Xamarin.forms: [Bug] [Android] [CollectionView] [SwipeView]

[nschoenberg]

Description

When using SwipeView in a CollectionView it crashs on Android 9.0 (Emulator) throwing System.Reflection.TargetInvocationException.

I've tested different layouts. Setting LeftItems on SwipeView does not have any effects. When using default linear layout without swipe view CollectionView is working as expected.

Steps to Reproduce

1. My Navigation Stack when issue occures:
   /NavigationPage/ContentPage/TabbedPage/

TappedPage has two pages, one of Child-Pages looks like this:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:d="http://xamarin.com/schemas/2014/forms/design"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             mc:Ignorable="d"
             xmlns:prism="http://prismlibrary.com"
             xmlns:viewModels="clr-namespace:Rapport.ViewModels;assembly=Rapport"
             xmlns:models="clr-namespace:Rapport.Data.Models;assembly=Rapport.Data"
             prism:ViewModelLocator.AutowireViewModel="True"
             Title="{Binding Title}"
             Padding="5"
             x:Class="Rapport.Views.OverviewPage">

    <d:ContentPage.BindingContext>
        <viewModels:OverviewPageViewModel />
    </d:ContentPage.BindingContext>

    <ContentPage.Resources>
        <ResourceDictionary>
            <Style TargetType="Label">
                <Setter Property="TextColor" Value="{StaticResource SecondaryTextColor}" />
            </Style>
        </ResourceDictionary>
    </ContentPage.Resources>

    <RefreshView IsRefreshing="{Binding IsRefreshing}" Command="{Binding RefreshCommand}">
        <CollectionView ItemsSource="{Binding TrackedIssues}">
            <CollectionView.ItemsLayout>
                <LinearItemsLayout Orientation="Vertical" ItemSpacing="5"/>
            </CollectionView.ItemsLayout>
            <CollectionView.ItemTemplate>
                <DataTemplate x:DataType="models:IssueModel">
                    <SwipeView>
                        <Label Text="Hello World" />
                    </SwipeView>
                </DataTemplate>
            </CollectionView.ItemTemplate>
        </CollectionView>
    </RefreshView>

</ContentPage>

1. Run Emulator from within Visual Studio 2019
2. Crash

Expected Behavior

View working as expected, showing Collection View

Actual Behavior

Before Page is visible, Exception is thrown and App crashes.

StackTrace:
System.Reflection.TargetInvocationException
Message=Exception has been thrown by the target of an invocation.

Similar thing happening to me when adding a SwipeView in a CollectionView.

the worst thing is that these kind of errors are not correlated to any code line, and you cannot see any exception detail / inner exception:

here the last lines of the output:

[jsuarezruiz]

I have been testing trying to reproduce the problem, but without success.

Attached can find the created example.

Issue9683.zip

@nschoenberg Could you check it to see if something is missing?

[jsuarezruiz]

I just remembered, SwipeView is in Preview and to use it you have to use the experimental flag:

Forms.SetFlags("SwipeView_Experimental");

[nschoenberg]

Uh wow, my fault. Classic RTFM Issue.

Can confirm Forms.SetFlags("SwipeView_Experimental"); in MainActivity solved my issue. Even SwipeView.LeftItems is working now, but hard to handle in TabView because it can happen that user accidentally navigates to another TabItem when opening SwipeView.

@jsuarezruiz This can be closed. But maybe improve Exception to make it more "idiot"proof.

[Licantrop0]

Yeah, I had the flag, but I was setting incorrectly:
instead of:

global::Xamarin.Forms.Forms.SetFlags(
     "CollectionView_Experimental",
     "SwipeView_Experimental");

I was doing:

global::Xamarin.Forms.Forms.SetFlags("CollectionView_Experimental");
global::Xamarin.Forms.Forms.SetFlags("SwipeView_Experimental");

I agree with @nschoenberg that we should open a new one for the very bad exception message: the fact that the exception is not associated to any line of code makes very hard to pinpoint the issue.
