[wijmo-5.20203.766] AutoComplete数据源来自ItemsSourceFunction时

theComboBox.selectedItem拿不到, selectedValu也拿不到, 只有text
let theComboBox = new input.AutoComplete('#theComboBox', {
     displayMemberPath: 'chdh', searchMemberPath: 'chdh', selectedValuePath: 'chdh', headerPath: 'chdh', selectedValue: "001", isRequired: false
    , minLength: 1, async itemsSourceFunction(query, max, callback) {
        const {state, data, msg} = {"data":[{"czy":"张三","chdh":"001","sj":null,"dcck":"上海二号仓","drck":"上海一号仓","id":5,"wfstate":null,"resid":null,"wfid":null}],"state":0};
        if (state === 0) callback(data)
        else layer.alert(msg ? msg : '查询失败')
    }
});

你好，为什么要给itemSourceFunction加async？参考以下代码：

1. import 'bootstrap.css';
   
2. import '@grapecity/wijmo.styles/wijmo.css';
   
3. import './styles.css';
   
4. //
   
5. import * as wijmo from '@grapecity/wijmo';
   
6. import * as input from '@grapecity/wijmo.input';
   
7. //
   
8. document.readyState === 'complete' ? init() : window.onload = init;
   
9. //
   
10. function init() {
    
11.     // AutoComplete with async search using OData source
    
12.     let theAutoComplete = new input.AutoComplete('#theAutoComplete', {
    
13.         displayMemberPath: 'chdh',
    
14.         searchMemberPath: 'chdh',
    
15.         selectedValuePath: 'chdh',
    
16.         headerPath: 'chdh',
    
17.         isRequired: false,
    
18.         minLength: 1,
    
19.         itemsSourceFunction: (query, max, callback) => {
    
20.             const {state, data, msg} = {"data":[{"czy":"张三","chdh":"001","sj":null,"dcck":"上海二号仓","drck":"上海一号仓","id":5,"wfstate":null,"resid":null,"wfid":null}],"state":0};
    
21.             callback(data)
    
22.         },
    
23.         selectedIndexChanged: function () {
    
24.             let product = theAutoComplete.selectedItem;
    
25.             document.querySelector('#msg').textContent = product
    
26.                 ? wijmo.format('{czy} (ID: {chdh})', product)
    
27.                 : 'None';
    
28.         }
    
29.     });
    
30. }
