Build Identifier: 2.3.0

if one customized IDefaultResourceDescriptionStrategy this changes will not be reflected in the local resource since scoping uses 

org.eclipse.xtext.scoping.impl.ImportedNamespaceAwareLocalScopeProvider.internalGetAllDescriptions(Resource)

which calls Scopes.scopedElementsFor(allContents, qualifiedNameProvider)

=> you have to customize the ImportedNamespaceAwareLocalScopeProvider too
if you e.g. add user data to the index.

it would be nice to have a default/optional shipped implementation that does this out of the box e.g.


@Inject
	private IDefaultResourceDescriptionStrategy rds;
	
	@Override
	protected ISelectable internalGetAllDescriptions(final Resource resource) {
		Iterable<EObject> allContents = new Iterable<EObject>(){
			public Iterator<EObject> iterator() {
				return EcoreUtil.getAllContents(resource, false);
			}
		}; 
		final List<IEObjectDescription> allDescriptions = new ArrayList<IEObjectDescription>();
		IAcceptor<IEObjectDescription> acceptor = new IAcceptor<IEObjectDescription>() {
			
			@Override
			public void accept(IEObjectDescription t) {
				allDescriptions.add(t);
			}
		};
		for (EObject o : allContents) {
			rds.createEObjectDescriptions(o, acceptor);
		}
		return new MultimapBasedSelectable(allDescriptions);
	}


Reproducible: Always
