We have a CFM system that works 100% for most of the users except a few (less than 10 out of 3000+ users). All users can login without a problem and session variables be set. The login page then send them to the dashboard. We then use the SessionID, among other factors, to encrypt the URL string. However for the 10- users, when they reach the dashboard, we get the error Element SESSIONID is undefined in SESSION The only resolution we have to far is for them to close the browser entirely then start from scratch. Everyone else is working fine. Sure enough, the session struct dump has no SessionID. I know that the sessionid is basically AppName + CFID + CFToken. How can I recreate the SessionID without sending them back to the login or losing the already set session variables? session coldfusion coldfusion-9 sessionid share|improve this question asked Oct 14 '13 at 12:24 SollyM 5991617 When you dump the session scope, what is there? –Dan Bracuk Oct 14 '13 at 12:43 Well from my side everything is fine. But from the users side, every other variable we set after login is there... There is no CFID, CFToken or SessionID. However there is a URLToken that has the value CFID=3876607&CFTOKEN=26913357 –SollyM Oct 14 '13 at 13:53 Are you using J2EE sessions? Do you have any code that does something like structDelete(session, 'sessionid') or anything like that? –Sean Coyne Oct 14 '13 at 14:17 I have a code that deletes the session, then expire the other variables. <

Is Always Created Even If OnSessionStart() Fails By Ben Nadel on March 19, 2009 Tags: ColdFusion Every now and then, in very rare, seemingly random ways, I'll get funky SESSION errors in my ColdFusion applications. Generally, I'll get an email (I email myself errors) that says something like:Element USER is undefined in SESSION.This error will be in some part of the application that the user could http://stackoverflow.com/questions/19360207/element-sessionid-is-undefined-in-session-cf9 not possibly have gotten to had they not already been logged in and clicking around. Meaning, there is no way that the SESSION object would not have been fully initialized at that point in the code.I have never been able to debug this problem. In fact, I've never even been able to http://www.bennadel.com/blog/1535-coldfusion-session-is-always-created-even-if-onsessionstart-fails.htm duplicate the error after I see it come in. Last night, however, I was thinking about session management and it suddenly occurred to me that I am not exactly sure what happens if something in the OnSessionStart() event handler fails. Meaning, if the OnSessionStart() event handler throws an error, does the session get created?To test this, I set up a simple Application.cfc component with a faulty OnSessionStart() event handler:
