Thanks... For some reason I should have known that :) Phillip

If you need to duplicate instances of a CFC you will need to write your own clone() method. One side comment: since locking issues for protection of memory integrity are no longer a problem in CFMX you probably don't need to make a duplicate of the application scope (which became a common practice in CF 4.5/5). > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of Phillip Cave > Sent: Tuesday, October 21, 2003 2:07 PM > To: [EMAIL PROTECTED] > Subject: [CFCDev] Duplicate() and CFCs > > > > Hello. > > I'm working with a component that is stored in application scope.
