Re: [rules-dev] SumIntegerAccumulateFunction not possible?
ok, that looks like a bug. please open a jira for it. It may well be
that we do only return Longs and Doubles, to save on duplicate apis, but
there should still be adequate coercion

Here's the piece of code:
public void accumulate(Object context,
Object value) {
SumIntegerAccumulateFunction.SumData data =
(SumIntegerAccumulateFunction.SumData) context;
data.total += ((Integer) value).intValue(); // breaks
}
Here's the drl:
when
$totalDistance : Integer() from accumulate(
Hop($distance : distance),
sumInteger($distance)
);
Here's the Hop object:
public int getDistance() {
...
}
Look ma, no longs :) Still a ClassCastException on them though.
I must be missing something really obvious?
