Fact checking before evaluating rules

[Clayton7510]

That's an interesting question. While there is no specific mechanism for checking that required facts exist, there are a few tools at your disposal with RuleBook. I also think that it might be a nice feature addition to add targeted functionality to specify required facts.

In the meantime, you could certainly have a precondition rule that does nothing but check facts and either return no result or throw an exception (based on your logic) if certain facts are not available. Another option could be to create a facade on top of your RuleBook that requires certain facts to be added prior to executing the RuleBook.

I like the precondition rule idea, thanks. How do I continue rule processing if the preconditions are satisfied? I thought rule processing stopped when the first matching rule fires.
