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.
