how to reset primefaces wizard's steps?

i use primefaces `<p:wizard>` and i registiration step by step.if registiration is end succesfully,wizard's step is first but if i go on for new record or user,Wizard can not add new record.İt is updating previous record/user instead.How do I add new records in series? Another problem; when it returned to the first step,it can not to reset the field.how can i do that? its submit button's code; ``` <p:commandButton immediate="true" value="Submit" update="@parent,wiz1,growl,panel" actionListener="#{OgrenciKayit.save}" oncomplete="wiz.loadStep (wiz.cfg.steps [0], true)" /> ``` its returned to the first step if wizard submitted. ``` oncomplete="wiz.loadStep (wiz.cfg.steps [0], true)" ``` and actionListener ``` public void save(ActionEvent actionEvent) { tx = session.beginTransaction(); session.save(ogrenci); tx.commit(); FacesMessage msg = new FacesMessage("Başarılı", "Hoşgeldin :" + ogrenci.getAd()); FacesContext.getCurrentInstance().addMessage(null, msg); } ``` Waiting for your ideas..
