Re: [rules-users] how to check difference between two .pkg files
Hi, It depends which version of Guvnor u r using. If its 5.x then, there are two ways to do this; 1. Use guvnor provided REST interface to get information related to packages. 2. Use JackRabbit API to directly access the repository as Guvnor 5.x uses JackRabbit as the assets repository.

[rules-users] Dynamic ValueRangeProvider
Optaplanners,
I'm looking to add some dynamic goodness to ValueRangeProvider. The only way I
see to specify a ValueRangeProvider is via annotation.
I'd like to be able to generate the id and Collection of candidate values
dynamically. Is it possible to generate the ValueRangeProvider data outside of
an annotation?
For example:
public class MyDataSource {
public Collection getValues(String id) {
…
return values;
}
}
Thanks,
Drew

Re: [rules-users] A Drools CEP Scenario - did I get it right?
1. A fact doesn't change until it *is* changed or the knowledge base
destined to operate it changes: so why should reasoning due to
the unchanged fact be repeated, with all consequential actions.
Continuing your line of thought would result in a hopeless muddle
if all consequences are re-executed each time fireAllRules is
called even where facts and rules haven't changed.
2. This works fine to adjust the pseudo-clock to the time of the next event,
about to be inserted in a "playback" run:
PseudoClockScheduler clock;
private void advance( Date eventDate ){
long currentTime = clock.getCurrentTime();
long eventTime = eventDate.getTime();
clock.advanceTime( eventTime - currentTime, TimeUnit.MILLISECONDS );
}

Re: [rules-users] A Drools CEP Scenario - did I get it right?
The question is more or less where to begin.
1. If there is a Fact in working memory (e.g. "Person") and I invoke
fireAllRules() twice, I would expect to have the following rule fire both times:
rule "alwaysFire"
when
$room : Room( )
then
System.out.println("there is a room");
end
I would also expect this rule to fire every time I invoke fireAllRules()
rule "alwaysFire2"
when
then
System.out.println("always!");
end
Both rules fire only once (the first time) even though the Working Memory is
the same. (The room still exists...). I expected the rule to fire each time
fireAllRules() is invoked and for the number of Rooms e.g. with 4 rooms -> 4x
output "there is a room".
2. It seems to be impossible to set the pseudo clock to a specific time. How
can I test CRON timer rules?!

Re: [rules-users] Guvnor REST api, compile package
I could not figure out why compile is not working. I solved it by changing Guvnor source - i removed 'is up to date' check. Now I have one more concern, is there a REST method to delete snapshot?
