xamarin/Xamarin.Forms#10865

please provide a sample. I cannot reproduce that

[angelru]

just add an item to the ObservableCollection, delete and then add another, the problem is when there are 0 items

[AndreiMisiukevich]

just add an item to the ObservableCollection, delete and then add another, the problem is when there are 0 items

So, the test case

1) Exists 1 item in CarouselView 2) I remove this item (Exists 1) 3) I add a new one - crash

Right?

[angelru]

Right

[AndreiMisiukevich]

Right

Just tried. Cannot reproduce on iOS iPhone 11 Simulator.

Here is the stack trace, when I used XF carousel.

And I CANNOT reproduce with the same steps with PanCardView.CarouselView. Are you sure you used mine one?

XF carousel, did you get the exception? I'm sure I used yours too

[AndreiMisiukevich]

XF carousel, did you get the exception? I'm sure I used yours too

No, I tried to reproduce with no luck (XF crashes, Mine -- not). Can you create a small sample?

[angelru]

did you try on android?

[AndreiMisiukevich]

Yes, I did. So can you provide a sample?
