[rules-users] Ordering rules execution: ruleflow-group or salience?

Hi all, I have some complex rule execution scenario which consists of several steps where different groups of rules must be executed. These steps are: 'Init Data', 'Validate Integrity', 'Stop Execution if any integrity errors found' and 'Validate Business Logic'. Originally I implemented it by assigning specific salience to specify an order of rules, like 'Init Data' rules has biggest salience, and 'Validate Business Logic' rules has the smallest. I am wondering, is designing separate rule flow (very simple) is a valid approach and wouldyoy recomend it? It should look like: 'Start' -> 'Init Data' -> 'Validate Integrity' -> 'Stop Execution if any integrity errors found' -> 'Validate Business Logic' -> 'End'. Also, I tried to do it by specifing 'ruleflow-group' for each rule and creating rule-flow, but got an error 'Unknown process ID' while executing. The code was very simple - 1st I added rule-flow file as resource to KnowledgeBuilders DRF resource with: Resource flowFileRes = ResourceFactory.newFileResource( flowFile ); knowledgeBuilder.add( flowFileRes, ResourceType.DRF ); knowledgeBuilder.hasErrors() is false at this point, so I assume that process was added sucessfully. Then I am executed: session.startProcess( MAIN_FLOW_ID ); session.fireAllRules(); MAIN_FLOW_ID constist of package defined in rule-flow file and rule-flow-ID from the same file (<package>.<flow-ID>). But fireAllRules() claims that no such process can be found (Unknown process ID). Documentation is very weak and it is the only information I found about executing processes, so perhaps I miss something, but mailing list seems like the only place to find more info. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Ordering-rules-execut...
