[Mediawiki-l] Display category name on article page

[orschiro at googlemail.com]

Hello guys,

all I want to do is to display an alternative category name on an
article page. I included the following:

[[Kategorie:A1:Kapitel 3|Kapitel 3]]

But instead of displaying Kapitel 3 he shows me A1:Kapitel 3. Why
doesn't this work?

Thank you in advance.

Regards
