Re: IncompatibleRemoteServiceException caused by different RPC Protocol Versions (server: 5, client 6)

I'm getting pretty much the same error, except in reverse:

com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
This application is out of date, please click the refresh button on
your browser. ( Expecting version 6 from server, got 5. )

Have you been able to get around this using 2.1.0.M2?
