What steps will reproduce the problem? 1. ui have a TextArea 2. string have \n 3. com.google.gson.JsonParseException: Failed parsing JSON source: java.io.StringReader@1298826 to Json parse ok Extjs php example(change textfiled to textarea) will work ok, buy jng throw exception. Caused by: com.google.gson.ParseException: Encountered "\"" at line 1, column 2. maybe dobule quoted?

after some test i found reason:
gson do not have method convert JsonElement to JSONString;

JsonElement.toString() not proccess \n \t .... special chars

my solution:

patch google-gson-1.3:

public void toJson(Object src, Type typeOfSrc, Appendable writer) {
    try {
      if (src != null) {
        JsonSerializationContext context = new JsonSerializationContextDefault(
            createDefaultObjectNavigatorFactory(), serializeNulls, serializers);
        JsonElement jsonElement = null;
        if(src instanceof JsonElement){
            jsonElement = (JsonElement)src;
        }else{
            jsonElement = context.serialize(src, typeOfSrc);
        }
....

patch jngine:

public class JsonRequestProcessor extends RequestProcessorBase

where: a instance JsonElement call toString()

change to getGson.toJson(JsonElement)
