如何在使用OData $ expand参数

时将oData服务绑定到SAPUI5表

<Table id="contactPickerTable"
          items="{path: 'modelPersons>/ContactSet',
          filters : [{path : 'Customer',operator : 'EQ',value1:'2035235403'}]
          parameters : {expand:'Address'}}"  
>
.....
<ObjectIdentifier 
      title="{modelPersons>Title}"
      text="{modelPersons>PersonId}" />

我知道列表绑定数据到表的上述示例有效。但是如果我的服务中有$ expand，那么如何在ObjectIdentifier中显示返回集合的属性？我的意思是什么是上下文路径？

服务器响应如下所示：

<entry>
<id></id>
<title type="text">PartnerSet('2010002791')</title>
<updated>2014-05-24T08:05:58Z</updated>
...
<link href="PartnerSet('2010002791')" rel="self" title="Partner"/>
<link href="PartnerSet('2010002791')/Address" rel="http://schemas.microsoft.com/ado/2007/08/dataservices/related/Address" type="application/atom+xml;type=feed" title="Address">

如何访问“姓名”属性？

Answer 1

尝试类似下面的内容，我假设地址有街道，州和国家，我把它们放在$ Select条件下限制返回的字段

<Table id="contactPickerTable"
       items="{
         path: 'modelPersons>/ContactSet',
         filters : [{ path: 'Customer', operator: 'EQ', value1: '2035235403' }]
         parameters: {
           expand: 'Address',
           select: 'Title,PersonId,Address/Street,Address/State,Address/Country'
         } 
       }">
...
<ObjectIdentifier
     title="{modelPersons>Title}"
     text="{modelPersons>PersonId}" />
     <Text
        text="{modelPersons>Address/Street}"/>
     <Text
        text="{modelPersons>Address/State}"/>
     <Text
        text="{modelPersons>Address/Country}"/>
