I google and found some explanations (thanks a T. Broyer again) in this thread<http://groups.google.com/group/google-web-toolkit/browse_thread/thread/dcc7441ed78bc3ee>. I paste the here the explanation: The "invalid type signature for" message indicates that the object used by the client is different than the one known to the server (at compile-time, a checksum of the object's fields is computed and sent along with the object's class in the RPC payload; the same checksum is computed at runtime on the server and compared to the one received from the client). Please read the details in thread, perhaps help to you.
