If you do not specify the scope of the variable, according to the docs, CF will search for it in the following order (this is called the order of precedence):
Other scopes always need to be scoped:

I'm not sure if this is the case in CF8 but in earlier versions, that precedence checking happens within a CFC as well. it doesn't just stop with the variables and this scope, it continues on to form, url, cookie, etc...

I'm not sure what you mean by that?? The form, url and cookie scope are in the list... It's just the order that ColdFusion looks at your variable if you don't scope it.

I think what barrry.b was trying to say is that CFCs work in a slightly different fashion than a standard cfm template, as far as order of precedence is concerned. You have function-local variables (those initialized with the 'var', and do not have a scope prefix) that are always first, even over the VARIABLES scope. There is also the THIS scope within CFCs, though I am not sure of their scope precedence location off the top of my head (I never use 'em).

This THIS scope that everybody is referring to.. is this used by anyone... this?? ;-) Sorry.. could resist!

Yes, I use it on some vars in my CFC's. When I explicitly want to access the var directly from outside the CFC.I useit for instance with a global logging mechanism I implemented based on Log4J.
This is cool.
