Re: IncompatibleRemoteServiceException SerializationException Issue.....
The error is: Caused by: com.google.gwt.user.client.rpc.SerializationException: Invalid type signature for com.sample.project.shared.model.UserInfo I google and found some explanations (thanks a T. Broyer again) in this threadhttp://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.
