Question

我对primefaces dataTable有一点问题，

我在我的表中设置了一个commandButton，以便从表中删除数据

但是当我选择删除一行时，我发现它已经删除了2行而不只是一行

这是我的Bean

        this.setEcole("");
        this.setPromotion(0);
        this.setTypeEcole("");
        this.setTypeEcole("");

    }

    public void onEdit(RowEditEvent event) {
        FacesMessage msg = new FacesMessage("Diplome Edited");
        Integer i = ((Diplome) (event.getObject())).getIdDiplome();
        Diplome d = new Diplome();
        d.setIdDiplome(i);
        d.setEcole(this.getEcole());
        this.UpdateDiplome(d);
        FacesContext.getCurrentInstance().addMessage(null, msg);
        clearForm();
    }

    public void onCancel(RowEditEvent event) {
        FacesMessage msg = new FacesMessage("Diplome Cancelled");

        FacesContext.getCurrentInstance().addMessage(null, msg);
    }

}
