> If I create the sample project from Eclipse, and modify DroolsTest to contain:
> KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
> kbuilder.add(ResourceFactory.newClassPathResource("Sample.drl"), ResourceType.DRL);
> KnowledgeBuilderErrors errors = kbuilder.getErrors();
> KnowledgeBaseConfiguration conf = KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
> conf.setOption( EventProcessingOption.STREAM );
>        
> KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase( conf );
> kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
> StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
> KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test");
> 		
> 			
> ArrayList<Message> a=new ArrayList<Message>();
> Message a1=new Message(); a1.setId(1); a1.setMessage("mesC:7"); a1.setStatus(Message.HELLO); a.add(a1);
> Message a2=new Message(); a2.setId(2);a2.setMessage("mesC:8"); a2.setStatus(Message.HELLO);a.add(a2);
> ksession.setGlobal("data", a);
> 	        
> 	        
> 	Message message = new Message();
> 	message.setId(3);
> 	message.setMessage("Hello World");
> 	message.setStatus(Message.HELLO);
> 	ksession.insert(message);
> 			
>         Message message2 = new Message();
> 	message2.setId(4);
> 	message2.setMessage("mesC:7");
> 	message2.setStatus(Message.HELLO);
> 	ksession.insert(message2);
> 	ksession.fireAllRules();
> 	logger.close();
> and then have a rule:
> package com.sample
>  
> import com.sample.DroolsTest.Message;
> global java.util.ArrayList data;
>  
> declare Message
> 	@role( event )
> end
> rule "Hello World"
> 	when
> 	    a : Message(id==4)
> 		m : Message(id!=a.id, message==a.message) from data
> 	then
> 		System.out.println( "a is:"+a+" m is:"+m ); 		
> end
> The result is:
> a is:Message:[4] msg:mesC:7 m is:null
> Notice, m is NULL
> if you change this to fact based,  m will contain the correct value.
