Carsten, the problem is that there is no code that saves to a file. There should be two choices:
* Saving to a pdf file itself
* Saving to a separate pdf file (according to the pdf spec)
But somebody for some unknown reason implemented writing it in the proprietary format into ~/.kde/share/apps/okular/docdata/ that makes okular unusable for filling forms. Nobody needs the function to save forms under ~/.kde
