Sapui5 设置包含所有关键元素的MultimboBox

我有一个多mbobox，我想用json中的所有键绑定多mbobox。iam使用XML视图。 我需要具有productId、name、category、suppliername等值的MultimboBox。如下所示

我的xml视图是

<MultiComboBox selectionChange="handleSelectionChange" selectionFinish="handleSelectionFinish" width="300px"  
  items="{  
                    path: '/Collection',  
                     sorter: { path: 'Name' }  
                }">  

  <core:Item key="{ProductId}" text="{Name}" />  
        </MultiComboBox> 

我认为，如果不创建新的数据对象（原始对象的键将转换为值），就不可能完成您要求的操作

下面是我将如何做到这一点（尽管我不经常使用xml视图）：

在控制器中，我们创建一个新对象和模型：

var-oModelData={}；
oModelData.data=[]；
for（oData.Collection[0]中的var键）{
var oObj={}；
oObj.value=键；
omodedata.data.push（oObj）；
}
setModel（新的sap.ui.model.json.JSONModel（oModelData））；

下面是一个工作的JSBIN示例：

可能没有抓住要点，但是您发布的原始代码应该可以正常工作。您到底想要什么？

我创建了相同的想法，但我需要在组合框中输入productId、Name、Supplier Name。。。我想要的是这些东西，而不是价值观。@sarathchambayil看看更新后的答案。我不清楚你到底想要什么。很抱歉，我创建了另一个对象，就像你说的那样
