Hello,
Thanks for your quick response yesterday. I have implemented the
patches you directed me to, but have run into some new (I believe
related) problems.
Once again, this rule seems to cause the problems
(defrule done-task
(declare (salience -2))
?f <- (task (list ? $?rest))
=> (modify ?f (list $?rest))
)
I think a trace of what happens when this rule fires with the same code
in version 4.44 compared to a trace of what happens with 5.0a5 would be
the best way to explain the problem.
Here it is in version 4.4
FIRE [Defrule: done-task ; 1 patterns; salience: -2] f-283 <== (task
(patient 14173) (visit 14285) (posture 14286) (menu 14287)(list
construct-menu check-counterindications output))
==> Activation: done-task : f-300
==> Activation: twist-counterindicated-by-severe-elevation :
f-300,f-296, f-167, f-245
==> (task (patient 14173) (visit 14285) (posture 14286) (menu
14287)(list check-counterindications output))
;;; other rules fire
FIRE [Defrule: done-task ; 1 patterns; salience: -2] f-300
<== (task (patient 14173) (visit 14285) (posture 14286) (menu
14287)(list check-counterindications output))
==> Activation: done-task : f-302==> Activation: output-routines :
f-302
==> (task (patient 14173) (visit 14285) (posture 14286) (menu
14287)(list output))
;;; other rules fire
FIRE [Defrule: done-task ; 1 patterns; salience: -2] f-302
<== (task (patient 14173) (visit 14285) (posture 14286) (menu
14287)(list output))
==> (task (patient 14173) (visit 14285) (posture 14286) (menu
14287)(list ))
TRUE
Jess>
Now, this is what happens with version 5.0 a5
FIRE 98 done-task f-289
<== f-298 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list construct-menu check-counterindications output))
==> f-341 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list check-counterindications output))==> Activation: done-task :
f-341
;;; no other rules fire
FIRE 99 done-task f-341
<== f-341 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list check-counterindications output))
==> f-342 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list output))
==> Activation: done-task: f-342
;;; no other rules fire
FIRE 100 done-task f-342
<== f-342 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list output))
==> f-343 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list))
==> Activation: done-task: f-343
FIRE 101 done-task f-342
<== f-343 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list))
==> f-344 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list))
==> Activation: done-task: f-344
FIRE 102 done-task f-343
<== f-344 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list))
==> f-345 (task(patient 14173)(visit 14285)(posture 14286)(menu
14287)(list))
==> Activation: done-task: f-345
into an endless loop.
Any input on this problem would be much appreciated
Thanks,
