* any intermediate changes in the Edit window will be applied automatically to the List window
* (they're both binding to the same instance). Whenever we cancel (i.e. use IEditableObject.CancelEdit())
* the changes will be reverted and the List window will be back to its original state.
*
* 2* If we use "Content = new VesselViewModel(vessel)", there's no need to implement
* IEditableObject on VesselViewModel, because we're passing a new instance to the
* Edit window every time and it will be discarded both on Save and Cancel.
*
* 3 * another approach is to simply send the id to the interaction request and have it deal with it.
