```auto
var example = Observable("");

```

```auto
    <Panel ux:Class="Example" Name="self">
        <string ux:Property="Value" ux:Value="" />
        <TextEdit Value="{Property self.Value}" />
    </Panel>

```

```auto
<Example Value="{example}" />

```

In local preview I had no problem, but in Android I got this error:

ERROR: Object reference was null Uno.NullReferenceException occured.

Hi!

Thanks for reporting, I have filed a ticket for this issue 🙂 This code works if you compile for Android, so `uno build -t=android -r` should work for you if you need a workaround in the meantime
