Fundamentally domain objects are either persistent entities (@PersistenceCapable) or they are view models (either @ViewModel, @DomainObject(nature=VIEW_MODEL) or, now, @XmlRootElement).... and they can't, or aren't intended to, be both. When the framework recreates domain objects from the OID there is an if/else; just checking the code [2] it will treat the domain object as a view model even if annotated with @PersistenceCapable. It's state will then be recreated from the encoded information within the OID itself. I realise that I don't fully understand the use case you want to be able to support here. In general though I think that treating JAXB view models as entities is a bad idea, because retaining backward compatibility to possible clients of the on-the-wire format would constrain - probably too tightly - the corresponding implementation details when used directly as a persistent entity. > Well almost, one other thing I realise now is that some of the constraints > that you can specificy in your XML Schema are not translated to Java, so > you still have to specify the original schema file when marshalling from > Java to XML to impose those constraints (e.g min or max length of xs:string > types). > > It would certainly be easy enough to extend Isis so that it natively recognises those annotations (just as it recognizes @javax.jdo.annotations.Column#allowNulls to indicate optionality. I've updated ISIS-1289, please feel free to add further ideas.
