Please tell us how to recreate the issue in as much detail as possible.

I had a ListView which was working properly. After upgrading NativeScript, all items in the list view began rendering as [object object]. I have tried both template and ng-template, since I read that template is deprecated. I reduced the template to a simple Label element with a hard-coded string for the text attribute, and it will show the correct number of elements, but they are still displayed as [object object]. The ios debugger in xcode shows the Label element as a TNSLabel with <empty string> for the text.

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

Template:

    <ListView #quakes_history
        [items]        = "quakes"
        separatorColor = "transparent"
        (itemLoading)  = "onItemLoad($event)" >
        <ng-template let-quake = "item">
                <Label id = "magnitude"
                    text    = "quake.magnitude"
                    class  = "font-xl" >
                </Label>
        </ng-template>
    </ListView>

Code to populate Array:

import { Component }     from "@angular/core";
import { Router     }     from "@angular/router";
import { Page       }     from "ui/page";
import { Quake, quake_list     } from "../../data-types/quake";

@Component ({
    selector    : "quakes-page",
    templateUrl : "pages/quakes/quakes.html",
    styleUrls   : [ "pages/quakes/quakes-common.css", "pages/quakes/quakes.css" ]
})

export class QuakesPage {
    public quakes : Array<Quake> = [];
    
    constructor( private router: Router, private page: Page ) {
        for ( let quake of quake_list.slice() ) {
            this.quakes.push( quake );
        }
    }
}

I needed to import NativeScriptModule and include it in the module imports in my main file. I would like to point out that for something which is apparently necessary for ListView to work, it is very poorly documented. I did not find any reference to it in any of the official examples that I came across.

I also had the same issue, but with the RADLISTVIEW. I solved it importing NativeScriptUIListViewModule in my main module.

import { NativeScriptUIListViewModule } from "nativescript-ui-listview/angular";

@NgModule({
    imports: [
        NativeScriptCommonModule,
        NativeScriptUIListViewModule,
