Sante Stanisci commented on DROOLS-897:
---------------------------------------

ok, I'll take the hint. 
My intention is to use only one rule for most classes that share common fields. 

Drools should properly instantiate the variable $entity to the correct class.
I don't understand why in the when statement instantiation is correct and in then statement, change class.
This is a issue!? In my opinion, yes.

> 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?
