[rules-users] Is this syntax correct?

[Shai Bentin]

I need to fire a rule if I have more then one fact that has an endDate property from the last 24 months... is the follwoing correct?  
   
  

rule "testing123"    

when    

olList: ArrayList(size > 1) from collect(CreditEventLocal(creditEventTypeVlId == "SOMETHING", $endDate: endDate -> ($endDate.after(DateUtils.addMonthsFromToday(-24)))))  

then    

System.out.println("eurika");  

end  

   

Anyhow, if it is then I get a NullPointerException which doesn't tell me what the problem is. It happens in building time of course:  

I'm using drools4.0.0MR2  

Exception in thread "main" java.lang.NullPointerException
