Re: [rules-users] Drools Flow within Stateless Session in Drools 5.1

Hi, I have spoken with the Drools developers and they are aware of the problem and are going to fix it. In my previous post, I mentioned that if you comment out the line: wm.setRuleFlowEventSupport(this.ruleFlowEventSupport ); in the function newWorkingMemory() within the file StatelessKnowledgeSessionImpl.java, it will solve the problem (but potentially cause others.) The reason commenting out that line solves the problem is that the default constructor for a StatefulKnowledgeSession (which StatelessKnowledgeSession wraps) sets a Rule Flow event listener which is actually responsible for making Rule Flows work within Expert. It listens for when a Rule Flow group is empty, and sends the proper signals for advancing to the next Rule Flow group. The line in question above is meant to allow any custom Rule Flow group listeners you might have set on the StatelessSession to work on the temporary StatefulSession used internally, but unfortunately, it erases the one set in the StatefulKnowledgeSession constructor that Flow needs to work. As I said, I have reported this issue. If you comment out the line, the main functionality will work (as far as I am able to determine), however no custom Rule Flow events will work. The real fix will be to merge the two objects. Hope this helped, Jeff -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-Flow-within-St...
