In Drools 3 this is much clearer.
You would do a statement like: IF GenericComparable(primary == true)
Much neater, and you don't even have to declar the parameter of that type
(it is implicit in that case), and yes, it will understand "is" is actually
a getter (lots of people forget).
I think classifelds at the moment only work, with Strings, but I can't be
sure having not used them myself.
