I have implemented my own ScopeProvider for my grammar.
But somehow I am not able to integrate it streamlining with the stubs generated be Xtext

The stub is GeneratorModelScopeProvider(package omitted)
it is an AbstractGeneratorModelScopeProvider which in turn is an
DelegatingScopeProvider.

During debugging I recognized that the ScopeProvider is instantiated over and over again. Which surprise me. because I thought this instance could be reused for the whole runtime.

I suffered some NullPointerExeptions because one delegate in the generated stub does not get set as it should be.

I guess I only need to Guice annotate my ScopeProvider in the right way and the problem is solved.

which delegate do you mean and what are you doing

the normal delegating scopeprovider is bound by
public void configureIScopeProviderDelegate(Binder binder) {
binder.bind(IScopeProvider.class).annotatedWith(Names.named(AbstractDeclarativeScopeProvider.NAMED_DELEGATE)).to(ImportedNamespaceAwareLocalScopeProvider.class);
}

in AbstractMyDslRuntimeModule
