[JBoss JIRA] Created: (JBRULES-2398) Rule not fired when using 'in (0)' condition and another rule with condition ' == null' exists

by Jaroslaw Wosik (JIRA)

Rule not fired when using 'in (0)' condition and another rule with condition ' == null' exists ---------------------------------------------------------------------------------------------- Key: JBRULES-2398 URL: https://jira.jboss.org/jira/browse/JBRULES-2398 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-compiler (expert) Affects Versions: 5.0.1.FINAL Environment: Windows Xp Pro, Java 1.5.07 Reporter: Jaroslaw Wosik Assignee: Mark Proctor When following package is used: package BROKEN_TEST; import pl.wosik.conversion.BrokenTest.Holder; rule "_12" salience 3 activation-group "BROKEN" when $a : Holder(value in (0)) then System.out.println("setting 0"); $a.setOutcome("setting 0"); end rule "_13" salience 2 activation-group "BROKEN" when $a : Holder(value in (1)) then System.out.println("setting 1"); $a.setOutcome("setting 1"); end rule "_22" salience 1 activation-group "BROKEN" when $a : Holder(value == null) then System.out.println("setting null"); $a.setOutcome("setting null"); end Rule "_12" will not be fired even when Holder.value is 0 because some strange interference between it's and rule _22's condition (note that _22 won't be fired as expected). When "Holder(value in (0))" is changed into "Holder(value == 0)" or "Holder(value in (0,9))" or the whole rule_22 is removed rule _12 will be fired. This issue is important as such seemingly strange "in (0)" condition can be generated from a decision table (as was in my case). I will attach a self-contained Test Case. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
