George,
The answer is yes, but in your case it is no. The reason being is that if you are using DataMgr.cfc and have made changes then yes, this has to reinitialised for the changes to take effect. So in your case http://mydomain/?updateapp=true when you have made changes will solve that problem for you. Andrew Scott Senior Coldfusion Developer Aegeon Pty.

Then you can use Application.surveyDAO anywhere in you application On 6/7/07, Andrew Scott < <mailto:[EMAIL PROTECTED]> [EMAIL PROTECTED]> wrote: Looks like Peter got to youJ If you set the Object up in onApplicationStart, there is no need and I mean this!! No need to copy the Application.surveyDAO to the request scope. I would really like to know who is teaching people to do this, can you imagine 1000 users hitting the application and how many extra ram is wasted by such a method.. Peter might like doing this and wasting valuable resources, but it should not be a practice taken upon. If you want to email me your application.cfc, I will modify it and get it to work for you.
