Use native JSON.stringify through JSNI? The problem with com.google.gwt.json is that it creates a lot of objects and uses a lot of JSNI which slows down DevMode. If you don't mind running a patched GWT, there are a few issues that need to be fixed (most of them have pending reviews): - Elemental JSON can't be used without bringing the whole Elemental (which breaks DevMode<https://code.google.com/p/google-web-toolkit/issues/detail?id=7481> ): https://gwt-review.googlesource.com/4210 - Some of Elemental JSON is broken in prod mode (OK, not really relevant here): https://gwt-review.googlesource.com/4050 - Some of Elemental JSON is broken in dev mode: https://code.google.com/p/google-web-toolkit/issues/detail?id=7484 (partly fixed by above review) Once that's fixed, you could then use: payload = ((JsJsonValue) jsonDataFromJSNI).toJson(); (note: uses JSON.stringify under-the-hood) The next step will be to "port" AutoBean to use elemental.json instead of org.json and add an overload to AutoBeanCodex.decode that takes a JsonValue. (side note: the data you get from the page is JS, not JSON; JSON is a serialization format, if you have objects, then it's JS, possibly expressed as JS literals; this is one reason why JSON-P is completely misnamed: there's no JSON in JSON-P, at all) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
