Are you running your code from within Eclipse (not in a separate JVM)?
If so, you shouldn't call the DomainmodelStandaloneSetup. Otherwise, use
a debugger to make sure the line
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "dmodel",
resourceFactory);
in DomainmdodelStandaloneSetupGenerated is called. This is where the
resource factory should be registered.

hello robin,
can you post your complete code loading the model. seems you are not callling standalonesetup.
this code works nicely for me
import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
import org.eclipse.xtext.example.DomainmodelStandaloneSetup;
import org.eclipse.xtext.example.domainmodel.DomainModel;
public class Test {
public static void main(String[] args) {
new DomainmodelStandaloneSetup().createInjectorAndDoEMFRegistration();
ResourceSet rs = new ResourceSetImpl();
Resource resource = rs.getResource(URI.createURI("./src/test.dmodel"), true);
DomainModel model = (DomainModel) resource.getContents().get(0);
System.out.println(model.getElements().size());
}
}

Hi,
the problem is simple but hard to find  you file extension is "dmodel " (ending with a blank) but your files have od course the extension "dmodel". so changing your workflow to
var grammarURI = "classpath:/org/eclipse/xtext/example/Domainmodel.xtext"
var file.extensions = "dmodel"
var projectName = "org.eclipse.xtext.example.domainmodel"
var runtimeProject = "../${projectName}"
might solve the problems  Note: you may have to merge plugin.xml and plugin.xml_gen
Feel free to file an enhancement request for a validation rule that complains on whitespace in the file extension.
