Question

我想在表格的元素之后更新Button“buttonEditRole” 选择了“dataTableSupUserRoles”。当元素为
时，该按钮应该被启用选择。调用行选择后的监听器方法在这个方法中，我将“disableNewSupUserRoleButton”设置为true。这也有效，但按钮无法启用这是我的xhtml：

听众方法：

public void onSupplierUserRoleRowSelect(SelectEvent e){

    this.disableSupUserRoleButtons=false;
}

Answer 1

试试这个：

update = "@form"

JSF Primefaces Commandbutton没有更新AJAX
