Currently, the ContextResolvingValve resolves the rootComponentWindow derived from the resolvedSiteMapItem.getHstComponentConfiguration(). Later valves like ComponentRenderingValve, ActionValve or ResourceServingValve might kind of change the context by using a more specific component window (a descendant of rootComponentWindow). This makes it unhandy if you want to inject a valve between the ContextResolvingValve and, say, the ActionValve that requires the real request context instead of the root context set by the ContextResolvingValve. Namely, the root context for an action valve is the component that is referenced for the action
