Router: Multiple optional parameters support

As a developer I want to have the same view being accessible using different routes with different parameters. For example:

1. /forum/thread/<threadId> opens the thread view
2. /forum/thread/<threadId>/<messageId> opens the same thread view and scrolls to specified message
3. /forum/message/<messageId> – same as above, but retrieves the threadId first, based on messageId

In current implementation we have

@Route(value = FORUM_THREAD_ROUTE /* /forum/thread */, layout = ForumView.class)
@RouteAlias(value = FORUM_MESSAGE_ROUTE /* /forum/message */, layout = ForumView.class)

and then

	@Override
	public void setParameter(BeforeEvent event, @WildcardParameter String parameter) {
		if(StringUtils.isNotEmpty(parameter)) {
			if (event.getLocation().getPath().startsWith(FORUM_THREAD_ROUTE)) {
				String[] segments = parameter.split("/");
				if (segments.length >= 1) threadIdParam = segments[0];
				if (segments.length >= 2) messageIdParam = segments[1];
			} else {
				String[] segments = parameter.split("/");
				if (segments.length >= 1) messageIdParam = segments[0];
			}
		}
	}

Yeah, that’s me, the OP
