Description
Issue SHINDIG-1506 was solved (see https://issues.apache.org/jira/browse/SHINDIG-1506).
The RPC servlet did not parse the given parameters according to the spec (http://opensocial-resources.googlecode.com/svn/spec/1.1/Core-API-Server.xml#urlAddressing) and therefor were not accessible in the RpcRequestItem.
A correct, and now working, RPC call would be:
/social/rpc?method=people.get&id=req¶ms.userId=@me¶ms.groupId=@self
This needs to be updated in the Getting Started page of the website.
