RadListView Error

[Stan]

I'm new to NativeScript and I'm trying out RadListView but I'm getting an "Error: A Frame must be used to navigate to a page". 
I copied & pasted the code from https://www.nativescript.org/blog/a-deep-dive-into-telerik-ui-for-nativescripts-listview and only took out the CSS references.

main-page.xml
<Page xmlns="http://schemas.nativescript.org/tns.xsd" xmlns:lv="nativescript-telerik-ui/listview" loaded="pageLoaded">

    <lv:RadListView id="listview"> 
        <lv:RadListView.listViewLayout>
            <lv:ListViewLinearLayout scrollDirection="Vertical"/>
        </lv:RadListView.listViewLayout>
        <lv:RadListView.itemTemplate>
            <StackLayout>
                <Label text="{{ itemName }}" />
                <Label text="{{ itemDesc }}" textWrap="true" />
            </StackLayout>
        </lv:RadListView.itemTemplate>
    </lv:RadListView>

</Page>

main-page.js
var listview = require("nativescript-telerik-ui/listview");
var view = require("ui/core/view");

exports.pageLoaded = function(args) {
    var items = [];
    items.push(
        {
            itemName: "Arcade Fire",
            itemDesc: "Funeral"
        },
        {
            itemName: "Bon Iver",
            itemDesc: "For Emma, Forever Ago"
        },
        {
            itemName: "Daft Punk",
            itemDesc: "Random Access Memories"
        },
        {
            itemName: "Elbow",
            itemDesc: "Build a Rocket Boys!"
        }
    )
    var page = args.object;
    var listview = view.getViewById(page, "listview");
    listview.items = items;
}

Any ideas on what I'm missing?

Hello,
First of all, thank you for your interest in UI for NativeScript.

I reviewed the below-attached code and tested on my side, however, was unable to reproduce this error.
For your convenience, I am attaching the sample project, which I used for testing.
Regarding that, could you provide some more info about your environment(NativeScript CLI, -core-modules, node versions)?   It would also help if you could also send us sample project, where the problem could be reproduced.

Thank you so much for the zip file with the working code!

With the files you sent I was able to trace what was wrong. Somehow my project app.js file had the old format giving me the error, it works find now with your file. Thanks again!

OLD:

var application = require("application");
application.mainModule = "main-page";
application.cssFile = "app.css";
application.start();

NEW:

require("./bundle-config");
var application = require("application");

application.start({ moduleName: "main-page" });

Can RadListView use multiple templates like the regular ListView? thanks again

[Nikolay Tsonev]

Hi,
At this time in the RadListView could be used only one template, however, we have already logged this as a feature request in our --feedback repository.

For further info about the feature, you could keep track on this issue here.

Let me know if I could assist you further

Thank you for that info Nikolay, I will track the new feature.

In the meantime, can the core-ListView scroll horizontal or is that only available in RadListView?

[Nikolay Tsonev]

Hello Stan,

Thank you for writing us back 
Unfortunately, horizontal scroll functionality is supported only from the RadListView component.
However, the multiple templates feature is already planned for the upcoming release of UI for NativeScript as it is mentioned in the issue and will be available soon. 

Let me know if I could assist you further
