[rules-dev] use of declared facts

There's now possibility to declare facts in the drl, like: declare Person name: String age: int end My question is how do I instantiate this fact object during runtime? Do I still need to have class Person compiled and existing somewhere in classpath, or there's a helper class which I can use "fake the fact", something like: FakeFact person = FakeFact("Person"); person.setField("name", "Oleg"); person.setField("age", "42"); session.insert(person); Or there's another nicer way? Thank you, -Oleg Zenzin
