Ok, i will try. For information, I found a workaround : This two rules work : rule "3 Rule" when (or (and v:Venue() l:ListeSousVenue() p:Param()) not Venue() ) then System.out.println("OK - 3"); end rule "4 Rule" when (or (and p:Param() l:ListeSousVenue() v:Venue()) not Venue() ) then System.out.println("OK - 4"); end -- View this message in context: http://www.nabble.com/Execution-problems-with-%28or-and-%28and-tf4352997....

Folks, Using 4.0.GA I need to have the following logical chain: Having facts F1(), F2(), F3(), F4() I need a rule to be fired when (F1() and F2()) or (F3() and F4()) condition is true, so made a rule: when (or (and F1() F2() ) (and F3() F4() ) ) then ... But it doesn't execute correctly. F.e. it fires when F1() and F4() are inserted although F2() and F4() are not! Please advice is it my incorrect syntax, or a bug....?

Ok, can you please attach a selft contained test code and re-open the JIRA? Thanks, Edson 2007/8/31, vdelbart <delbart.v(a)mipih.fr&gt;: -- Edson Tirelli Software Engineer - JBoss Rules Core Developer Office: +55 11 3529-6000 Mobile: +55 11 9287-5646 JBoss, a division of Red Hat @ www.jboss.com

vdelbart, Thanks for providing the test case. I just executed it and saw the problem. It is a bug in the WorkingMemoryFileLogger, not the engine. I will fix the file logger, but meanwhile you can turn it off to make your application work.

Hi group, Currently I have to use eval to access to lower lever of an attribute. For example: rule "test rule" when $person: Person () eval (($person.getContact() != null) && ($person.getContact().getEmail() == null)) then System.out.println ("Email address is missing") end Is there anyway not to use eval. I would like to do something like this: $person: Person ($contact: contact != null, $contact.getEmail() == null) but it throws errors Thanks, Tim
