So, why is this property changing the behaviour of the rules?

Absence of facts (and events) is not a good foundation for rules, as you
have discovered.
Consider that the arrival of an event with some specific itemName is
another fact, and you want to monitor the aging of that secondary fact, or
cancel it as soon as yet another one arrives.

Hi there,
I'm working on a rule that will alert me when there is no events from the
sensors for a while.
So, first idea was to use time window and matches in condition side, to
match all types of sensors, and then to print that something is wrong.
rule "Alert if there is no activity"
when
no
nance, I'll give the
agenda groups a try...
Cheers,
Andreas

Betreff: Re: [rules-users] Truth maintenance
Have you considered using Droo
Have you considered using Drools built in phase control instead of your own?
Either agenda groups or a rule flow should do the trick and I neither of
these options affect logical inserts.

Hi,
I have a question concerning the truth maintenance mechanism in Drools:
Is it possible to exclude some preconditions from truth maintenance?
We want to implement a rule flow by using an attribute of a special
fact (ProcessPhaseController.phase).
We have some phases that we want to traverse.
