Lukasz Lenart commented on WW-4733:
-----------------------------------
A pram used when no param was defined, e.g. {{<result
name="success">/WEB-INF/index.jsp</result>}} in this case {{location}} will be
used as it is defined as a default param, it's the same as
{code:xml}
<result name="success">
<param name="location">/WEB-INF/index.jsp</param>
</result>
{code}
> No default parameter defined for result [json] of type
> [org.apache.struts2.json.JSONResult]
