> in a drl file with a rule "reset" ad a function "formatDate",a bad behaviour is verified when is called the function in the "when" block..it call the function many times, but if the function called is stored in a external java file (not drl) everything works fine, and it call the function only 2 times (correct).
> Here the code of the drl file:
> rule "reset"
>         when
>                 $conversation:Conversation(resource.code == "sms", tickets.size > 0)
>                 not Discount(date == (formatDate($conversation.getStopDate())))
>         then 
>                 Discount discount = new Discount();
>                 discount.setDate(formatDate($conversation.getStopDate()));
>                 discount.setQuantity(495);
>                 insert(discount);               
>                 System.out.println("reset " + discount.getDate());
> end
>  
> declare Discount
>    date : String
>    quantity : int
> end
>  
> function String formatDate(java.util.Date date) {
>         java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("dd/MM/yy");
>         return formatter.format(date);
