javascript - 过滤 sap.m.List 中的 customListItem

Question

我遇到了一个奇怪的过滤问题。当我使用标准列表项时，以下内容完美运行

new sap.ui.model.Filter(path,operator,value)

但是当我使用 customlistItem 时，它停止工作。我正在使用下面的代码进行过滤。

var list = sap.ui.getCore().byId("listToFilter");
var binding = list.getBinding("items");
var filter = new sap.ui.model.Filter("Description",sap.ui.model.FilterOperator.Contains , value);
binding.filter(filter,"Application"); binding.refresh(true);

我有一个复选框，其文本字段绑定(bind)到我在过滤器路径中传递的属性

var checkBox = new sap.m.CheckBox({                      
                 text: "{Description}",
                 selected:"{path: 'Selected', type:'sap.ui.model.type.String'}"
});

感谢任何有关如何实现这一目标的建议。

I have replicated your scenario and it is perfectly working fine for me.
Below is some sample code.

**view:**
  <List
    headerText="Custom Content"
    id="IDCustomerListItem"
    items = "{oAppView>/modelData}">
    <CustomListItem type="Inactive">
               <CheckBox text="{oAppView>lastName}" selected="true" />
    </CustomListItem>
  </List>

**Controller**:
            var list,
            binding,
            filter;
            list = this.getView().byId("IDCustomerListItem");
            filter = new sap.ui.model.Filter("lastName",sap.ui.model.FilterOperator.Contains , "D");
            binding = list.getBinding("items");
            binding.filter(filter,"Application");
            binding.refresh(true);
