Thanks for the info, Arthur. It could be possible that there is some custom stuff that Spring is doing to Seralizable objects that causes the serialization error. Perhaps that's one of the issues that the GWT-SL library tries to sidestep. Using IsSerializable instead sounds like a reasonable workaround if that is indeed the case.
