[Bug] [Android] Adding new Cell to existing Table Section causes Java.Lang.IllegalStateException

[drasticactions]

Description

If you have an existing TableSection in a TableView, and invoke adding a new Cell to it (Ex, this.NewTableSection.Add(new TestCell());), the application will throw an Java.Lang.IllegalStateException.

Java.Lang.IllegalStateException: 'The specified child already has a parent. You must call removeView() on the child's parent first.'

This also happens with Xamarin.Forms, so most likely it's an underlying bug that was ported here.

Steps to Reproduce

Run this sample and click Add New Cell.
MauiTableView.zip

Expected Behavior

The new Cell gets added to the Section.

Actual Behavior

The application crashes.

When I delete an item in the list that binding with the listview, it will also show me the same error "The specified child already has a parent. You must call removeView() on the child's parent first".

<ListView x:Name="instrumentsList" ItemsSource="{Binding Instruments}" HeightRequest="200" RowHeight="50"> <ListView.ItemTemplate> <DataTemplate> <ViewCell> <StackLayout Orientation="Horizontal"> <Label Text="{Binding Name}" /> <Label Text="{Binding Size}" /> <Button Text="Delete" Command="{Binding Source={RelativeSource AncestorType={x:Type local:SettingsViewModel}}, Path=DeleteInstrumentCommand}" CommandParameter="{Binding .}" /> </StackLayout> </ViewCell> </DataTemplate> </ListView.ItemTemplate> </ListView>

This looks like it's fixed

I had to modify the code a little bit to set View on TestCell otherwise it crashed with 'ViewCell requires a View`

 this.NewTableSection.Add(new TestCell()
            {
                View = new Label() { Text = "rabbits" }
            });

But otherwise it seems to work now
