             Summary: Have ObjectFactory buildResult obey ParameterNameAware restrictions for a Result
                 Key: WW-4144
                 URL: https://issues.apache.org/jira/browse/WW-4144
             Project: Struts 2
          Issue Type: Improvement
          Components: Core Actions
    Affects Versions: 2.3.15.1
            Reporter: Jasper Rosenberg
            Priority: Minor
             Fix For: 2.3.16


com.opensymphony.xwork2.ObjectFactory#buildResult(ResultConfig, Map), injects all of the resultConfig parameters into the result after it has been built.  

However, I'd like to be able to have my Result implement ParameterNameAware, and then have buildResult obey its acceptableParameterName() result so I can filter out what parameters can be injected.

I'm sorry I don't have a proper patch, but it is a very small change.  Only call setProperty on the result if it is not ParameterNameAware, or it is and the parameter name is acceptable.

{code:java} 
if ((!(result instanceof ParameterNameAware)) || (((ParameterNameAware) result).acceptableParameterName(paramEntry.getKey()))) {
    reflectionProvider.setProperty(paramEntry.getKey(), paramEntry.getValue(), result, extraContext, true);
}
{code}

I have been running a Struts 2 app for 6 years with this change in place.  Just getting around to suggesting it as a patch :)

It does also look like the documentation for ParameterNameAware would need to be updated to reflect that it can also be used for results, not just actions.
