    Session Errors

    kalvish Newbie

      All,

       

      I'm having the below error. Seems like when I load my page, and let it stay for a few minutes (well below my session timeout of 60 mins) I get this error click on any of my command links on the page. The error is very long, and i'm not sure what to make of it. Can somebody please point me in the right direction? I will greatly appreciate it as I've been stuck on this for sometime!
