[rules-users] Drools firing wrong rules

Hi everyone, I have a couple of rules, I just want to show a message when one of the fields is null and heres my code: 21. | rule 'rule1' 22. | salience 9990 23. | when 24. | Cuscar(bgm.size > 0 && bgm[0].c1001== null ); 25. | then 26. | logger.log("Rule 1 activated"); 27. | 28. | end 29. | 30. | rule 'rule2' 31. | salience 9970 32. | when 33. | Cuscar(bgm.size > 0 && bgm[0].c1004== null ); 34. | then 35. | logger.log("Rule 2 activated"); 36. | 37. | end And here's the result: Scenario #1 http://drools.46999.n3.nabble.com/file/n3160376/debug2.jpg with this values when I call fire all rules I dont get any message (its ok because none of the elements is null) Scenario #2 http://drools.46999.n3.nabble.com/file/n3160376/debug1.jpg with this values when I call fire all rules both rules are fired so i get both messages "Rule 1 activated" and "Rule 2 activated" (Incorrect - it should only fire rule number 1 cause only the element c1001 is null) Scenario #3 http://drools.46999.n3.nabble.com/file/n3160376/debug3.jpg with this values when I call fire all rules I dont get any message (Incorrect - it should activate rule number 2) This is my model: http://drools.46999.n3.nabble.com/file/n3160376/rules-drools-model-1.0.0-... rules-drools-model-1.0.0-SNAPSHOT-jar-with-dependencies.jar Can anybody help me please?, I dont know what am I doing wrong, thank you very much :) .... -- View this message in context: http://drools.46999.n3.nabble.com/Drools-firing-wrong-rules-tp3160376p316...
