Richard Ambridge updated JBRULES-2319:
--------------------------------------

    Description: 
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.

And set the environment as STREAM,
        conf.setOption( EventProcessingOption.STREAM );

and then have a rule:

package com.sample
 
import com.sample.DroolsTest.Message;
global java.util.ArrayList data;
 
declare Message

end

	then

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.
