jsf h：dataTable - 删除行后不刷新

Question

Hello Guys我需要你的帮助照常

Jsf h：dataTable - 删除行后不刷新。

直到我必须重新启动程序。

我该怎么办才能解决这个问题？

谢谢约翰。

ManagedBean

public List<Customer> getCustomerList() {

    if (customerList == null) {

        customerList = new ArrayList<Customer>(bookstoreManager.getAllCustomers());

        for (Customer cus : customerList) {
            System.out.println("Hello" + cus.getFirstName() + "......." + cus.getLastName());
        }
   }

    return customerList;
}

Business Logik

public List<Customer> getAllCustomers() {

    TypedQuery<Customer> query = em.createQuery("Select c from Customer c", Customer.class);

    return query.getResultList();
}
