Gryf, 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 workflow_rules you are referring to are describing 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); Kris Quoting gryf(a)hippogrif.dk: Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm
