Re: [rules-users] [FUSION] Detect the absence of an event when you don't know that the event is missing.

Yeah, normally I would solve it that way. But you're using a time (1d) which I unfortunately don't know off in my scenario. I'm afraid that there will be no other solution than that I have to use a time... Thanks anyway :) Sounds that you can use the Not Conditional Element for that right? something like $a: EventA() not EventB(this after[1d] $a) On Fri, Oct 22, 2010 at 5:49 PM, Tina Vießmann < tviessmann(a)stud.hs-bremen.de&gt; wrote: > Hi, > > I'm working on a use case where I want to know if 20 events with a > specific value are contained in at maximum the last 150 events.
