An idea: I belive it has many pitfalls :(, but might be useful an idea, tapestry could for example extend such enum (persist worker might trigger it) and add serialization code to it. Then when reloading it could force serializing enum values, plus if the value gets serialized outside tapestry it could be better handled (if servlet container serializes it).
this might only help enums..
