我在选择素数面数据表时遇到问题。当我选择任何记录时，我的setter都不会调用。我找到了一些解决方案，比如更改模板或更改为ViewSCope我正在更改所有内容，但仍然不起作用template.xhtml

我的bean（我使用的是Spring），但我必须使用@ViewScope，因为Spring不包含@Scope('view')
// the same annotations in AbstractBean
@Component
@ViewScope //faces bean package
public class TicketBean extends AbstractBean {
... code ...
public TripSchedule getSelectedSchedule() {
return selectedSchedule;
}
public void setSelectedSchedule(TripSchedule selectedSchedule) {
this.selectedSchedule = selectedSchedule;
}
谢谢你的帮助！
我认为您需要向数据表添加一些ajax：
<p:ajax event="rowSelect"/>
<p:ajax event="rowUnselect"/>
