Hey,
I don't have much problems between flex sessions and sessions
in a JSP (if that is what you mean).
I would suggest to investigate some time using Blaze-DS
because it will give you a must faster response time then using
JSon.
What is your exact problem using sessions??
Here is a example what I do :
set user_id in a session
FlexContext.getFlexSession().setAttribute("user_id", id);
get it back:
id =
(Integer)FlexContext.getFlexSession().getAttribute("user_id");
get it in a JSP page:
user_id = session.getAttribute("user_id");
