ok, this sounds really not that clean. ;-)

aah, i see. i have to give the objects to a viewhelper and get the needed
infotmation return. great!

this is something you can discuss. i in the beginning designed n:1, but
wanted to be a little bit more flexible... i have got this feeling, that
there will be at least one further type that can then be added to a
download in addition...

yes, this would then be less complicated.

kind regards.
