JsonConverter does not decode JSON?

[tmcguire]

When calling JsonConverter.decode(s), the JSON string s does not seem to be read correctly. Specifically, JsonConverter seems to discard the first two characters of value strings:

{"menu":[{"heading":"one","href":"one/"}]}

produces a Map with the expected structure but that looks like it comes from the JSON:

{"menu":[{"heading":"e","href":"e/"}]}

Looking at JsonConverter.java, it seems to be expecting some kind of type tag at the beginning of the string, but that does not conform to any JSON grammar I've seen.

Yes i have the same problem. Is this a bug or are we doing something wrong?

JsonConverter needs an own format. It should not be used in a general case. This kind of tag is needed to support any java dataformat you might want to support.

What shall i use then? I now encode my json with 2 extra spaces infont of the value;

result.put("message", "  " + result.get("message"));

and decoded like this:

Map<String, Object> result = JsonConverter.decode(jsonStr);

There is no buildin class for your usecase. GWT offers JSONObject you can use.

The standard GWT JSONParser correctly parses JSON.
