David Tildesley commented on ISIS-561:
--------------------------------------

view objects belong in the UI layer. domain layer should be independent of UI 
layer. There is a requirement to have non-persisted domain objects. Persistance 
is just an injected behaviour to the domain object (save me). Many times a 
domain graph is created from a system to system interaction (i.e. calling  an 
external service to get information or put information).

> Now we have support for view models, we could simplify matters elsewhere by 
> removing support for transient objects.
