Re: [rules-users] For loop inside a modify block problem
Using 5.3.0 Final.
The reported compilation problem ("no such identifier: $item") occurs
with dialect MVEL, which appears to be broken w.r.t. RHS code containing
a "for" statement. Note: the error is not flagged for the preceding occurrrence
of $item, in $item.id.
Different kind of errorscan occur, depending on how the "for"
statement is written,
for example:
int h = 10; for( int i = 0; i < h; i++) { ... } ## Error: no such
identifier: h
Avoid dialect MVEL - using Java and getters works fine.

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
