Application gets crash when tapping without releasing the finger from the available item and on the empty space of list view.
Exception found from Xcode is as below:
<Warning>: Unhandled managed exception:
Object reference not set to an instance of an object (System.NullReferenceException)
at Xamarin.Forms.Platform.iOS.ContextActionsCell+SelectGestureRecognizer.Tapped (UIKit.UIGestureRecognizer recognizer) [0x00013] in C:\BuildAgent2\work\ca3766cfc22354a1\Xamarin.Forms.Platform.iOS\ContextActionCell.cs:666
at UIKit.UITapGestureRecognizer+Callback.Activated (UIKit.UITapGestureRecognizer sender) [0x00000] in /Users/builder/data/lanes/3969/44931ae8/source/xamarin-macios/src/UIKit/UIGestureRecognizer.cs:211
Adding sample code to re-produce this issue.
Steps to re-produce for attached code:
1. Install the app, and you can see only one cell which has text "notification"
2. Now put one finger on "notification" cell and use another finger to tap on empty cells.
App will get crash immediately with above exception.
Your reproduction is missing. Please attach one when you're able if this is still persisting using the latest stable/prerelease.
Yes, I'm still able to reproduce this issue on latest Xamarin.Forms packages. So it would be great if you fix it as soon as possible.
Again how to reproduce this issue on existing code base:
- Update required packages to latest.
- When you see app running, then put your one finger on TableView Cell which has test "notification". Now without removing first finger tap outside of the list view by putting another finger.
- You will be able to observe the crash.
I hope this will help you.
Do you have the reproduction project to upload? It's still missing.
