A note about your second OnRequestStart method (with the call to OnApplicationStart) – I get an error when I set a returntype=”void” and then attempt to return true. The error says:

“Void functions must not return any values. ”

Not a big deal. Just seems to be a little typo.

Simon,

What are the implications of forcing a onApplicationStart() on current threads/processing that may be occurring at the sametime? Will the processing/data be dumped midway?

@Simon: I am in a shared hosting environment, probably with sandbox security on, using CF 8 (not 8.0.1 though) and onError method just doesn’t work. Any error generated by the application shows standard CF error page with the following text:

” java method security exception.
A security exception occurred while invoking java method on a “java.lang.Class” object. MethodName is getName. Possible cause: createobject function and cfobject tag are disabled in the security sandbox or you are trying to create a class in the coldfusion package and that is disabled. ”

It has nothing to do with createObject or cfobject, any error generated even by a simple cfm page shows the same info.

Trying to dump Arguments scope of the onError function I receive 2-element struct with “exception” key filled with strange “[undefined struct element]“.

I’d appreciate your opinion, is it some sandbox strange behavior, or just have to change my hosting provider?

@phillip it really depends upon what you want the onError function to do. If you want it to stop page processing when an error occurs, then a cfabort is fine, otherwise it is perfectly OK to remove it.

Good explanation of the properties and methods available in Application.cfc and how to use them…am studying for the cf8 certification and this is a good resource…
