[rules-users] process order example not working fully

[Kris Verlaenen]

Aziz,

The order example can be executed using what we call "advanced execution
mode".  In that case, you are not automatically going from one node to
the other in your process all the time, but we allow other rules to
intervene and possibly override the default behaviour.  The logging
rules and assignment rules in the example show how to add additional
behaviour in this advanced execution mode.

However, because advanced execution mode is still experimental (as very
powerful and the user needs to know much more internal details to use
them effectively), so we did not enable it by default.  If you want to
enable advanced execution mode, add this line before adding the
knowledge packages to the knowledge base:

((InternalRuleBase) ((KnowledgeBaseImpl) kbase).getRuleBase())
  .getConfiguration().setAdvancedProcessRuleIntegration(true);
