             Summary: BigDecimal in from accumulate with MVEL with executable-model
                 Key: DROOLS-4375
                 URL: https://issues.jboss.org/browse/DROOLS-4375
             Project: Drools
          Issue Type: Bug
          Components: executable model
    Affects Versions: 7.24.0.Final
            Reporter: Toshiya Kobayashi
            Assignee: Luca Molteni


When "from accumulate" uses BigDecimal with Mvel syntax,

for example)
{noformat}
import org.drools.modelcompiler.domain.Person;
import java.math.BigDecimal;
global java.util.List list;
dialect "mvel"
rule R when
  $b : BigDecimal() from accumulate (
            Person( $money : money ),
                init( BigDecimal sum = 0; ),
                action( sum += $money; ),
                reverse( sum -= $money; ),
                result( sum )
         )
then
  list.add($b);
end
{noformat}

It works with non executable-model but fails with executable-model.
