RHS is not DRL syntax but Java or MVEL depending on your dialect.
If "id" is not public you should use it's getter. The same goes for
"quantity".
when
$item : Item(param1 != 0, param2 == 0, !(this instanceof SpecialItem))
$gsc : SomeBusinessLogic
then
$gsc.doSomething($item.getId() );
for (int i = 0; i < $item.getQuantity(); i++) {
$gsc.doSomethingElse($item.getId() );
}
update($gsc);
end
