>> possible to access the variables scope of the calling page from within a CFC?
hang, on. you want to change the CFM variables values from within a CFC, yes? (not the
other way around?)
OK...
keep in mind that Gary'r right - this breaks encapsulation (how does the cfc know that
a particular cfm's variable actually exists or not? sure you wrote it like that but
will it ALWAYS be the case?, etc)
I haven't tried this, but can anyone see anything wrong with passing the cfm's
VARIABLES scope in byValue as a struct? (argh! my VB terms creeping in...) and then
returning the changed struct and assigning them back to the calling pages VARIABLES
scope?
<cfset myNewVars = myCFC.changeVarsMethod("#VARIABLES#") />
<cfset VARIABLES = myNewVars />
changing values byReference (eg a CFC changing SESSION or APPLICATION vars) can be
dangerous because the "blackbox" of a CFC hides what's happening.
but making a copy and changing that (to return back and replace the calling pages'
VARIABLES scope with) seems like a way to do it...
just my 2c worth

PS: as a FYI: in custom tags is the CALLER scope a copy of the VARIABLES scope or a
pointer to it?
