[rules-users] Why does it seem like salience is being ignored?

[Edson Tirelli]

   Sorry, just saw your message. fireUntilHalt() will work in your use
case, as Mark mentioned. With fireUntilHalt(), as soon as a rule is
activated, it will fire if the agenda is idle. Because the topology of the
discrimination network is affected by the order of the rules in the file,
you end up having this different firing order depending on the order of the
rules in the file.

   The only way to work around this with the current version of Drools is
to call fireAllRules() after each insertion of an object into the working
memory and the current implementation of the Drools-Camel component does
not support that. If you want to do it yourself, it is quite easy:

1. Add support to a new parameter to tell the component to fireAllRules()
after inserting the object into the working memory:

https://github.com/droolsjbpm/droolsjbpm-integration/blob/master/drools-camel/src/main/java/org/drools/camel/component/DroolsEndpoint.java

2. Add the call to fireAllRules() after inserting the object in here:

https://github.com/droolsjbpm/droolsjbpm-integration/blob/master/drools-camel/src/main/java/org/drools/camel/component/DroolsInsertProducer.java


   Meanwhile, for the next version, we will need to add a staging area to
the agenda where the activations of a given propagation are added to the
agenda only when the whole propagation completes. This will fix the issue
for the general case.
