我無法從View中的bean中查看範圍內的表中選擇的值。 以下代碼不起作用，但在我使用會話或請求範圍時起作用。@ViewScope不能與primefaces一起工作<p:ajax>
這裏是我的JSF頁面：

@ManagedBean
@ViewScoped
public class Prime implements Serializable {
ArrayList<UIData> list = new ArrayList<UIData>();
private UIData selected;
private UIDataModel listModel;
private String testVaue;
private ArrayList<String> tmp = new ArrayList<String>();

private boolean toggle1 = true;
public Prime() {
for (int k = 1; k < 3; k++) {
UIData model =new UIData(""+k, ""+k);
list.add(model);
}
listModel = new UIDataModel(list);
}
public void onRowSelect(SelectEvent event) {
try{
System.out.println("Sellected Value : "+((UIData)event.getObject()).getNumber());
}catch (Exception e) {
e.printStackTrace();
}
}
// Getters and setters.
