Hi Tomek, Isaac is probably on the right path here. If you switched to GWT 1.5 and changed the implementing type from IsSerializable to java.io.Serializable, you would only receive the error messages talking about isSerializable if the .gwt.rpc serialization policy file wasn't deployed or wasn't accessible. The GWT RPC mechanism defaults to the IsSerializable convention if it can't find the serialization policy file or if it can't find the serializable type listed.
Hope that helps, -Sumit Chandel On Fri, Jan 9, 2009 at 10:02 AM, Isaac Truett <itru...@gmail.com> wrote: > > Are you deploying the gwt.rpc files from compilation?
