the success result should look something like..
<action name="yourAction"
class="org.apache.struts2.portlet.dispatcher.YourAction">
<result name="success" type="json">success.jsp</result>
<param name="root">jsonResult</param>
</result>
/**success.jsp would have logic to accept a ajax response from YourAction*/
the behaviour should be consistent between supplied params in xml and those
supplied to the annotationTag so i believe you found a genuine bug
to clear the disconnect between 'json' type and no name of json assigned
and for a complete testcase can you supply struts-plugin.xml (should look like)
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd";>
<struts>
<package name="json-default" extends="struts-default">
<result-types>
<result-type name="json"
class="com.googlecode.jsonplugin.JSONResult"/>
</result-types>
<interceptors>
<interceptor name="json"
class="com.googlecode.jsonplugin.JSONInterceptor"/>
</interceptors>
</package>
</struts>
JSONResult.java states
* <pre><!-- START SNIPPET: example -->
* <result name="success" type="json" />
*/
public class JSONResult implements Result {
thanks for working on a holiday!
