Rule that operates on 2 facts uses the same fact for both arguments
-------------------------------------------------------------------
Key: JBRULES-382
URL: http://jira.jboss.com/jira/browse/JBRULES-382
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Reporter: Geoffrey De Smet
Assigned To: Mark Proctor
Priority: Minor
Fix For: 3.0.3
Attachments: JBRULES-382.zip
According to a reply on the thread "[drools-user] A few beginner drl questions" in the user mailing list, this is a bug.
Rule:
rule secondRule
when
$lesson1 : Lesson($teacher : teacher, $group : group, $timeslot : timeslot)
$lesson2 : Lesson(teacher == $teacher, group == $group, timeslot == $timeslot)
then
System.out.println("secondRule: " + $lesson1 + " with " + $lesson2);
end
gives an output where both lessons are the same fact:
secondRule: 0: teacher1 + group1 with 0: teacher1 + group1
I 'll attack a zip of my m2 configured app. To repreduce:
- mvn install eclipse:eclipse idea:idea
- Run net.sf.tabudrool.app.TabudroolApp
- Click "Load unsolvedSchedule1.xml"
- Click "Plan schedule"
You'll get this output, which proves that the same lesson is used both facts of the rule:
