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<http://item.id/>);
for (int i = 0; i < $item.quantity; i++) {
$gsc.doSomethingElse($item.id<http://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 $ :)

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