Yup. All function-local variables in a CFC should be var scoped. CF
9 did introduce the "local" scope inside of CFC methods, so doing
this:
<cffunction name="myFunction">
<cfset local.myVariable = "foo" />
</cffunction>
is functionally equivalent to doing:
<cffunction name="myFunction">
<cfset var myVariable = "foo" />
</cffunction>
So while there are now 2 ways to declare a variable as local to a
given function (assuming you're on CF 9), the requirement still
remains that you do need to scope these variables properly in order to
avoid leakage.

I have failed as much as I have succeeded. But I love my life. I love
my wife. And I wish you my kind of success.
