@maikenmadsen1992 When trying your playground it errors out because the ObservableArray has not been imported. After importing it, it runs fine, but I can't see any tabs in the code. Can you confirm you've linked the correct playground?

[maikenmadsen1992]

I have updated the playground link, i'm so sorry I uploaded something wrong :-S

[maikenmadsen1992]

I have also made another playground with a much simpler example: https://play.nativescript.org/?template=play-vue&id=7hhWp4&v=2

When the user press the button the listView have to update and show the new data without having to press tab 2 and back to tab 1.

If you enable logs in app.js, you can see

ERROR: [Vue warn]: Property or method "selectedIndex" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

---> <HelloWorld>
<Frame>
<Root>

If I change

 <TabView :selectedIndex="selectedIndex" @selectedIndexChange="indexChange">

to just

 <TabView>

It works as expected.
