I have the same error in Hosted Mode. Production is fine. Making all my types implement IsSerializable fixes the problem, but I'd really rather not have to tie all my objects to GWT like that.
P.S: Maybe unrelated, I get this warning with the IsSerializable fix. I'm getting multiple .rpc files in my build output, i.e. the directory Hosted Mode uses. Only 1 .rpc file makes it to the war file, so that's probably why it doesn't show up in production. 2009-12-11 19:10:13 ERROR org.apache.catalina.core.ContainerBase.
