comes as 200 - OK, but no change is made.

{ "dc:description":"this is a description.","rtc_cm:state": [ { "rdf:resource" : "https://gidhmp.caixa:9443/ccm/oslc/workflows/_0_iN4G09EeGGMqpyZT5XdQ/states/DemandaNeg/DemandaNeg.state.s3" } ] }

            HttpWebRequest documentPut = (HttpWebRequest)WebRequest.Create(resourceUrl);
            documentPut.Method = "PUT";
            documentPut.CookieContainer = cookies;
            documentPut.Accept = "application/json";
            documentPut.ContentType = "application/x-oslc-cm-change-request+json";
            documentPut.Timeout = 300000;
