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.
