Thank you Hannes,
I've got only one action because I only have a list view with one selected and shown entry(If not manually selected the first of the category). I've also checked that any param is maped in RealURL. If I wouldn't use the redirect  I would have two URL category/categoryname.html
and entry/nameOfTheFirstCategoryEntry.html. Through the redirect I've got only the second one.
