Mon Aug 8 19:46:26 EDT 2011

Hello, I've tried searching forums but haven't had any luck with this. The
error log is giving me this:

<2011-08-08T16:43:09> 	2120			
 Error: Session has expired or is invalid. Please log in again.

And here is my source. I'm using a single layout and dynamically changing
the map, then copying it to the session repository and pointing my browser
frame to it. Not sure why i'm getting the invalid session errors...Logs show
me properly getting a session, finding the initial web layout resource, then
saving the new resource.
