Just in case, have you read the doc? http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideHandlingExceptions and http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/rpc/IncompatibleRemoteServiceException.html 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). See com.google.gwt.user.server.rpc.impl.ServerSerializationStreamReader#validateTypeVersions http://www.google.com/codesearch?q=%22invalid+type+signature+for%22+package:http://google-web-toolkit\.googlecode\.com&origq=%22invalid+type+signature+for%22 It can be the case that you didn't re-deploy the *.gwt.rpc files to your server after making some change to the object (in case you're using the -noserver mode): http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideDeRPC -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
