Have you tried this? I am sure at the current implementation of Jess you
cannot have facts with nested structure like this above. What you can have
though, is somethig like:
Fact:
(message david reply "(i_know (fact A in stack 1))")
Rule:
(defrule test
(message ?who ?action ?content)
=>
(assert-string ?content)
)
It will work as expected, inserting for you new fact:
(i_know (fact A in stack 1))
Hope it helps
Best regards
