Sony, I disagree with taking an event-based approach to RPC, but this isn't really the forum for that discussion
John, My problem is not Class serializability, but rather the fact that the GWT compiler rejects any code path that has "SomeServerProcedure.class", since the compiler thinks it will need to translate that class regardless of whether any class or instance members are referenced. I'm suggesting that the compiler is a little bit too eager. When I use annotations, this isn't a problem, since they are simply dropped by the compiler and kept by the server (where I need them). However, that leads to an unnatural wrapping situation, where I basically have a marker class on the client-side that references a server procedure. Does that make sense? I'm not sure if I'm explaining this well, and I can give an example, but it will take a little more time than I have immediately available. I'll probably write it up tonight.
