Re: [rules-users] Rule Flow and Stateless Session

Hi John, this is a known issue 
https://issues.jboss.org/browse/JBRULES-2718. The fix is in 5.2.0.CR1 
which you can get from http://www.jboss.org/drools/downloads.html.


Thanks.

My rule flow is simple: Start-RuleGroup1-RuleGroup2-End
I use the 2 rules from example, putting the "Hello World" in 
RuleGroup1 and "Goodbye" in RuleGroup2.

Here's my code to run it:
// load up the knowledge base
KnowledgeBase kbase = /readKnowledgeBase/();
StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession();
KnowledgeRuntimeLogger logger = 
KnowledgeRuntimeLoggerFactory./newFileLogger/(ksession, "test");

// start a new process instance
Message message = *new* Message();
message.setMessage("Hello World");
message.setStatus(Message./HELLO/);
ArrayList cmds = *new* ArrayList();
ArrayList dataList = *new* ArrayList();
dataList.add(message);
cmds.add(CommandFactory./newInsertElements/(dataList));
cmds.add(CommandFactory./newStartProcess/("com.sample.ruleflow"));
ksession.execute(CommandFactory./newBatchExecution/(cmds));
logger.close();
When I run the rules, all I get is "Hello World" (no "Goodbye cruel 
world").  It does work with a Stateful Session using insert, 
startProcess, and fireAllRules, but this is a test using the rule 
flows with CommandFactory functionality, something we need for an 
application we are developing.

[rules-users] Rule Flow and Stateless Session
