Subject RE: AjaxTag 1.3 support?
Date Mon, 04 Feb 2008 20:43:34 GMT
So, if you have an array of Entity objects, in my case question:

How can I produce?
 {
     "question" : [
         ["1","question 1 text..."],
         ["2","question 2 text..."]
     ]
 }

yes, but the output will depend on what you feed the JSON result.
