Problem when mixing alpha and beta constraints in a composite constraint ------------------------------------------------------------------------ Key: JBRULES-1472 URL: http://jira.jboss.com/jira/browse/JBRULES-1472 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 4.0.4 Reporter: Edson Tirelli Assigned To: Edson Tirelli Fix For: 4.0.5, 5.0.0-M1 REPORTED BY Jai Vasanth The first case rule "Remove smaller or non-overriden" dialect "java" when L : Response( $r : value && status != "override" ) (Response( value > $r ) or Response( status == "override")) then retract( L ); end breaks down to rule "Rule1" dialect "java" when L : Response( $r : value && status != "override" ) Response( value > $r ) then retract( L ); end and rule "Rule2" dialect "java" when L : Response( $r : value && status != "override" ) Response( status == "override") then retract( L ); end I see that the first rule removes all objects with smaller values and the second one removes all the ones that arent overridden if there exists an object that has an override What I dont understand is, why the second one doesnt have similar behaviour rule "Remove smaller or non-overriden" dialect "java" when L : Response( $r : value && status != "override" ) Response( value > $r || status == "override" ) then retract( L ); end When this rule runs , it should start removing objects with smaller values that are *not* overridden . So if an overridden object exists finally we will be left with 2 objects Response( maxvalue, non override status ) and Response( somevalue, "override" ) When the rule fires now L will take on the first one and the the other object will match the second one since it has an override even though value <= $r . This L should be extracted and we should just be left with the overridden object. But I still seem to be left with both the objects. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
