[rules-users] why loop fire with no-loop is true?

*i expect the result is 530,and define the "no-loop=true" in the rules ,but result is 460,why?* * -------------------------------------------------------------------------------------------------------------------------------------------------- * my java test code: package org.sample; import org.drools.KnowledgeBase; import org.drools.KnowledgeBaseFactory; import org.drools.builder.KnowledgeBuilder; import org.drools.builder.KnowledgeBuilderError; import org.drools.builder.KnowledgeBuilderErrors; import org.drools.builder.KnowledgeBuilderFactory; import org.drools.builder.ResourceType; import org.drools.io.ResourceFactory; import org.drools.logger.KnowledgeRuntimeLogger; import org.drools.logger.KnowledgeRuntimeLoggerFactory; import org.drools.runtime.StatefulKnowledgeSession; public class SalesTest { public static final void main(String[] args) { try { // load up the knowledge base KnowledgeBase kbase = readKnowledgeBase(); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test"); // go !
