[jboss-jira] [JBoss JIRA] (DROOLS-654) Dynamic update with KieContainer.updateToVersion() not working when ksession was created with config

[Tihomir Meščić (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13023375#comment-13023375 ] 

Tihomir Meščić commented on DROOLS-654:
---------------------------------------

Thanks for clearing this up, but, is there another way to:
 1. use Drools in Stream mode (I use window:time, so I need this), and
 2. have the ability to update rules in runtime ?

> I'm creating my {{KieSession}} by setting {{STREAM}} as the event processing mode in the configuration:
> {{KieBaseConfiguration config = KieServices.Factory.get()}}
> 				{{.newKieBaseConfiguration();}}
> 	{{config.setOption(EventProcessingOption.STREAM);}}
>         
>         {{KieContainer kc = ks.newKieContainer( ... releaseId ... );}}        
>         {{KieSession ksession = kc.newKieBase(config).newKieSession();}}
> After that, everything works fine. But when I try to dynamically update to a new version (containing new rules):
> {{kc.updateToVersion( ... newReleaseId... );}}
> It seems like all of the facts are removed from the session, and my rules are no longer triggered. 
> When I do not use the configuration object when creating the session and just use:
> {{KieSession ksession = kc.newKieSession();}}
> then, everything works as expected. However, this is not an option because I need a way to specify the processing mode as {{STREAM}} (and this is the only way I know of).
