[rules-users] RuleFlow and facts

[paf84]

Hello, 

I try to understand how to use Drolls.
It's not the first time i work with rules (i know JRules).
I have a probleme when i execute my ruleflow.
I have some rules which belong to different ruleflow-group.
I have put my ruleflow-group in my ruleflow.

THe probleme is that my ruleflow never execute the "then" part of my rules.


If i delete le ruleflow-group of my rules and i execute the drl file, all my
"then" part are executed.
I think i have a problem to give my facts to the ruleflow...

Is somebody can help me ? 

thx!!

my .java


KnowledgeBase kbase = readKnowledgeBase();
			StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
			KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test");
			// start a new process instance
			System.out.println("init");
			Parametre parametre = new Parametre();
			parametre.para1 = "para1";
			parametre.para2 = "para2";
			Parametre parametre2 = new Parametre();
			parametre2.para1 = "para1";
			parametre2.para2 = "para2";
			ksession.insert(parametre);
			
			WorkItemHandler handler = new WorkItemHandler() {
				public void executeWorkItem(WorkItem workItem,WorkItemManager manager) {
					System.out.println(">" + workItem.getParameters());
					System.out.println("Executing work item " + workItem);
					manager.completeWorkItem(workItem.getId(), null);
				}

				public void abortWorkItem(WorkItem workItem,
						WorkItemManager manager) {
					// Do nothing
				}
			};			
			
			
			Map<String, Object> parametersDispo = new HashMap<String, Object>();
			parametersDispo.put("parametre", parametre);
			
			
			
			ksession.getWorkItemManager().registerWorkItemHandler("groupe1",
handler);
			
			ksession.startProcess("com.sample.ruleflow1", parametersDispo);
			
			ksession.fireAllRules();
			logger.close();
		} catch (Throwable t) {
			t.printStackTrace();
		}
	}

	private static KnowledgeBase readKnowledgeBase() throws Exception {
		KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
		kbuilder.add(ResourceFactory.newClassPathResource("Sample4.drl",
RuleFlowTest.class), ResourceType.DRL);
		kbuilder.add(ResourceFactory.newClassPathResource("ruleFlow1.rf"),
ResourceType.DRF);
		
		KnowledgeBuilderErrors errors = kbuilder.getErrors();
		if (errors.size() > 0) {
			for (KnowledgeBuilderError error: errors) {
				System.err.println(error);
			}
			throw new IllegalArgumentException("Could not parse knowledge.");
		}
		KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
		kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
		return kbase;
	}
	
	
	public static class Parametre {
		
		private String para1;
		private String para2;	
		
		
		public String getPara1(){
			return this.para1;
		}
		public String getPara2(){
			return this.para2;
		}
		
		
	}









One of my rules :

rule "test 1"

	ruleflow-group "groupe1"
	when
		p : Parametre( para1 : para1)
		 eval (para1 ==  "para1") 
		 
	then 
		System.out.println( "groupe1 test 1" ); 
		
end
