Question: Returning the custom added param in successes about json-rules-engine HOT 1 CLOSED

Hi @JagadishaBS factResults are generated by the engine when it runs. It is only accessible via the on('success') event you already referenced.

I'll note that from the example you gave above, it looks to me like you're trying to pre-define factResults in the rule conditions, and have the values carry through as the engine runs (Let me know if I'm mis-interpreting). Rule conditions aren't meant as a means to store state - that's why they have a fairly rigid data structure. If you need to associate additional data with each rule, look to the events, where you can provide params. Finally, when needing to associate more complex data structures with a rule, don't be afraid to structure the data outside the engine - sometimes simply hashing the data by the event type in a variable, and then pulling out the data you need in the on('success') handler is a good way to go.

If you are still having problems or I'm misunderstanding your problem, it may helps to post a script/repo I can run that demonstrates your problem.
