The AbstractDeclaratziveScopeProvider is provided with a delegate socpe
provider, which could be the XbaseScopeProvider.
public void configureIScopeProviderDelegate(com.google.inject.Binder
binder) {
binder.bind(IScopeProvider.class)
.annotatedWith(Names
.named(AbstractDeclarativeScopeProvider.NAMED_DELEGATE))
.to(XbaseScoepProvider.class);
}

org.eclipse.xtext.common.types.util.TypeReferences.getTypeForName(String, Notifier,
JvmTypeReference...)
To use it let TypeReferences be injected into your class.
The notifier needs to be any EObject, Resource or ResourceSet being
(contained in) a correctly configured ResourceSet.

Hello Sven,
Thanks, for your answer, but now I got a stack overflow, because the MyScopeProvider (extends AbstractDeclarativeScopeProvider) has a delegate to the
MyXBaseScopeProvider (extends XBaseScopeProvider) and this gets a delegate to itself.
This happens because both classes has a "@Inject @Named(NAMED_DELEGATE) private IScopeProvider delegate;" in there superclasses, so the
XBaseScopeProvider gets a delegate to itself via this injection.
How should I handle this?
Regards,
Markus

@Victor Mising name:
Thanks for documenting your solution to this. I just updated my Xtext DSL grammar to extend Xbase, which resulted in confusing scoping functionality.
It's been a few years since your post, but I thought I'd bump it to let people know that the issue you ran into still exists (Xtext 2.3.1) and your solution still works!
