Re: [rules-users] parsing error using accumulate

Hi! I'm integrating Weka with Drools v.4 and I have a parsing error while trying to read the following DRL rule: rule "calculate average" when $inst : Instance() $media : Double(double value > 50000) from accumulate($value : inst.classValue() average($value)) then System.out.println(media ); end I have the following error: org.drools.compiler.DroolsParserException: Unknown error while parsing. This is a bug. Please contact the Development team. at org.drools.compiler.DrlParser.compile(DrlParser.java:180) at org.drools.compiler.DrlParser.parse(DrlParser.java:61) at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java :158) at com.sample.DroolsTest.readRule(DroolsTest.java:67) at com.sample.DroolsTest.main(DroolsTest.java:24) What I am doing wrong?
