Sorry, for bothering again with a nifty-problem.
The issue is, that I can select Items of ListBoxes, but I don’t see that I selected them until I say:
[java]
nifty.removeScreen(nifty.getCurrentScreen().getScreenId());
[/java]
Then the selected Items are highlighted.

Don’t suppose you have 2 instances of the GUI on screen at the same time by accident ?
Well, I had one, but I removed it with
[java]nifty.removeScreen("Screen");[/java]
