[rules-users] Inconsistent behavior of a rule

See attached DRL. input is: condFt="supportedValue" I have a rule with the following 'when' part which will not hit, though it should: $supportFT: supportFT() condFT(value == $supportFT.getValue()) $conclusion: testInferred() while the following one will hit, even though the two seems equivalent: $supportFT: supportFT(value == null || value !=null) condFT(value == $supportFT.getValue()) $conclusion: testInferred() another one that seems equivalent that will hit: $supportFT: supportFT() supportFT(value == $condFt.getValue()) $conclusion: testInferred() Not sure if it is indeed a bug, or a misuse on my part, but I can't understand why the first rule will not hit. And even stranger, why the second and third which seems the same will. testInferred3.drl <http://drools.46999.n3.nabble.com/file/n4021003/testInferred3.drl> -- View this message in context: http://drools.46999.n3.nabble.com/Inconsistent-behavior-of-a-rule-tp40210...
