Subject: Re: [rules-users] For loop inside a modify block problem

Why no braces after SomeBusinessLogic?

Also your logic is wrong there. Item is not a collection so your for loop is repeating the same action over and over again for the same data.

[Swindells, Thomas] It does look like that but it depends what the action is. Perhaps it is integrating with a rubbish stock system which can only remove one item at a time, to remove n identical items you have to call it n times.

Hi, Davide,

Here is how my rule looks like :

when

$item : Item(param1 != 0, param2 == 0, !(this instanceof SpecialItem))

$gsc : SomeBusinessLogic

then

$gsc.doSomething($item.id);

for (int i = 0; i < $item.quantity; i++) {
$gsc.doSomethingElse($item.id);
}
update($gsc);

end

The above snippet throws an error @ i < $item.quantity, and says 'no such identifier $item'...

I can't figure out what might be causing this.

Thanks

Did you remember to bind $item to some expression in the LHS ? Maybe you just
called that "item" without the $ :)
Davide

(the original "modify" syntax is still wrong anyway)
