> We are using Drools engine on our client written in C#. We are using IKVM
> to convert the drools jar and our java beans into dll's using IKVM. We have
> a rule similar to this:-
>
> rule "aggregate rule"
>     when
>         $b : Bill(billAmount > 100)
>         $n : Number(doubleValue > 100) from accumulate ( $l : LineItem()
> from $b.findItems("color", "blue"), sum($l.getSellingValue()))
>     then
>         VoucherSeries fact0 = new VoucherSeries();
>         fact0.setSeriesCode( "aggregate voucher" );
>         insert(fact0 );
>         voucherlist.add(fact0);
>         System.out.println("sum" + $n);
> end
>

> This rule works fine when it is run with java based drools API's, but while
> running it with IKVM converted drools, it throws the following error:-
>
> Unable to cast object of type 'AccumulateMemory' to type 'FromMemory'.
>
> Any ideas on what might be going wrong ?
