I think its because you have variables.componentPath in the string to go find it. On application start this wont exist.

[cfaussie] Re: Application object
Yes, Andrew's method of restarting the application is a good one. Beats restarting CF. Mind you be careful as to what url you need to pass the application to cause a restart, obviously if this got in the wrong hands. You can have a totally separate page if you wish, that takes some type of password. http://www.site.com/appRestart.cfm This could ask for a password and restart the app by calling the Application methods Andrew used. This way the method of restarting your app doesn't end up in browser caches etc, at least not the password bit.

As Dale said, this can have undesired results if used in the wrong situation. However in my case, and not everyone is the same in this regard. But I only use that method on my development server, and prefer to have a temp file that is deleted when it is executed to restart the application when changes have been made to the Application.cfc which is very rare for my current clients work.

[cfaussie] Re: Application object
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.

any code inside the OnApplicationStart function will only run the first time the application is run. So if you put in a new CreateObject() you will need will need to do the ?updateapp=1 If you change a CFC that has already been created and stored in the APPLICATION scope, you will also need to do updateapp=1 as the old version will still be there.

[cfaussie] Re: Application object
Thanks Andrew and AJ. Now I understand - once an object is initialised in OnApplicationStart function then it's available in every page.
