Nativescript-ui-feedback: RadListView gave a 'extend of undefined' error

[karl-ford]

Hi there, I am trying to use RadListView in my demo. The issue occured when the code was livesyncing.

RadListView gave a 'extend of undefined' error

Android

• Progress NativeScript UI version: ^3.3.0
• CLI: 3.4.1
• Cross-platform modules: ~3.4.0
• Runtime(s): 3.4.1

1. Start the application
2. add the nativescript-pro-ui through tns add plugin nativescript-pro-ui
3. import NativeScriptUIListViewModule in app.module.ts
4. use RadListView in html
5. run tns debug android
   
   items.component.html

Hey, @karl-ford I tried to reproduce the issue using this demo app but to no avail.

Can you provide a sample project or a Playground demo that can reproduce the issue so we could investigate further

hi @NickIliev !
The whole project is here : Practice APP
I ran it on windows 8.1
Sorry for can't provice a Playground demo, because I am been blocked by the GFW

@karl-ford as you are using Rxjs Observable which loads the data items async I have just introduced the async pipe in the RadListView and the app worked as expected.

<RadListView [items]='items | async'>

However, I was not able to hit the RadListView gave a 'extend of undefined' error so do let me know if you have managed to resolve the issue on your side.

Thanks @NickIliev! I've solved the issue when I updated my nativescript.
I updated it from 3.4.1 to 3.4.2
However, I still don't know what caused the issue.

These errors usually happen when nativescript cli failed to properly add plugin data to platforms folder (when you do a tns plugin install), to correct:

• tns platform remove
• tns platform add
• tns install
• tns run

That solved for me most any ui undefined errors :)
