Hello,
i'm trying to implement the generic language switching as mentioned in
http://wiki.apache.org/lenya/HowToLanguageSwitching at the bottom of the
page. Here's my page2xhtml.xls

Now there's the variable $languages, which should contain the available
languages, but it's empty. Maybe someone has a idea where I have to enable
the function, that this variable will be passed to this file.
(Maybe also someone has implemented this feature already and can post his
xsl
file?)
Thanks in advance
