> It appears that after don'ing the trait the map-based fact it is proxying disappears (or gets retracted).
> There does not seem to be any issue using the trait properties to access the model properties.
> We are trying to use the model, mostly for constraints and updates, then within the rules apply and use traits to give us a stronger-typed fact and easier rule constraining.
