Baz,
That's actually just the way that onMM() works.
Firing a method from inside a CFC won't trigger the onMissingMethod()
call if it doesn't exist. Only calls from outside the instance, and
as you put it, on the 'this' scope fire the onMM.
The only workaround is to use a this.methodname() approach to fire the onMM.
