The problem is when I try to bind the value of the external to ?tf, the
pattern never match's. The following never match's, even though there are
facts which it should fire on. externalObserver is bound to an external
java.awt.TextField.
( dependency ( subject ?addressID ) ( externalObserver ?observer ) )
I want to put external global's in facts, retrieve them, and use them.
