Re: Simple CFC quesiton
Holy Zarquon's singing fish! I absolutely LOVE it when we get into these discussions where the "you should never..." starts coming up. The only true generalization is that ALL GENERALIZATIONS ARE FALSE. It is not good to be in the habit of referring to the form scope in your CFC's. That does not mean that you should NEVER do it though. It sometimes fits in really nicely with what you're trying to accomplish. If that's the case, then by all means refer to the form scope in your CFC's. I do agree though, that it's not a good idea in most cases. Sorry, I know the OP had nothing to do with this specific argument, but you all know by now that I'm gonna pitch a fit just about every time I hear someone telling people they should "never" or they should "always" do x or y or z, or even N. --Ferg Oh by the way, you should NEVER step out in front of a bus traveling at high speed and it's ALWAYS a good idea to ensure that your firearm is unloaded before cleaning it. I just felt I needed to throw this in as a preemptive strike at those who are going to say my "no generalizations" argument is wrong. Exceptions abound...

RE: Simple CFC quesiton
As Barney said they are the same in most cases - but there is one caveat.
A "key" in a structure can actually contain a non-standard variable name
(for example foo['11234']). Such a key name will evaluate as YES using
structkeyexists(foo,'1234') and throw an error for "isDefined('foo.1234')".
As it happens I wrote a blog just today on this very issue.

Re: Simple CFC quesiton
No. Most of the time they'll be functionally identical, but the
former is what you want to use in nearly all cases. It's more
performant, far less ambigious, and more clearly communicates what
you're doing. For example isDefined("arguments.imageName") will
return true if you have a URL variable named "arguments.imageName".
