Did my e-mail from almost 15 hours ago not get through to everyone on
the list? :P

To quote myself, "Inject the ComponentSource service, get a page from
it, then get its ComponentResources."

I've got a dedicated service for this, it gets the ComponentResources of
the page you want to link to from the ComponentSource, which has the
added benefit of ensuring that you're linking to a valid page.

Here's the relevant code (for 5.0.18):

  private final ComponentClassResolver componentClassResolver;
  private final ComponentSource componentSource;

  public RedirectServiceImpl(ComponentClassResolver
componentClassResolver, ComponentSource componentSource) {
    this.componentClassResolver = componentClassResolver;
    this.componentSource = componentSource;
  }

  public Link createPageLink(Class<?> pageClass, boolean override,
Object... context) {
    String pageName =
componentClassResolver.resolvePageClassNameToPageName(pageClass.getCanonicalName());
    return
componentSource.getPage(pageName).getComponentResources().createPageLink(pageName,
override, context);
  }

You can, of course, do the same for events etc.
