> When using 'contains' operator on array or collection of strings its working fine. But when we use it for an array of primitive type double it gives a classcastexception . Is auto boxing not supported? May be this is fine as it mentioned in the documentation that it works only on Objects. I tried using the array of Double objects, here it doesn't throw an excpetion but the rule wasn't firing. The behaviour was same even if I use a collection of Double objects. 
>  ex: 
> using Array
>      rule "OrderArray"
> 	 when
> 		 Order(valueArray contains 0)
> 	 then
>              System.out.println("OrderArray");
> end.
> using Collection
>  rule "OrderList"
> 	 when
> 		 Order(valueList contains 0)
> 	 then
>              System.out.println("OrderList");
> end.
