Controllers not properly managed by the engine
This issue is related to the comments !128 (comment 1103406) and !128 (comment 1103404).
Requirement
From OSC1 standard perspective there is always the implicit default controller (not mentioned in the scenario for convenience, but must be considered in the implementation) and additionally you can have one (in OSC1.2 even multiple) user-defined controller. So you have one or multiple controllers for an entity.
Issue
At the moment the ControllerCreator will only create one controller for each entity ... but since there is only one controller it is not meaningful to activate it explicitly.
