I've noticed a strange problem when using cffile in a custom tag that I hope
someone might shed some light on. To help explain myself you can run the two
pages below, one is the custom tag strange.cfm, the other a form page.
Within strange.cfm CALLER.FileExisted exists without me setting it (the
cfparam and cfset are commented out at this point). Yet when I try and
reference VARIABLES.fileExisted in the calling page I get an error. Using
cfparam doesn't help, which I find strange, but cfset does what it should
do.
This was run on CFMX with no updaters and now at work with CFMX and updater
2.
Anyone have an explanation?
