我知道这个问题可能会重复，但我真的找不到我的问题的解决方案；我的问题是，除非我在关闭对话框后单击任何行以显示详细信息对话框，否则排序和过滤等数据表功能无法正常工作，所有“排序、过滤”都正常工作并按预期进行。
这是我的代码: Bean.java
@ViewScoped
public class HomeBean implements Serializable {
private List<Ticket> filteredTickets;
private List<Ticket> tickets;
private Ticket selectedTicket;
private Ticket[] selectedTickets;
public HomeBean() {
super();
}
@PostConstruct
public void init() {
getData();
}
private void getData() {
TicketFacade service;
service = TicketFacade.getInstance();
try {
tickets = service.selectTickets();
} catch (Exception e) {
logger.error(Utilities.printStackTrace(e));
}
}
// setter & getters
@PreDestroy
public void finalize() {
logger.debug("@PreDestroy");
}
}

最佳答案
不久前我在屏幕上看到过类似的问题。当页面未完全呈现时，排序和过滤不会发生。出于测试目的，您可以尝试删除 java 脚本并尝试。 另一种调试方法是使用 chrome 按 f12 并查看网络选项卡以查找 ajax 调用。希望这会有所帮助。
关于sorting - Primefaces 数据表排序和过滤在 rowSelect 之前不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16252997/
