Thanks Jeffrey, The problem is not in logging a user in... the action I have is doing that just fine. The problem is when you try to detect if a user calling the login action is ALREADY logged in or not (in this case, we have guest users coming in from another site).
I want to make it so if the user is already logged in, it does not log them in again. However, when I test the User returned in the doperform() method in my login action, it is always NULL. It appears that something up the chain is wiping the User object and the session. --Nathan -----Original Message----- From: Jeffery Painter [mailto:[EMAIL PROTECTED] Sent: Thu 1/31/2008 1:08 PM To: Turbine Users List Subject: RE: user is nulled out on login attempt I had used Turbine to build a prototype of an electronic health record system. I can't remember if we were using Turbine 2.1 or 2.2 but I have my custom login action is here: http://office.kiasoft.com/viewcvs/viewcvs.cgi/agrippa/WebRoot/WEB-INF/src/edu/ncsu/csc/agrippa/modules/actions/AgrippaLoginUser.java?rev=1.1.1.1&content-type=text/vnd.viewcvs-markup Maybe that will give you some insight... it worked last time I ran the code but that was Dec 2006...
