The problem may be with how I'm using the SourcesModule. The SourcesModule has providers that return the Lists based on data that is retrieved after startup, so the Lists cannot be injected. The code snippet is from a separate method that is called after data is loaded and sets the Lists. I'm trying to override the SourcesModule so I can inject mock objects into the Lists.
