Re: [rules-users] Overriding default evaluators

That may be how its supposed to work, but it does not. PackageBuilderConfiguration#buildEvaluatorRegistry selects properties from 'chainedProperties' from the two collections of properties -- the drools default and the scala extensions -- into a single map. It then adds the evaluators from that combined map, which is now intermingled so the add order is undefined. My workaround was, after the registry is first created but before any drls are parsed (hack alert): def registerScalaEvaluators(kbuilder: KnowledgeBuilder) { val kbuilderConfig = kbuilder.asInstanceOf[KnowledgeBuilderImpl].getPackageBuilder.getPackageBuilderConfiguration val chainedProperties = kbuilderConfig.getChainedProperties val evaluatorRegistry = kbuilderConfig.getEvaluatorRegistry val scalaEntries = new java.util.HashMap[String, String] chainedProperties.mapStartsWith(scalaEntries, EvaluatorOption.PROPERTY_NAME+"scala_", true) for (className <- scalaEntries.values) { evaluatorRegistry.addEvaluatorDefinition(className) } } -- View this message in context: http://n3.nabble.com/Overriding-default-evaluators-tp441342p442360.html Sent from the Drools - User mailing list archive at Nabble.com.
