It works fine with BlazeDS; When comparing RemotingMessage in BlazeDS and GraniteDS, it appears that the classes are a little different :

In BlazeDS :
RemotingMessage extends RPCMessage extends AsyncMessage

In GraniteDS :
RemotingMessage extends AsyncMessage

RPCMessage contains the fields which are not undertood by GraniteDS, and this class has not been patched in GraniteDS. So you may have to update the patched flex.messaging.messages package.

RPCMessage seems to be a BlazeDS specific class and doesn't appear in any Flex 2/3 standard distribution. BlazeDS applications should be recompiled with a standard Flex2/3 compiler before any deployment in GDS.
