Mario Fusco commented on DROOLS-897:
------------------------------------

Do you mean that we should have different consequence implementations and select the right one at runtime? Honestly this will have an awful performance impact only to cover an extremely limited use case that in my humble opinion has been generated by a badly designed domain model. Sorry, but for sure this is not going to happen.

> 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?
