Solution have found:
(remove ...) => (doall (remove ...))
Full source of 'retract-fact' function is:
(defn retract-fact [fid]
"Retract fact for given fact-id by removing it from alpha, beta and fact
memory,
and also by removing from conflict set activations, containing this
fact-id"
;;(println [:RETRACT-FACT fid])
(if-let [frame (remove-fmem fid)]
(let [[typ mp] frame
ais (a-indices typ mp)]
(if TRACE (println [:<== [typ mp] :id fid]))
(doseq [ai ais]
(set-amem ai (doall (remove #(= (fact-id %) fid) (amem ai)) ) ))
(retract-b fid (.get =FIDS= fid))
(def =CFSET=
(filter #(not (some #{fid} (:FIDS (second %)))) =CFSET=))
(.remove =FIDS= fid)
frame)))
Thank you very much once more!
Best regards,
Ru
