XtextResource#doSave() verifies that the resource only contains a single top-level object (i.e. getContents().size() == 1).  At the same time the JvmModelXbaseLazyLinker will install additional top-level objects for any inferred objects.

Should the check in XtextResource#doSave() be weakened or is a language such as Domainmodel required to subclass LazyLinkingResource if it needs to serialize a model using the standard EMF resource API?

Domainmodel test case to reproduce the problem:

public class Main {

	public static void main(String[] args) throws IOException {
		Injector injector = new DomainmodelStandaloneSetup().createInjectorAndDoEMFRegistration();
		XtextResourceSet resourceSet = injector.getInstance(XtextResourceSet.class);
		Resource resource = resourceSet.createResource(URI.createURI("foo.dmodel"));
		resource.load(new StringInputStream("entity Foo {}"), null);
		resource.save(null);
	}
}
