Clojurians Log v2

Thank you do much for your help! Could you clarify one question: "not so happy path in the model" 1. if im the model im the calculation of the cell there is an Exception .. what would happen? Crash? Exception moving down to the children? 2. Is there special type say "error" that if any of the inputs of a formula cell have error then output would be error as well. 3. I think of the usecase "data loading" where a "not available" temporary error type would make sense. Of course all of this can be extended by macros .. just wondering how it is now. Thanks!!!

Cells does not accommodate exceptions in any way. So if a rule or watch function fails, the app just crashes. ie, if we know one may fail, we need to code an exception trap and not let the failure escape. Background is that a single state change can kick off any number of rules, and their watch functions are dispatched immediately, so the horse is out of the barn, if you will.

Thanks! Very important to know!
