Yes Sean, this summary is correct.

However, this solution along with some issues I was having in another
thread with cfsavecontent and cfoutput. Until the last couple of days,
I was under the impression that CFCs were entirely their own
encapsulated entities, assuming you followed best practices by not
using the "this" scope, etc. However, what I've seen over the last
couple days is that page-level settings "leak in" to the CFC "space."
Here are a couple specific examples in case you haven't seen the other
threads:

1) If I have cfsetting enablecfoutputonly="yes" at the top of my
calling code, I need to put cfoutput around my cfsavecontent syntax
within my CFC methods. Otherwise nothing is saved in the cfsavecontent
variable.

2) If I'm uploading a file, the CFC apparently has access to the form
scope in some way. If I pass in a literal string called
"form.uploadFile" then the CFC can somehow "reach in" to the form
scope of the calling page and get the file.

My overriding question to this is: Is it acceptable to have elements
of the calling code available automatically to the CFC space?
"Acceptable" is probably not the best word to use, but I can't think
of a better one. The way I always thought of CFCs is that I need to
explicitly tell it what I want it to do and/or explicitly pass in any
value I want it to have rather than have it pull in the calling page
settings.

Does that question make sense? Any insight is appreciated.

Regards,
Dave.
