> In this simple rule:
>  when
>         r: Request( amount > 500 )
>         String( this == r.id ) from requests
> For some reason MVEL is failing with the following exception:
> Testcase: hello(com.salaboy.mvelissue.MvelTest):	Caused an ERROR
> unable to invoke method: com.salaboy.mvelissue.Request.getId: target of method is null
> java.lang.RuntimeException: unable to invoke method: com.salaboy.mvelissue.Request.getId: target of method is null
> 	at org.mvel2.optimizers.impl.refl.nodes.GetterAccessor.getValue(GetterAccessor.java:66)
> When a new set of rules is being added to the kbase and an activation is generated.
> I've included a version of the failing rule working with a workaround, but both should work
