Binding variable or condition ----------------------------- Key: DROOLS-897 URL: https://issues.jboss.org/browse/DROOLS-897 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.2.0.Final Environment: Windows 8 Reporter: Sante Stanisci Assignee: Mario Fusco Labels: dynamic, instanciation, variable Attachments: rule.drl, workaround.drl 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.
