antd 为什么获取表单数据后，把拿到的values处理了下数据结构，页面的表单就重置了

Question

表单里其它数据都没事，就嵌套结构部分有问题，我感觉是提交时刷新了state，但是不知道怎么解决这个情况呐

<NestedFrom newList={newList} />

const NestedFrom = Form.create({ name: 'registers' })(
    class extends React.Component {
        state = {
            butloading: false,
            stageLists: [],//所属栏目
            catasList: [],//学段
        };
        componentDidMount() {
        }
        //所属栏目
        getstageLists = () => {
            let stageLists = [
                { id: "2", name: "学科资源", code: "xkzy", layer: "1", parentId: "8" },
                { id: "67187239871896512", name: "测试目录1（新）", code: "" }
            ]
            this.setState({
                stageLists
            })
        }
        //提交
        onSubmit = e => {
            e.preventDefault();
            let _this = this;
            _this.setState({
                butloading: true,
            })
            this.props.form.validateFieldsAndScroll((err, values) => {
                if (!err) {
                    console.log(values)
                    let arr = {};
                    arr.rootId = values.rootId;

Answer 1

{getFieldDecorator('resFiles.' + index + '.fileId', {
    initialValue:'', // 表单数值没有回填，设置butloading=false后，页面更新，又刷成默认值了
    rules: [
           {
             required: true,
             message: '请选择学段',
           },
           ],
    })(
       <Cascader placeholder="请选择学段"
