Hi HAritha,=0A=0AOn closer inspection Json-lib is doing the correct thing b=
y not converting the value of your property 'JSON' into a JSONObject, even =
if it is a well-formed json string. In a previous version it did so, but th=
at caused another bug with simpler json strings. So if you want to transfor=
m that json string into a JSONObject you'll have to do it yourself. There a=
re several options=0A=0A-- Option A=0AJSONObject jsonObj =3D JSONObject.fro=
mObject( textField, jsonConfig );=0AjsonObj.set( "JSON", JSONObject.fromObj=
ect( jsonObj.getJSONObject( "JSON" ), jsonConfig );=0A=0A-- Option B=0A=0A =
JsonConfig jsonConfig =3D new JsonConfig();=0A jsonConfig.registe=
rJsonValueProcessor( "JSON", new JsonValueProcessor(){=0A public Ob=

// not interested in processing the value inside an array=0A =
