Question

我有两个ADF面孔表A和B，其rowSelection属性设置为“single”。现在要求是从A中选择一行时，它应清除B中的所有选项，反之亦然。所以我在两个表上都注册了selectionListeners，并且在该方法中执行的代码对未被选中的表执行以下操作：

tablenNotSelected.setSelectedRowKeys(null);

我在这里缺少什么？

Answer 1

您可能需要在桌面或可能的周围容器上设置部分触发器，以实际强制更新屏幕。

Answer 2

不要将所选行键设置为null。而是使用getSelectedRowKeys().RemoveAll(); API。

要刷新其他表格，请执行以下操作。

table_1_selectionListener() {
    RequestContext.getCurrentInstance().addPartialTarget(T2);
}

类似于表2的监听器
