[jboss-jira] [JBoss JIRA] (DROOLS-159) Wrong execution order when explicitly setting SalienceConflictResolver

[Davide Sottara (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779275#comment-12779275 ] 

Davide Sottara commented on DROOLS-159:
---------------------------------------

Confirmed (and easily fixed), but you are still using Drools-4 and earlier methods and classes. 
The SalienceConflictResolver can be omitted since the engine manages salience natively.
They may be removed/refactored in 6+, so I would recommend to upgrade to the Drools 6 public APIs.
Thanks,
Davide

> When setting the conflict resolution strategy to Salience the execution order of the rules is incorrect: the rule with the lowest salience value is fired first.
> The Salience conflict resolution strategy is set by defining it in the RuleBaseConfiguration:
> {code}RuleBaseConfiguration rbc = new RuleBaseConfiguration();
> rbc.setConflictResolver(SalienceConflictResolver.getInstance());
> RuleBaseFactory.newRuleBase(rbc);{code}
> When the rule base is created without setting the conflict resolution strategy to Salience the execution order of the rules is correct.
