How to pass null values in a JSON request

Passing a null value to any Corticon Server using JSON payloads is accomplished by either:

• Omitting the JSON attribute inside the JSON object
• Including the attribute name in the JSON Object with a value of JSONObject.NULL

JSON payloads with null values created by Rules

When Rules set a null value that propagates into the payload of a request, JSON treats the null as follows:

Assume that the incoming payload is...

      Person
        Age  : 45
        Name : Jack

... and that rule processing sets Age to a JSONObject.NULL object.

If JSONObject.toString() is called, the output would look like this:

      Person
        Age  : null
        Name : Jack
