[jira] Commented: (CXF-2916) unmarshalling the JSON of a subclass fails when a field value is null

Hi Andrew 

Can you please attach CXF-2916-jettison.patch to http://jira.codehaus.org/browse/JETTISON-89, if possible with a simple
Jettison test ? This will make if feasible to start talking about say Jettison 1.2.1. We can't really depend on 1.3-SNAPSHOT, this would be a major release, with some major fixed/enhancements and it is unlikely to happen in the short term. 1.2.1 is more realistic.

In meantime, the only thing you can do in CXF is to register a custom provider extending JSONProvider and override createReader(). Delegate to the superclass first and then wrap the returned reader in your own. Then somehow deal with "null" sequences...

> Unmarshalling the JSON :
> {"@xsi.type" : "subClassTest", "id" : "10000000", "name" : null }
> should give an instance of SubClassTest.class and the value of the field name(which is a String) should be null, but with the current implementation the value of the field name is String "null" .
> This happens only in the case of unmarshalling JSON to a subclass.
