Hi,

I'm trying to get outline view to work in Theia with my language server (I'm using LSP4J). I am returning a single test-DocumentSymbol in the method `public CompletableFuture<List<Either<SymbolInformation, DocumentSymbol>>> documentSymbol(DocumentSymbolParams params)` of TextDocumentService. The method is called, however Theia does show "No outline information available." in the outline view.

Any ideas on how to fix that? Which attributes do I need to set on DocumentSymbol in order for it to show up in the outline?

Cheers,

Julian
