That’s my entity for JPA

    @Column(name = "password", nullable = false, length = 255)
    @NotNull(message = "Required.")
    private String password;

@Transient
    private String confirm;

Here i creat my form

    public ItemEditor(EntityItem<T> item, Object[] visibleFields) {

        this.item = item;
        this.entityClass = (Class<T>) item.getEntity().getClass();
        form = new Form();
        form.setBuffered(true);
        form.setImmediate(true);
        form.setFormFieldFactory(new CSFieldFactory());
        form.setItemDataSource(item, Arrays.asList(visibleFields));
....

but i see only single password field. What is wrong?
