Re: [rules-users] Temporal operator before[1ms, oo] exhibtis strange behaviour
Wolfgang,
It seems you are doing a great QA job all around Drools. Thanks.
Can you open JIRA's for this and the other quirks you've been
finding? We will work on them as we approach the release date.
Thanks a lot,
Edson
2010/11/4 Wolfgang Laun <wolfgang.laun(a)gmail.com>:
The .drl:
declare Leave
@role( event )
@timestamp( timestamp )
end
rule "XXX Leave not !="
when
$leave: Leave()
not Leave( this != $leave )
then
System.out.println( "XXX only one Leave - not !=" );
end
rule "YYY Leave not after"
when
$leave: Leave()
not Leave( this before $leave )
then
System.out.println( "YYY only one Leave - not before" );
end
A) The pseudo-clock is advanced according to the timestamp; then
exactly one event Leave is inserted; then fireAllRules() is called.
1) Running in CLOUD mode, both rules fire.
2) But running in STREAM mode, ONLY rule XXX fires.
B) Like A, but the session clock is advanced by (at least) 1ms
prior to calling fireAllRules().
3) Either mode, both rules fire.
I think that A2) is incorrect; why should passing another msec change the
logic?
JIRA?
Wolfgang
