Dear Jess users, I am still learning the ropes, and cannot find an answer to the following question either online or in the 'Jess in action' book. Is there a way to match facts in a LHS based on the presence of a slot?
For example, I have two templates: (deftemplate A (slot score)) (deftemplate B (slot score)) I would like my rule to be triggered if any fact (either from template A, B, or others) have a 'score' slot with a specific value. For now I can do it by manually adding references to A and B in the LHS, but this will not scale well. I'm looking for a solution that can just work on any fact, regardless of the template they are defined from. Best, Aurelien
