CFCATCH/CFTRY-CFERROR

[weezerboy]

I am getting this error message when my users attempt to return to my site with an expired SESSION variable.

Element FNAME is undefined in SESSION

I could possibly fix the error but it would be difficult.........

Since I know its going to occur ...

How would I use CFCATCH/CFTRY-CFERROR to catch this error and redirect these users to the login screen?

The isDefined function may be useful. Details are in the cfml reference manual. If you don't have one, the internet does.

It is not really approprite to use try-catch or cferror, as the error is not an exception. I would follow Dan's advice, and do the isDefined test in Application.cfc or Application.cfm.
