Sigh. The behavior of (definstance) in 4.1b4 has changed, hasn't it? I
see from the documentation a couple of conflicting statements:
* Section 3 Jess Function Guide
(retract): Retracting a definstance fact will result in an
implicit call to undefinstance for the corresponding object (the
object will no longer be pattern-matched.) [ this is the
behavior seen in 4.1b3, under which our software performs
correctly ]
* Section 7.7.2
"Once a definstance construct has been issued, there will always
be a fact on the fact-list representing that object (until the
'clear' command is issued.)" [ this contradicts the definition
of (retract) ]
I suppose I could work around this issue by not using
'defclass/definstance' and writing my own "shadow" deftemplates, but
gosh...
Any clarification would be appreciated. Thanks much.
Regards,
