In this line: (if TRACE (do (println [:OFACTS (count ofacts)]) (clojure.stacktrace/e)))
the StackOverflowError must be occurring in the evaluation of ofacts. The error breaks out of the evaluation, preventing (clojure.stacktrace/e) from being evaluated. The error sends you back to the Clojure repl prompt, as you showed: StackOverflowError clojure.lang.RT.nth (RT.java:764) rete.core=> Here, at the "rete.core=>" prompt after the error, is where you want to call (clojure.stacktrace/e). - Bruce On Fri, Nov 8, 2013, at 06:10 AM, Jim wrote: > On 08/11/13 10:46, ru wrote: > > > > I am afraid, that I am not sure where to put (clojure.stacktrace/e) to > > make it work :( > > Or, may be this is not an exception? > > use (clojure.stacktrace/e) after the exception has been thrown to get > some more information than just a line.
