There are some questions on your reply: laune wrote All activations from group A have been fired.

When you say the agenda group becomes active again, do you mean the agenda group A become active? laune wrote Focus may be given (by an API method call) to another agenda group B while there still are some activations from group A pending. Eventually, A will receive the focus again, and rule firings from A continue as usual. How does the agenda group A give its focus to B? Is the API setFocus?

Re: [rules-users] How to use a temp variable accorss multiple rules?
Where should I define the Output class, in Java code or drl file? How about if the Output is only a int or double value? Must I wrap the value into a Java class? -- View this message in context: http://drools.46999.n3.nabble.com/How-to-use-a-temp-variable-accorss-multiple-rules-tp3509713p3509799.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] What is Entry point and Rule fact?
For my understanding, Rule Fact is the object inserted in the session, right? How about the entry point?

Re: [rules-users] How to run an agenda group multiple times?
According to Drools export document, *Each time setFocus() is called it pushes that Agenda Group onto a stack. When the focus group is empty it is popped from the stack and the focus group that is now on top evaluates. An Agenda Group can appear in multiple locations on the stack. * If I run setFocus() on an agenda group two times, the agenda group should be in multiple locations on the stack, why the rules in this agenda group are fired only once?

[rules-users] How can I get rule's agenda group name?
I add an AgendaEventListener on a statefulesession. In beforeActivationFired method, I can get a Rule object by BeforeActivationFiredEvent.getActivation().getRule(). If the rule is configured in an agenda group, how can I get the agenda group name from the Rule object?
