GWT RPC has been thought of as blocking on the server side. Making it async would require changes to the RemoteServiceServlet: most likely the method would be async just like on the client side with the implementation calling the callbacks onSuccess or onFailure.
Your best bet here would be to write a RemoteServiceAsyncServlet by copying from RemoteServiceServlet, hoping for all underlying APIs to be public. Either that or move off of RPC for that call (future proof) -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
