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

             Summary: Executable model compilation fails with ClassCastException when using accumulate and additional constraint
                 Key: DROOLS-4659
                 URL: https://issues.jboss.org/browse/DROOLS-4659
             Project: Drools
          Issue Type: Bug
          Components: core engine, executable model
    Affects Versions: 7.28.0.Final
            Reporter: Martin Weiler
            Assignee: Mario Fusco


A rule containing the following constraint:

{noformat}
  when
  $customer : Customer( code == "RHT" )
  $max1 : Number() from accumulate(
    StockTick( company == $customer.code
    , $time : dueDate);
    max($time.getTime().getTime()))
{noformat}

fails with a ClassCastException when building with the executable model:
