Mario Fusco commented on DROOLS-1168:
-------------------------------------

Passing a random long there is clearly wrong. That long is a bitmask calculated on the basis of the modified attributes of the fact you're updating, so creating a fake bitmask is not the solution.

Said that I don't understand why you need that DroolsUtil.completeEntity() method instead of invoking the proper setters directly on $entity, in case your modifying more than a field the workaround that I suggested should still work as in:

{code}
String[] fields = new String[] {"codDiviCont", "cambioDiviCont"};
DroolsUtil.completeEntity($entity, fields, $t.get("cod_divi_contab").toString(), cambio);
$entity.setCodDiviCont($entity.getCodDiviCont());
$entity.setCambioDiviCont($entity.getCambioDiviCont());
update($entity);
{code}

If this doesn't work for you my only other suggestion is giving up using property reactivity for this use case.

> in the then statement instead of modify use a custom function to change the field. This change does not notify the property even if the class is annotated with @PropertyReactive
> How can I manually notify the change?
> Use a stateless session
