Right now contentType isn't dynamically resolved, please register an
issue and I'll add such option to JSONResult so you will be able to
specify contentType via <param/> tag, eg.
<result type="json">
<param name="contentType">${resolveContentType}</param>
</result>
and the action's resolvedContentType method will be called to obtain
valid contentType
Happy New Year :-)
