I suspect that's actually the instanceId of a domain object that's neither a view model nor a persistent entity, ie is a "transient" entity (not yet persisted to the DB).
The RO viewer doesn't support such things (in fact, nor does the Wicket viewer anymore; they are a legacy of an earlier time). The fix, I expect, will be to make sure the entity is a properly annotated view model.
