In the default Riot project setup there a two different DispatcherServlets. One that handles public request (usually mapped to *.html) and another one that provides the Riot admin user-interface (mapped to /riot/*).

When working with components, the Riot servlet needs to access some of the beans defined in the website-servlet's context. More precisely it needs to look up all ComponentListControllers and of course the ComponentRepository. Additionally it must obtain a reference to the website's cache instance in order to invalidate cache items when components are published.
