regarding "takeable": currently takable means that a user participates as 'candidate'. but it's an implementation detail of the findTakable() and take() methods. IMO you should come up with something else that's more close to the participation model and is reflected properly in the TaskService interface. I.e: | findTaskByParticipation(Identity, Participation.CANDIDATE) | Not only would it shed some light on what's actually going on, but it also open the door for other participation types.
