        that defaintely sounds like a bug - want to log it in a JIRA? 
        
        If it was not allowed in a drl, it would complain at compile time, and 
you would not be able to run the rules.

                Hi all,
                I'm using Jboss Rules 3.0.5 and Java 1.5.0_09.
                I'm using generics, but I see that I can't have the character < 
in a Fact in te drl. This is not a problem, I derived my generic class, and the 
new derived one is not a Generic class... 
                
                (public class MyClassCiccio extends Ciccio<MyClass>{})
                
                Now, when I execute the application without log it works. But 
when I instantiate a WorkingMemoryLogger I have a ClassCastException:
                
                Exception in thread "main" java.lang.ClassCastException:

                Is this a bug? Or the generics are not supported and this is 
the reason < is not allowed in the rule file?
                Attached there is the example application.... I simply zipped 
the Eclipse Project Directory... I hope this is the right thing to do, if not 
please redirect me to the right place... 
                Thanks in advance....
