[rules-users] Execution problems with (or and (and

Hi, I have a problem with this execution : rule "Your First Rule" when (or not Venue() (and v:Venue() l:ListeSousVenue() p:Param())) then System.out.println("OK - 1"); end rule "Your Second Rule" when (or not Venue() (and p:Param() l:ListeSousVenue() v:Venue())) then System.out.println("OK - 2"); end In my WM, I have a Param and a ListeSousVenue but no Venue But after execution, I have just this result : "OK - 1" Why the second rule doesn't execute ?
