I haven't decided how to handle the shared-object problem, but I'm leaning toward the Parameter + ObjectToken (or Parameter + accessor object) approach. However, I can't figure out how to update the value of a parameter from within a refinement. In the attached example, I'd like to set the value of the parameter "a" to the current time (mod 10) on some transitions, and leave it alone on others. However, I receive an IllegalActionException when the model tries to resolve types (in preinitializeAndResolveTypes), complaining that the type-checker "Cannot find port or variable with the name: a". (The same error arises if I try to set the value of "a" using an expression actor in a refinement.) Does this mean that parameters are immutable (at least in modal models)?
