I wouldn't be so quick to dismiss a code problem. I've seen a lot of code in my time that once "worked" that stopped working on an upgrade. It could be the use of a depreciated function or tag, or simply code that worked due to issues in the CF engine at the time--but which shouldn't have run. Also, I believe I remember reading CF8 changed some behavior of nested <cfoutput>/<cfloop> tags in CF8, but I can't recall exactly what I read. Finally, I will say don't overlook the obvious. If a user clicks on a link/button multiple times, unless your script explicitly prevents the behavior, the server will process the request multiple times. This is the most common cause of "duplicates" that I've seen. -Dan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Get involved in the latest ColdFusion discussions, product development sharing, and articles on the Adobe Labs wiki. http://labs/adobe.com/wiki/index.php/ColdFusion_8 Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:293863 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
