How can I verify and solved that?

If I had to guess, I would bet the empty "results" array literal is the problem.

JsonTextParser throw FormatException when the format is good..

I use this code:

JsonTextParser pars = new JsonTextParser();
JsonObject obj = pars.Parse(XXX);

When the XXX equals to:

{
"responseData": 
	{
	"results":[],"cursor":
			{
			"moreResultsUrl":"http://www.google.com/search?oe\u003dutf8\u0026ie\u003dutf8\u0026source\u003duds\u0026start\u003d0\u0026hl\u003den\u0026q\u003d%D7%90%D7%97%D7%9C%D7%94+%D7%91%D7%97%D7%9C%D7%94+%D7%91%D7%92%D7%A8%D7%A0%D7%93+%D7%A7%D7%99%D7%99%D7%9E%D7%9F"
			}
	}, 
"responseDetails": null, "responseStatus": 200
}

And the exception is:

    System.FormatException was unhandled by user code
      Message="Cannot parse a value."

I'm no expert in json but its seems like a valid json format. And I maybe think its that null, but then it would throw different exception, right?
