[rules-users] Get previous fact from working memory.

[Vincent Legendre]

Hum, rigth ...
You want the last to be false ?

may be something like that (ignore the type first to get the last, then 
test it in a eval)

rule "check_agains_last"
when
      $e1 : Event (eventType == Event.EventType.EVENT1)
      $e2 : Event (this before $e1)
      not Event (this after $e2)
*      eval ($e2.getEventType() == Event.EventType.EVENT2)*
then
     ...
end


But to me this rule is too complex according to what it tells ... You 
should implement the chaining via the listener.
