[rules-users] Avoid caching method results within non fact objects

[rogelio_sevilla1]

Thanks Laune and Greg,

Yes, I'm pretty positive that the amount of facts are the real problem in my
situation. Currently I have only 3 rules, and the first one is in charge of
creating the previous state from a current fact in case it has not been
created.

If the session receives a current fact for the first time, this rule creates
the previous state object so it can be updated within other rules.

I have something like this (just a example, sorry for typos):

rule "State Generator"
when
  $currentFact : CurrentFact()
  not PreviousFact(id == $currentFact.id)
then
  PreviousFact previousFact = new PreviousFact();
  previousFact.cloneThis($currentFact)
  insert(previousFact)  <-- this takes a lot of time
end


That's why I would really like to avoid inserting these states within the
working memory. When I started storing them in the Wrapper Hash, the
fireAllRules went from 80 seconds of execution to 7 seconds. 

Thanks a lot in advance for your advice.
