已选择“dataTableSupUserRoles”。当一个元素被激活时，该按钮应被启用
挑选出来的。调用行选择后的侦听器方法。
在这个方法中，我将“disableNewSupUserRoleButton”设置为true。这也可以工作，但按钮未启用。

您可以更新整个表单，而不是命令按钮 试试这个：
update = "@form"
只是为了测试，请尝试删除立即标记或将值更改为false，如果不起作用，请尝试将ajav事件中的更新代码更改为@formThank，谢谢您的回复！我尝试了你的两个技巧，但仍然不起作用。@hiaslosch17支持bean的范围是什么
@ViewScopedupdate = "@form"
