Yep... for every component, there's at least 3 scopes:
variables
this
super
When you call createObject("component","foo.path.to.my.Component"),
you're having ColdFusion create you an instance of a component and it
has it's very own set of scopes. In order to give it access to share
data between scopes you have to code it to get data from any other
scope, or any other component.
When you are writing a cffunction you have to consider two other
scopes as well. Function-local scope and the arguments scope. Inside
every component function, be sure to use the var keyword i.e. <cfset
var someFoo = "foo"/> so that your variable will exist in the
function-local scope (or you could just use the arguments scope,
which I often do). If you don't, your variables will get put into the
variables scope instead of being cleared out and reused as available
memory after the function finishes executing.
