FarCry - navigation in a multi language site

This could be solved in different ways. One could make three different page templates calling the three different language navigations - or one could make categories for each of the languages and make pages belong to one of these.

However we wanted to have only one template, and not to have categories. We wanted to sort it with three different top nodes in the site tree. Looking like this:

Then we gave aliases to these three navigation nodes.

We then made a new method in a utilities cfc we use in our company, and call it like this from out header template (before the navigation section):

The method then checks if the current page, or any of it's ancestors have an alias of one of those provided with the cfinvokeargument. It then returns the alias, and we can make the navigation like so:

Here's the code for the method (first version - it still needs some work):

By doing it this way we have a reusable way of handling this, without the hassle of managing several very similar templates, and with a very intuitive grouping of the different articles in the site tree.
