When an object property has a range class set but the range class is not in a class group, VIVO now gives you a reasonable choice of classes that are in a classgroup. However, statements created will then not show up in the public-facing view, though they are successfully created and can be seen in the back end.
The property in question is c4o:hasGlobalCountSource and the range of the property is the class c4o:BibliographicInformationSource.
We can fix this by putting BibliographicInformationSource in a classgroup and making it a subclass of vivo:Database rather than of http://purl.obolibrary.org/obo/ERO_0001716 (also Database). I can do the former in initialTBoxAnnotations.n3 but I can't find where the class hierarchy is declared.
