We were discussing that annotation in this thread: http://groups.google.com/group/google-web-toolkit/browse_thread/thread/71e0e7ca92425ad/0f1d4d5cf52875cb?lnk=gst&q...@gwttransient+#0f1d4d5cf52875cb
The annotation only works if all your classes with all the relation classes belongs to the GWT module and all of them are serializable by GWT. If you have class A which is not serializable by GWT and class B which is serializable but has a relation to class A (through a field and their corresponding getter and setters), no matter if you use the GwtTransient annotation, the compilation will fail saying that class A is not serializable or that it does not belong to the module and that it cannot find the source code.
