sapui5列表中的数据绑定未提供任何数据

Question

每次在sapui5列表中显示JSON数据时，我的问题都会不断出现。

我没有收到数据。

我将为计算字段添加扩展语法 <data-sap-ui-xx-bindingSyntax="complex">，但没有结果， 所以我有一个JSON文件，带有nam发票和包含列表的XML视图。

<mvc:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m" controllerName="tmp.Zprojetyoussra.controller.InvoiceList"
	xmlns:html="http://www.w3.org/1999/xhtml">
<List
		headerText="invoiceListTitle"
		class="sapUiResponsiveMargin"
		width="auto"
		items="{invoice>/Invoices}">
		<items>
			<ObjectListItem
				title="{invoice>Quantity} x {invoice>ProductName}"/>
		</items>
	</List>
</mvc:View>

{
  "Invoices": [
	{
	  "ProductName": "Pineapple",
	  "Quantity": 21,
	  "ExtendedPrice": 87.2000,
	  "ShipperName": "Fun Inc.",
	  "ShippedDate": "2015-04-01T00:00:00",
	  "Status": "A"
	},
	{
	  "ProductName": "Milk",

	  "ExtendedPrice": 9.99999,
	  "ShipperName": "ACME",
	  "ShippedDate": "2015-02-18T00:00:00",

	},
	{

	  "Quantity": 3,
	  "ExtendedPrice": 6.85000,
	  "ShipperName": "ACME",

	  "ExtendedPrice": 8.8000,
	  "ShipperName": "ACME",

  ]
