JSF2 (and Primefaces): Form for fileupload within another “normal” form, howto do this?

This makes honestly no sense. I'm not sure how you come up to this conclusion. Perhaps you concluded this based on an incorrect observation of a problem.

Perhaps you used the wrong bean scope and encountered null values for all so far entered input and previously uploaded files while processing the form submit. You should be using ViewScoped if you want the very same bean instance to live as long as you're interacting with the same view by several ajax requests.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
