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