[rules-users] problem in sliding window

[Sandhya Sree]

hi,

i have a rule file as follows:

declare Event
    @role( event )
end

declare window Ticks
    Event()
        over window:time(1m )
end

rule "More than  5 file added events"
when
    $p: RuleContext()
    Number(intValue > 4) from
    accumulate( $e :Event (name == "new file added") from window Ticks,
count($e) )
then
      Event event = new Event("too many files added last
minute",$p.getOldContext().getParent(),new
            Date());
       event.display();
end


this rule gets fired only if i add more than 4 files all at once..
say if i add first 2 files within the first 10 seconds, next two files
after the 20th second and next two files after 40th second, this rule is
not getting fired.. ( there are 6 file added events in the window over past
1 min and the rule should have got fired ). what is the problem with the
current rules and how can i modify it to meet my requirement?


Thanks.
