NAppForm pri submite straca hodnoty

Ahojte,
mam nasledovny problem: mam formular s otazkami. Otazok je vela, tak ich chcem zobrazovat na viackrat. Vzdy po submitnuti formulara chcem odpovede ulozit a zobrazit dalsiu sadu otazok. Po kliknuti na tlacidlo submit sa vsak stracaju hodnoty z prvkov vo formulari. Do db sa nic neulozi a po zobrazeni niekolkej sady otazok sa stratia aj hodnoty niektorych hidden poli.
Viete mi poradit, v com je problem?

  public function createComponentSelfForm($name = 'formular')

//nacitanie parametrov
    $formID = $this->getParam('formID');

    $formStatus = 0;

//db:nacitanie povolenych moznosti odpovede pre radioBox
    $values = Forms::fetchQuestOpts($formID);
    foreach ($values as $rec)
    {
      $questOpts[$rec['optID']] = $rec['optText'];
    }

//db:nacitanie otazok

//posun offsetu na dalsiu sadu otazok
