-------------------------------------

             Summary: ClassCastException using accumulate max in executable model
                 Key: DROOLS-4535
                 URL: https://issues.jboss.org/browse/DROOLS-4535
             Project: Drools
          Issue Type: Bug
          Components: core engine, executable model
    Affects Versions: 7.26.0.Final
            Reporter: Martin Weiler
            Assignee: Mario Fusco


A rule containing the following accumulate constraint:

{noformat}
  $max1 : Number() from accumulate(
    StockTick($time : getTimeFieldAsDate());
    max($time.getTime()))
{noformat}

is successfully compiled using the executable model, but fails at runtime:

{noformat}
