My request object has a result object that has a method called setDiscount that needs to be called. The setDiscount cannot be in the request object because there are multiple kinds of Result Objects, thus the casting to its type. This rule works fine, I was just wondering if there are any easier ways to do it.

Is that the solution? That seems odd to me because IsBadDebtor is an
inferred object and should have the class Debtor. When you have to declare
a class for every type of inferred object you are using that would be
strange. These classes would extend the class where they are inferred from
and would be totally empty: no own attributes, nor methods. They would only
be declared to solve this compilation issue.

Re: [rules-users] Inserting facts using declared types from XML
XStream is a simple library to serialize objects to XML and back again.
Sometimes it can get tedious to call all those XStream aliases/register
converter methods or you might simply like the new trend on configuring
POJOs: Java annotations.
While using annotations if you ever got this exception the there might be a
change that you forgot to call process annotation
XStream stream = new XStream(new DomDriver());
stream.processAnnotations(YourClassName.class);
Calling stream.processAnnotations(YourClassName.class); will clear down
this exception.

into an issue where the XStream unmarshaller is unable to convert my XML to
a BatchExecutionCommand because it cannot find the class for a type

Is there any configuration required to make sure the XStream marshaller
knows about the dynamically generated classes from the .drl?
I'd appreciated any clues. I cannot add POJO classes for my types due to
