Seems like your serialization policy file on your server is outdated (thats the <hashcode>.rpc file in your generated js folder, which should be available to the server and always be up-to-date). Do you use an external server? If so, redeploy your app. If you use the build-in Jetty server you may need to hit the "Reload Web Server" Button in Eclipse.
I mostly see this exception when I modify/create serializable classes and then first redeploy to external server and then reload dev mode. That way I deploy an outdated policy file and when reloading dev mode a new one will be generated and I have to redeploy again. So you should always reload dev mode first and then redeploy. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
