A very hacky workaround for the "Index pages" issue. see http://tynamo.org/tapestry-routing+guide#tapestry-routingguide-IndexPages

		configuration.add("MyRootDispatcher", new Dispatcher() {
			@Override
			public boolean dispatch(Request request, Response response) throws IOException {

				// The extended name may include a page activation context. The trick is
				// to figure out where the logical page name stops and where the
				// activation context begins. Further, strip out the leading slash.

				boolean hasAppFolder = applicationFolder.equals("");
				String applicationFolderPrefix = hasAppFolder ? null : "/" + applicationFolder;

				String path = request.getPath();

				if (applicationFolderPrefix != null) {
					int prefixLength = applicationFolderPrefix.length();

					assert path.substring(0, prefixLength).equalsIgnoreCase(applicationFolderPrefix);

					// This checks that the character after the prefix is a slash ... the extra complexity
					// only seems to occur in Selenium. There's some ambiguity about what to do with a request for
					// the application folder that doesn't end with a slash. Manuyal with Chrome and IE 8 shows that such
					// requests are passed through with a training slash,  automated testing with Selenium and FireFox
					// can include requests for the folder without the trailing slash.

					assert path.length() <= prefixLength || path.charAt(prefixLength) == '/';

					// Strip off the folder prefix (i.e., "/foldername"), leaving the rest of the path (i.e., "/en/pagename").

					path = path.substring(prefixLength);
				}


				// TAPESTRY-1343: Sometimes path is the empty string (it should always be at least a slash,
				// but Tomcat may return the empty string for a root context request).

				String extendedName = path.length() == 0 ? path : path.substring(1);

				// Ignore trailing slashes in the path.
				while (extendedName.endsWith("/")) {
					extendedName = extendedName.substring(0, extendedName.length() - 1);
				}

				if (componentClassResolver.isPageName(extendedName)) {
					String canonicalized = componentClassResolver.canonicalizePageName(extendedName);

					boolean loopback = request.getParameter(TapestryConstants.PAGE_LOOPBACK_PARAMETER_NAME) != null;

					PageRenderRequestParameters parameters = new PageRenderRequestParameters(canonicalized, EMPTY_CONTEXT, loopback);

					componentRequestHandler.handlePageRender(parameters);
					return true;
				}

				return false;
			}
		}, "after:*");
	}

}

This module accomplishes three things:

• The default PageRenderDispatcher will skip Index pages.
• There is a new Dispatcher that will deal with the Index pages but it's configured after all the other dispatchers with "after:*"
• This new Dispatcher mandates that Index pages MUST NOT have a context. It forces EMPTY_CONTEXT on all the Index pages.

This is really really hacky code, but somehow very useful.
