PrimeFaces对话框不与数据表

Question

工作我也跟着在这里Demo，但我不知道为什么不工作。我花了3天才解决，但我无法弄清楚我的代码有什么问题。希望有人建议我。

我正在使用Hibernate + JSF 2.0 + PrimeFaces 3.5。

customerBean（RequestScoped）

public class customerBean { 

    private List<Customer> customer; 
    private Customer selectedCustomer; 

    /** Creates a new instance of customerBean */ 
    public customerBean() { 
     customer = new ArrayList<Customer>();   
    } 

    public List<Customer> getCustomer() { 
     CustomersDao cust_dao = new CustomersDao(); 
     customer = cust_dao.findAll();

     return selectedCustomer; 
    } 

    public void setSelectedCustomer(Customer selectedCustomer) { 
     this.selectedCustomer = selectedCustomer; 
    } 
} 

Answer 1

尝试改变变量名称VAR =” 客户 “VALUE =” ＃{customerBean。客户} “

Answer 2

我试过你的代码，它的工作原理。 Debug与FireBug并查看是否有任何错误。

Answer 3

已经测试你的代码，可以确认肯定似乎没有出现任何问题（甚至你可以改进具有独立的形式的话）。在这里你可以找到适合我的SSCCE，自己尝试一下（你应该尽量减少问题的发生，你最好从一些能正常工作的东西开始，并将其适用于具体的情况）。
