Is there a way to determine via code which Role(s) belong to an activity instance?  I have a parallel activity with four roles.  All four roles need to approve for the activity to be approved but only one needs to reject.  In my client code, I want to know which role is assigned to the activity instance I'm referencing so I can write to appropriate fields in the database.  Right now, the assumption is that a user will not be in multiple approver roles, but this may not always be the case.  It would also be easier than checking all the roles to determine if the user is in a particular role.  Does all this make sense?  Does anyone know if it's possible to do what I'm asking?
