XAML / Self binding, bindingcontext

Hello,

I want to bind the text property of a editor element to BindableProperty. Here is what I tried:

MyForm.xaml

<?xml version="1.0" encoding="UTF-8"?>
<ContentPage x:Class="Com.Acme.MyForm"
                        xmlns="http://xamarin.com/schemas/2014/forms"
                        xmlns:local="clr-namespace:Com.Acme;assembly=Com.Acme"
                        xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
                        >

    <ContentPage.Content>
        <Grid>
            <Label Text="1" />
            <Editor BindingContext="{local:MyForm}" Grid.Column="1" Text="{Binding Path=MyProperty}" />
        </Grid>
    </ContentPage.Content>
</ContentPage>

MyForm.cs

namespace Com.Acme {

public partial class MyForm : ContentPage {

    public static readonly BindableProperty MyPropertyProperty = BindableProperty.Create(
                                                                "MyProperty",
                                                                typeof(Object),
                                                                typeof(MyForm),
                                                                null,
                                                                BindingMode.TwoWay,
                                                                null,
                                                                null,
                                                                null,
                                                                null,
                                                                null
                                                            );

    public MyForm () {
        InitializeComponent ();
    }

    public Object MyProperty {

        get { return GetValue (MyPropertyProperty); }
        set { SetValue(MyPropertyProperty, value); }

    }

}

While the code above is running, I see around 60 block of this exception (all are different but similar) in Application Output panel and application exits in emulator:

Where am I doing something wrong?

Well... I solved it. I'm writing the solution here.

First, I set the name of content page by x:Name directive and removed imported local namespace:

<?xml version="1.0" encoding="UTF-8"?>
<ContentPage x:Class="Com.Acme.MyForm"
             x:Name="xMyForm"
             xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             >
             ...

then I changed BindingContext property as below:

...
<Editor BindingContext="{x:Reference Name=xMyForm}" Grid.Column="1" Text="{Binding Path=MyProperty}" />
...

now MyProperty value appears in the editor.
