------------------------------------

             Summary: Allow disabling xwork creating null objects on a property level
                 Key: WW-4203
                 URL: https://issues.apache.org/jira/browse/WW-4203
             Project: Struts 2
          Issue Type: Improvement
          Components: Core Interceptors
    Affects Versions: 2.3.15.2, 2.3.15.1
            Reporter: Jasper Rosenberg
            Priority: Minor


Currently, the ParametersInterceptor sets: ReflectionContextState.setCreatingNullObjects(contextMap, true)

This is great for parameters like "person.name=Phil" since it will create the Person object for you and then set the name.  

However, sometimes you have a converter for a property that will set it as a whole, and you want to make sure that an empty object is never created.  For example, "person=6", where the Person is set by looking it up by id.  Currently, if someone messed with the url and made it "person[x]=6", XWork would end up creating an empty Person object.  (Something along these lines happened to us and I was looking for a clean way to tell XWork to not allow it)

Perhaps the TypeConversion annotation could be extended to support this as an additional flag.
