> I'm getting the following Error "Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction at 631b86c7" with one off my rules in my project. 
> The problem is linked with the use of two after statements in one rule. 
> If I delete one of them everything works like a charm. 
> The rule looks like this: 
> // Regeln 
> rule "Vergessene Herdplatte" 
>     when 
>         // Platte wurde eingeschaltet und es steht kein Topf auf ihr 
>         $platte: HerdplatteEingeschaltet( plateOccupied == false ) from entry-point events 
>         // und in den nächsten 20 sek wird die gleiche Platte nicht ausgeschaltet 
>         not( HerdplatteAusgeschaltet( this.nummer == $platte.nummer, this after[0s,20s] $platte ) from entry-point events ) 
>         // oder es wird in den nächsten 20 sek kein Topf auf die Platte gestellt 
>         not( TopfAufHerdplatte( this.nummer == $platte.nummer, this after[0s,20s] $platte ) from entry-point events ) 
>     then 
>         System.out.println("Vergessene Herdplatte erkannt!"); 
>     
> end 
> If I comment one of the not-clause out, it works. 
> I created an unit-test which reproduces the exception.
