Duplicate parameter while trying to use pattern bound variables or globals in accumulate function ------------------------------------------------------------------------------------------------- Key: JBRULES-1354 URL: http://jira.jboss.com/jira/browse/JBRULES-1354 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 4.0.3 Environment: JDK 1.5.0_13, Ubuntu 7.10 Reporter: Eric Miles Whenever I attempt to reference a pattern bound variable (declared outside of accumulate) or a global from within an accumulate function, I get a "Duplicate parameter" error. Example of pattern bound variable: rule "Test" when $obj: SomeObject() Integer() from accumulate( AnotherObject() , init (int total = 0 ), action ( total += $obj.getValue(); ), reverse ( total -= $obj.getValue(); ), result ( total) ) then System.out.println("HI!"); end The same happens when if I attempt to use a global. Here is an exact stacktrace of the error: org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule name=Daily Core Hours, agendaGroup=MAIN, salience=0, no-loop=false] com/kronos/webta/service/smarttime/rules/Rule_Daily_Core_Hours_0.java (32:1301) : Duplicate parameter $schedOut com/kronos/webta/service/smarttime/rules/Rule_Daily_Core_Hours_0.java (32:1330) : Duplicate parameter $schedIn com/kronos/webta/service/smarttime/rules/Rule_Daily_Core_Hours_0.java (41:1735) : Duplicate parameter $schedOut com/kronos/webta/service/smarttime/rules/Rule_Daily_Core_Hours_0.java (41:1764) : Duplicate parameter $schedIn com/kronos/webta/service/smarttime/rules/Rule_Daily_Core_Hours_0.java (51:2330) : Duplicate parameter $schedOut com/kronos/webta/service/smarttime/rules/Rule_Daily_Core_Hours_0.java (51:2359) : Duplicate parameter $schedIn com/kronos/webta/service/smarttime/rules/Rule_Daily_Core_Hours_0.java (58:2738) : Duplicate parameter $schedOut com/kronos/webta/service/smarttime/rules/Rule_Daily_Core_Hours_0.java (58:2767) : Duplicate parameter $schedIn at org.drools.rule.Package.checkValidity(Package.java:424) at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:364) at com.kronos.webta.service.smarttime.rules.maxiflex.FlowTest.setUpBeforeClass(FlowTest.java:79) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.junit.internal.runners.ClassRoadie.runBefores(ClassRoadie.java:49) at org.junit.internal.runners.ClassRoadie.runProtected(ClassRoadie.java:36) at org.junit.internal.runners.JUnit4ClassRunner.run(JUnit4ClassRunner.java:42) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:38) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
