There will be an index on that slot, and so if there are many obj's, then won't all be checked against the content of the multislot. But multislots aren't the most efficient thing in Jess. I wish I could think of a better way overall to handle them, but so far I haven't. > > Jason: The reason I am not using logical is that the dependencies > exist in my domain-level data, not > in how the facts are constructed via rules.
