Question

hi i need List grouping control by using js view.but openui5 provides code by using xml view.
https://openui5.hana.ondemand.com/explored.html#/sample/sap.m.sample.ListGrouping/preview
how to convert this code into js view and how to make ListGrouping able to selection for both element level and group level and change this as dropdown box
List.view.xml
<mvc:View
controllerName="sap.m.sample.ListGrouping.List"
xmlns:l="sap.ui.layout"
xmlns:mvc="sap.ui.core.mvc"
xmlns="sap.m">
<List
items="{
path: '/ProductCollection',
sorter: {
path: 'SupplierName',
descending: false,
group: true
},
groupHeaderFactory: '.getGroupHeader'
}"
headerText="Products" >
<StandardListItem
title="{Name}"
description="{ProductId}"
icon="{ProductPicUrl}"
iconDensityAware="false"
iconInset="false" />
</List>
</mvc:View>
List.controller.js
sap.ui.define([
'jquery.sap.global',
'sap/m/GroupHeaderListItem',
'sap/ui/core/mvc/Controller',
'sap/ui/model/json/JSONModel'
], function(jQuery, GroupHeaderListItem, Controller, JSONModel) {
"use strict";
var ListController = Controller.extend("sap.m.sample.ListGrouping.List", {
onInit : function (evt) {
// set explored app's demo model on this sample
var oModel = new JSONModel(jQuery.sap.getModulePath("sap.ui.demo.mock", "/products.json"));
this.getView().setModel(oModel);
},
getGroupHeader: function (oGroup){
return new GroupHeaderListItem( {
title: oGroup.key,
upperCase: false
} );
}
});
return ListController;
});
how to write the same code by using js view
I have tried like as follows, but i am getting Error: Missing template or factory function for aggregation items of Element sap.m.List#__list0 !
List.view.js
sap.ui.jsview("oui5mvc.List", {
getControllerName : function() {
return "oui5mvc.List";
},
createContent : function(oController) {
odbbshiftGlobalId = this.getId();
var oMyFlexbox = new sap.m.FlexBox({
items: [
oList = new sap.m.List({
width: '500px',
group: true,
groupHeaderFactory: '.getGroupHeader',
items: [
]
}),
]
});
oMyFlexbox.placeAt(this.getId()).addStyleClass("tes");
}
});
List.controller.js
sap.ui.controller("oui5mvc.List", {
onInit: function() {
var data = {

Answer 1

Your call to bind items to the list is not entirely correct.
The method takes an object with binding information as parameter instead of just the path to the model property. See the documentation for bindItems and bindAggregation in general.
In your case it should look like
oList.bindItems({
path: "/ProductCollection",
template: new sap.m.StandardListItem({
title: "{Name}",
description: "{ProductId}",
icon: "{ProductPicUrl}"
})
});
