Michael Anstis commented on DROOLS-3406:
----------------------------------------

All going good [~roger600]; but I have a question.

Do I have to _map_ Lienzo/Wires events (in response to drag/move/resize etc) in {{WiresShapeViewExt.addHandler(..)}} to Stunner {{ViewHandler}}?

I have some new Lienzo/Wires events being raised for moving the "splitter" that I _can_ handle in my new {{AbstractCanvasHandlerRegistrationControl}} implementation (to get access to a {{CommandManager}} etc) however looking at existing code it looks like I should have {{WiresShapeViewExt.addHandler(..)}} handle the Lienzo/Wires event and re-raise as a Stunner {{ViewHandler}} event... problem is that moving the "splitter" cannot re-use one of the existing {{ViewEventType}} and adding a new type seems more effort than it's worth (since it's an {{enum}}).

> The _splitter_ within a Decision Service is static.
> It needs to be movable (vertically) maintaining it's alignment with the Decision Service bounds. At this point we need to either decide to add _result_ decision(s) and _encapsulated_ decisions to the Decision Service by Command (depending on where the node is dropped) or update the Marshaller to determine the type of decision based on its vertical positioning and location of the _splitter_.
> h2. Acceptance test
> Decision state is updated according to _splitter_ movement. Example if area of result decision expanded so some decision belongs there now, this decision should have state _rusult decision_
