Strange error in SfListView ItemSource after upgrade to 19.1.0.69

[jose luis barajas]

Hi

Today I upgrade to ver 19.1.0.69 and suddenly ocurrs one bug in my program filling an ObservableCollection with binding ItemSource to one SfListView

My XAML

...

    <ContentView.Content>

        <Grid  x:Name="GridProgramados" >

            <sync:SfListView x:Name="lstProgramados" 

                                         ItemsSource="{Binding ListaProgramados, Mode=TwoWay}" 

                                         SelectionMode="None"

                                         SelectionGesture="Tap"

                                         ItemSpacing="0,5,0,5" 

                                         AutoFitMode="DynamicHeight">

                <sync:SfListView.ItemTemplate>

                    <DataTemplate x:Name="ItemTemplate1">

                        <Grid HorizontalOptions="FillAndExpand">

                            <Grid.RowDefinitions>

                                <RowDefinition Height="*"/>

                            </Grid.RowDefinitions>

                            

                            <Grid.ColumnDefinitions>

                                <ColumnDefinition Width="2"/>

                                <ColumnDefinition Width="*"/>

                            </Grid.ColumnDefinitions>

...

The error is:

Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

The code that fills this collection is:

...

          private ObservableCollection<TarjetaInfo> _listaProgramados = new ObservableCollection<TarjetaInfo>();

...

            var tarjetas = await LoadData();

            var tListaProgramados = tarjetas.Where(x => x.Estatus == ESTATUS.INCIALES.ToString());

            ListaProgramados = new ObservableCollection<TarjetaInfo>(tListaProgramados.ToList());

For testing purposes if comment the line in bold in the following property, the program fills the collection fine, or comment xaml code, whatever!

        public ObservableCollection<TarjetaInfo> ListaProgramados

        {

            get => _listaProgramados;

            set

            {

                _listaProgramados = value;

                //OnPropertyChanged(); 

            }

        }

Returning to version 19.1.0.63, my program runs fine!

Please help!
