"Re: Waiting for events to occur in a flow?" To view the discussion, visit: https://community.jboss.org/message/762449#762449 -------------------------------------------------------------- First of all, how do you run the process - jbpm-console, unit test, custom application? In general, to activate a rule you need to insert/update/retract facts to/from the session. Once rule is activated you can fire it using firellRules. > Jim Beam wrote: > a) in #1, why doesn't the first rule fire? > > I believe nothing was added to session so no activation took place so nothing to fire > Jim Beam wrote: > b) and Why/How does the process exit without a "Done" message?

This is the answer to part 2, as soon as you fire rules it will trigger business rule task to continue > Jim Beam wrote: > d) as I read it in the documentation, the rule task should keep the > process from advancing until all of the rules are no longer active.

As far as I know business rule task does not wait for a condition to be met, it simply executes rules that are active at the time when rule task was executed. > Jim Beam wrote: > e) what is the right way to do this sort of thing? > f) Can someone clue me into what I am doing wrong?

Conditional event will wait until defined condition is met and move on only when that condition is met. Take a look at the example https://github.com/droolsjbpm/jbpm/blob/master/jbpm-bpmn2/src/test/resources/BPMN2-IntermediateCatchEventCondition.bpmn2 here.
