-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 you don't send the same data the second time. my experience says that this can have a thousand reasons which are not even hinted at by the error message. something in your class makes the gwt compiler think that it cannot be serialized or the gwt compiler assumes the class is never serialized (it's generally confused by generics)
