My guess would be that the Focus is in MAIN (or some other module that you might have defined) and
not in STATE-CLEANUP where the fact resides (I am assuming that the fact
resides in STATE_CLEANUP since that is where the rule that caused the error
resides). Do a (watch focus) to see where the focus is at the
time of the error.

Subject: JESS: Fact object not in
working memory error
Hello,
I get the following error when trying to execute the code:
(defrule STATE-CLEANUP::Clean2 remove all facts
generated for a pid
(declare (salience -508))
?f1 -
(MAIN::domain-state-req-cleanup(pid ?pid))
?f2 - (STATE-PROCESSING::valid-action(pid
?pid))
=
(modify ?f2 (object nil))
(retract ?f2)
)
The stack trace of the error is:
Caused by: Jess reported an error in routine modify
while executing (modify ?f2 (object nil))
while executing defrule STATE-CLEANUP::Clean2.
Message: Fact object not in working memory
(STATE-PROCESSING::valid-action (oid 17449694) (pid gen113) (object
Java-Object:fleetcycle.domain.es.taskCardAssignment.TaskCardGroupAssignment)

removeTaskCardGroupAssignment) (allowed TRUE) (parentState nil)
(validationErrors nil)).
