Howard M. Lewis Ship commented on TAPESTRY-2619:
------------------------------------------------

I'm having trouble reproducing this in 5.0.15-SNAPSHOT.

For example, the DatePicker does exactly this:

   JSONObject onParse()
    {
        String input = request.getParameter(INPUT_PARAMETER);
        JSONObject response = new JSONObject();

        try
        {
            Date date = format.parse(input);

            response.put(RESULT, date.toString());
        }
        catch (ParseException ex)
        {
            response.put(ERROR, ex.getMessage());
        }

        return response;
    }


And, I've verified using FireBug, it works correctly.
