Anil,
That is the expected behavior because numbers in JSON can never by null, only objects.
It may be a bit confusing at first because numbers in java come in two flavors: primitive
and wrappers, wrappers being objects after all.
But there is a way to override this behavior, you may register a DefaultValueProcessor to
return whatever value (any valid json value that is) that your app requires.
Cheers,
Andres

Subject: [json-lib-user] Question about null Number serialization
Apologies if this is a FAQ,
but I tried for some time to find it and couldn't.
If I have a bean with a Long or Number property, e.g.
class TestBean {
private Long number = null;
public Long getNumber() { return number; }
public void setNumber(Long number) { this.number = number; }
}
and serialize an instance where the "number" property is null, for
example using
JSONSerializer.toJSON(new TestBean()).toString()
it gives the result
{"number":0}
and deserializing this gives an instance that is not equal to the
original.
Is this expected or a bug?
I was expecting a serialized form of
{"number":null}
which, when deserialized does give me an instance equal to the original.
--a.
