I am new at nativescript and developing programs about a few months. I got same error and I am using radList view and Web image cache plugins. We got an api for sending products and their images and images about 500kb. And I am making tab from their categories and in category i am making a list view for each category and listing products inside it. My code like that;
var tabView = page.getViewById("tabViewContainer");
var meal_list = config.meal_list;
meal_list.forEach(function (item) {
var items = new observable_array_1.ObservableArray();
item.meal_list.forEach(function (item2) {
items.push(new DataItemWithImage(item2.meal_id, item2.meal_name, item2.meal_cost,"http://sezginserpen.com.tr/test_image/" + item2.meal_id + ".jpg"));
// items.push(new DataItemWithImage(item2.meal_id, item2.meal_name, item2.meal_cost,"http://pngimg.com/upload/pizza_PNG7132.png"));
});
var wrapLayout = new wrapLayoutModule.WrapLayout();
var radListView = new listViewModule.RadListView();
var layoutBase = new listViewModule.ListViewGridLayout();
layoutBase.scrollDirection = "Vertical";
layoutBase.spanCount = 2;
wrapLayout.className = "item";
wrapLayout.orientation = "horizontal";
radListView.listViewLayout = layoutBase;
radListView.items = items;//<IC:WebImage stretch="fill" height="250" class="my-image-1" src="{{ image }}></IC:WebImage>
radListView.itemTemplate = '<Border xmlns:IC="nativescript-web-image-cache" borderWidth="0.5" borderColor="lightgray"><stack-layout orientation="vertical" height="250" ><IC:WebImage horizontalAlignment="center" src="{{ image }}"></IC:WebImage><stack-layout width="100%" height="50%"> <label id="product_id_label" text="{{ id }}" style="visibility: collapsed" /><label class="align_center product_label" textWrap="true" text="{{ itemName }}" /> <label class="align_center product_label" textWrap="true" style="color:lightgray" text="{{ itemDescription }}" /> <Border borderWidth="1" borderColor="green" borderRadius="2" style="height:22%;width:95%"> <label tap="add_to_basket" class="align_center" style="background-color:white;color:green;" text="Sepete Ekle" /> </Border> </stack-layout> </stack-layout> </Border>';
wrapLayout.addChild(radListView);
var tabViewItem = new tabViewModule.TabViewItem();
tabViewItem.title = item.category.category_name,
tabViewItem.view = wrapLayout;
var tabView = page.getViewById("tabViewContainer");
tabView.items.push(tabViewItem);
});
AND XML like;
<drawer:rad-side-drawer id="drawer">
<drawer:rad-side-drawer.mainContent>
<!-- Home page contents -->
<stack-layout loaded="contentLoaded">
<TabView id="tabViewContainer" selectedIndex="{{ index }}" selectedColor="#d43b2b" selectedIndexChanged="change" tabsBackgroundColor="#ffffff" >
<TabView.items>
</TabView.items>
</TabView>
</stack-layout>
</drawer:rad-side-drawer.mainContent>
<drawer:rad-side-drawer.drawerContent>
<widgets:drawer-content />
</drawer:rad-side-drawer.drawerContent>
</drawer:rad-side-drawer>
Any idea for what causing this ? And I am using ımagecache but every time got this. And one of my Stack Trace1:

And any idea About how can I catch this types of Error??
Thank you for your helps.
The below-attached example shows, how you could remove tabs from TabView in NativeScirpt for both iOS and Android.
main-page.xml
<Page xmlns="http://schemas.nativescript.org/tns.xsd" navigatingTo="navigatingTo">
<TabView id="tabViewContainer" loaded="tabviewLoaded">
<TabView.items>
<TabViewItem title="">
<TabViewItem.view>
<Label text="This is Label in Tab 1" />
</TabViewItem.view>
</TabViewItem>
<TabViewItem title="">
<TabViewItem.view>
<Label text="This is Label in Tab 2" />
</TabViewItem.view>
</TabViewItem>
</TabView.items>
</TabView>
</Page>
main-page.ts
import { EventData } from "data/observable";
import { Page } from "ui/page";
import {TabView} from "ui/tab-view";
import {isAndroid, isIOS} from "platform"
export function tabviewLoaded(args:EventData){
var tabview =<any> args.object;
if(isAndroid){
var tabViewgrid = tabview._grid;
console.dump(tabViewgrid.removeViewAt(0));
}
if(isIOS){
tabview._ios.tabBar.hidden = true;
}
}
main-page.js
var platform_1 = require("platform");
function tabviewLoaded(args) {
var tabview = args.object;
if (platform_1.isAndroid) {
var tabViewgrid = tabview._grid;
console.dump(tabViewgrid.removeViewAt(0));
}
if (platform_1.isIOS) {
tabview._ios.tabBar.hidden = true;
}
}
exports.tabviewLoaded = tabviewLoaded;
