Sorry, but I think you're not understanding what I'm saying. Let me rephrase. At COMPILE TIME we generate a syntetic Java method implementing the consequence's body. In your case it should be something like this:

{code}
public void doConsequence(Drools drools, X $entity, java.util.Map $t, java.math.BigDecimal $cambio) {
    $entity.setCodDiviCont($t.get("cod_divi_contab").toString());
    $entity.setCambioDiviCont($cambio);
    drools.update( $entity );
}
{code}

Of which type should be X in your case to make that method to work for all possible types of $entity?

> In this example I have more classes that extends EntityBase (my class). In my intention, i would assign to variable $entity one of this class that is inserted in Ksession fact.
> I insert fact of CtbMovrCoan class
> In when statement of the rule at row 16, variable $entity is correctely, 
> but in then statement variable $entity becomes JtbRLavt class (first declared in then cond) and this behavior throw a ClassCastException, obviously.
> Can Help me?
