[jboss-jira] [JBoss JIRA] (JBRULES-3558) Odd rules execution for expired events

[Karol Sobczak (JIRA)]

     [ https://issues.jboss.org/browse/JBRULES-3558?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Karol Sobczak updated JBRULES-3558:
-----------------------------------

        Description: 
I have declared two types:

declare Motion
  @role( event )
  @expires( 5s )
  @timestamp( eventTime )
  eventTime : long
end

declare Recording
end

and following rules:

rule "StartRecording"
  when
    Motion()
    not Recording()
  then
    insert(new Recording())
end

the problem is that when I put a lot of "Motions", sleep (so "Motions" become expired) and then do fireAllRules(), I got "StartRecording" executed multiple times (and not only once), event though "Recording" is inserted every time. 

Another issue would be when instead of "StartRecording" rule I would have "StopRecording" rule:

rule "StopRecording"
  when
    $m : Motion()
    $r : Recording()
  then
    System.err.println("Recording: " + $r);
    retract($r);
end 

then when there is a "Recording" fact inserted and multiple expired "Motions", the rule would be executed multiple times (when "Motions" expire) and $r would be null after the first "StopRecording" rule execution.
