Hi Aerv, soon I will also have to launch Drools within an OSGI environment, but I am not there yet. But within another context (jBPM) I had some troubles looking similar you are having. It had something to do with the classloading. jBPM did not provide any OSGI-support, whereas Droos does,

It seems that Drools is confused by the usage of the class name "Decision" (which is used in the core: java/org/drools/jpdl/core/node/Decision.java I can reproduce a similar effect, simply by renaming a class in a working example to "Decision". -W On Thu, Apr 15, 2010 at 12:49 PM, Ade Timi wrot

Re: [rules-users] Fusion and open-ended intervals?

Barry, This is usually solved using a pattern called "event abstraction". You model your "EventXStarted" and "EventXEnded" as atomic events (i.e., no duration) and write rules that depend on the start/end of the event against these atomic events. Then, you use a correlating rule to abstrac

Re: [rules-users] Fusion and open-ended intervals?

If I understand you correctly Edson, you have provided a better description to solution 1) in my post above. This works to a degree but leaves a bit to be desired. For example when correlating instant events as "during" the interval events (ie, startX, endX, eventX) those correlations cannot simp

Re: [rules-users] Fusion and open-ended intervals?

Barry, Yes, your understanding matches mine. The decision to make timestamp and duration constant is due to the many side-effects that making them mutable bring, as you guessed. I really want to do the next step and allow mutable temporal properties, but that requires much more research
