Yasser Zamani commented on WW-4846:
-----------------------------------

I remembered another solution could be unwrapping Spring proxy like something 
like below:

{code:java}
public class FeatureUpgradeAction extends BaseAction implements 
InitializingBean {
private FeatureUpgradeResponse featureUpgradeResponse;
private FeatureUpgradeRequest featureChangeRequest;
public FeatureUpgradeResponse getFeatureUpgradeResponse()
{ return this.featureUpgradeResponse; }
public FeatureUpgradeResponse getUnwrappedFeatureUpgradeResponse()//I added this
{if(AopUtils.isAopProxy(featureUpgradeResponse) && featureUpgradeResponse 
instanceof Advised) {
    Object target = 
((Advised)featureUpgradeResponse).getTargetSource().getTarget();
    FeatureUpgradeResponse ai = (FeatureUpgradeResponse)target;
} }
{code}

{code:xml}
<action name="retrieveStoragePlans" method="retrieveStoragePlans" 
class="featureUpgradeAction">
<interceptor-ref name="cloudStack" />
<result name="success" type="json">
<param name="contentType">application/json</param>
<param name="noCache">true</param>
<param 
name="excludeProperties">errorCode,messageCode,processTime,result,status,statusDesc,title,uniqueId,availableFeatures.featurePlanAsInt</param>
<param name="excludeNullProperties">true</param>
<param name="root">unwrappedFeatureUpgradeResponse</param> <!-- I changed here 
-->
</result>
{code}
