Assume we have the following grammar:

Model:
	entities+=Entity*;
	
Entity:
	'entity' name=ID ('extends' extends=[Entity])? '{'
		arributes+=Attribute*
'}'
;

Attribute:
	'attr' name=ID
;

And these model files

file1.mydsl

entity file1 {
	attr a1
	attr a2
}

file2.mydsl

entity file2 extends file1 {
	
}

the editor for file2 is open and i do a file rename (F2) on file2.mydsl

now if i (e.g in scoping) am asking the resourceserviceprovider for the resource description of the resource i am working on, then i get null as result.

(we use the index to create some implicit imports)

to reproduce that simply use

public class MyDslImportedNamespaceAwareLocalScopeProvider extends ImportedNamespaceAwareLocalScopeProvider {
	
	 @Inject
	 private ResourceDescriptionsProvider resDescProvider;
	
	@Override
	protected IScope getResourceScope(Resource res, EReference reference) {
		new Exception().printStackTrace();
		URI uri = res.getURI();
		System.err.println(uri);
		 IResourceDescriptions index = resDescProvider
                 .getResourceDescriptions(res);
		 System.err.println(index);
         IResourceDescription resourceDescription = index
                 .getResourceDescription(uri);
         System.err.println(resourceDescription);
         System.err.println("=============");
		return super.getResourceScope(res, reference);
	}

}

	@Override
	public void configureIScopeProviderDelegate(com.google.inject.Binder binder) {
		binder.bind(IScopeProvider.class).annotatedWith(Names.named(AbstractDeclarativeScopeProvider.NAMED_DELEGATE)).to(
				MyDslImportedNamespaceAwareLocalScopeProvider.class);
	}
