Hi,

I´m working on an app and I tried to replicated and everything works until my service returns 404 error.

The service throw the exception to ViewModel. The ViewModel throw the exception to View and the View displays the error returned from API.

After that, I swipe down to refresh the page and the code in ViewModel is not executed.

This is the constructor code in View class:
`
public Menu()
{
InitializeComponent();
try
{
this.token = PropertiesOperations.GetTokenProperties();
//show Name
if (this.token.FullName != null)
lblFullName.Text = "Ing. " + this.token.FullName;

            BindingContext = viewModel;
            viewModel = new ProjectViewModel(this.token.UserIDCRM);
        }
        catch (Exception ex)
        {
            Device.BeginInvokeOnMainThread(async () =>
            {
                await this.DisplayAlert("Error", ex.InnerException.Message, "OK");
            });
        }
    }`

This is XAML code:
<StackLayout Orientation="Vertical"> <StackLayout Orientation="Horizontal" Margin="0,0,0,50"> <Label HorizontalTextAlignment="Center" x:Name="lblFullName" HorizontalOptions="CenterAndExpand" FontAttributes="Bold" TextColor="Black" FontSize="16"/> </StackLayout> <ListView x:Name="ProjectsList" ItemsSource="{Binding ProjectsList}" ItemTapped="ListView_ItemTapped" IsPullToRefreshEnabled="true" RefreshCommand="{Binding RefreshCommand}" IsRefreshing="{Binding IsRefreshing}"> <ListView.ItemTemplate> <DataTemplate> <TextCell Text="{Binding idProject}" Detail="{Binding description}" TextColor="Black"></TextCell> </DataTemplate> </ListView.ItemTemplate> </ListView> <ActivityIndicator HorizontalOptions="Center" x:Name="actLoading" IsVisible="{Binding IsRefreshing}" IsRunning="{Binding IsRefreshing}" Color="#1360ad"/> </StackLayout>

It's weird. If the API returns data everything works perfectly.

Have you ever have any situation like this?

Thanks so much!
