Hello basulasz,
That code works fine. Have you tried to run that in new project.
Perhaps your ArrayList store smth which can't be casted to object. If exactly that code u shown didn't work (emply arraylists) that I recomment to re-register asp.net 2.0 calling aspnet_regiis,exe - i

b> Hi Michael;
b> b> There is noting interesting in the code, just creating arraylists and
b> defining values like below
b> b> ArrayList al_RecNo = new ArrayList();
b> ArrayList al_Mess = new ArrayList();
b> ArrayList al_Type = new ArrayList();
b> Session["_al_RecNo"] = (object)al_RecNo;
b> Session["_al_Mess"] = (object)al_Mess;
b> Session["_al_Type"] = (object)al_Type;
b> In this case does session state make any sense? For example on my
b> project there is no definition in web.config file about SessionState.
b> But on web server the SessionState is configured as InProc and
b> session variables is stored on web server's local sql database. What
b> should I do in this case? Should I configure my project to store
b> variables on local sql server? Is it not possible to store arraylist
b> or datatable object on session without storing variables on sql
b> server?
b> b> Thanks...

Hello basulasz,
could you demonstrate your code?
Seems that you are using the outproc session state, where your object
in session must be serializable
