Hi,
Can you post the relevant part of your code here (call to RH_GET_ACTORS)?
I am not 100% but I have a feeling that I have used RH_GET_ACTORS to get agents from responsibility rule, and there was nothing special or difficulties about it.
Or what do you actually mean that you don't have the container values? Surely you should have some parameters for your rules, if you want to have correct results, or am I missing a point here?
Regards,
Karri
