Hi,

This is a weird one...

I am using Xamarin Forms and testing on Android only.

I have a TabbedPage with 5 tabs at the bottom, that is hosted inside a NavigationPage.

I have XamDoughnutChart with data that works fine in the first tab. Here is the code:

        <!--DoughnutChart-->
        <ig:XamDoughnutChart SliceClick="DoughnutSliceClicked"
                             AllowSliceExplosion="True"
                             x:Name="doughnutChart"
                             Grid.Row="0"
                             Grid.RowSpan="5"
                             Grid.Column="0"
                             Grid.ColumnSpan="3"
                             AllowSliceSelection="True" >

            <ig:XamDoughnutChart.Series>
                <ig:RingSeries ItemsSource="{Binding Balances, Mode=OneTime}"
                               LabelMemberPath="CurrencyCode"
                               ValueMemberPath="Balance1"
                               LabelsPosition="BestFit"/>
            </ig:XamDoughnutChart.Series>
        </ig:XamDoughnutChart>

Now the when I move to tab 2 3.. and back, no problems. However, when I move to very last tab (5) and back to any other tab, it reaches this (==>) breakpoint only:

        List<Balance> balances;
        public List<Balance> Balances
        {
            get
==>     {
                return balances;
            }
            set
            {
                if (balances != value)
                {
                    balances = value;
                    OnPropertyChanged("Balances");
                }
            }
        }

Now there is only 1 reference to this "Balances" which is when I initially fill it, and there is only 1 binding which I wrote above.

also, the lowercase "balance" still contains the same valid 7 rows of data. So even following this "get" through it should just update.

The last tab is blank as per the code below.

XAML Code in last (5th) tab:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="">xamarin.com/.../forms"
             xmlns:x="">schemas.microsoft.com/.../xaml"
             xmlns:d="">xamarin.com/.../design"
             xmlns:mc="">schemas.openxmlformats.org/.../2006"
             x:Class="Impress.App.Views.More"
          
             Title="More">

</ContentPage>

C# Code

    [XamlCompilation(XamlCompilationOptions.Compile)]
    public partial class More : ContentPage
    {
        public More()
        {
            InitializeComponent();
        }
    }

So the chart becomes blank, and if I tap it, I get a null exception.

As I am writing, I commented out the DoughnutChart code in XAML, and it's not reaching that "get" code anymore, so it's 100% the chart thats calls in after leaving 5th tab.. I suspect there is a bug in the control, as datagrid control on the same page, even with same data is fine.
