Thanks for ultra fast responses. I guess they went through
AjaxComponentEventResultProcessor :-)
Until I try implementing the processor class, I found a compromise.
return org.apache.tapestry5.json.JSONObject jsonObject = new
org.apache.tapestry5.json.JSONObject(JSONSerializer.toJSON(userData).toString());
I found out that org.apache.tapestry5.json.JSONObject has a constructor with
a String form of a JSON object.
Thanks!
