Re: [rules-users] simple subtraction in drools 5.3 fires rules

I am very sorry for all of my nonsense. My Drools was for some reason having an issue with the ruleflow-group and after I removed it my first rule behaved as yours and fired when it shouldn't have. I know you are probably just going to stick with version 5.4 but if you put a space between the "-" and the number so your rule looks as follows: rule "DummyRule" when d1 : Dummy() d2 : Dummy(y2 == d1.y1, (x1 == (d1.x2 - 150) || x2 == (d1.x2 - 150))) then System.out.println("Rule DummyTest fired"); end it should work in Drools 5.3 (At least for me it did). -- View this message in context: http://drools.46999.n3.nabble.com/simple-subtraction-in-drools-5-3-fires-...
