-----------------------------------
Ishan Chattopadhyaya
You are right. There are 2 places we need to fix this
as a generic JSON serializer , we must support sending a null value for a String
We should also fix this method?
{code:java}
public String stringValue() {
if (fieldsData instanceof CharSequence || fieldsData instanceof Number) {
return fieldsData.toString();
} else {
return null;
}
}
{code}
