Description Erik Renaud 2015-08-26 17:09:25 UTC
Given this xaml:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
        <StackLayout IsVisible="{Binding IsLocked}">
            <Label Text="Admin Unlock Code"/>
            <Entry Text="{Binding AdminUnlockCode}" Keyboard="Numeric" Placeholder="Enter admin unlock code..."></Entry>
            <Button Command="{Binding Unlock}" Text="Unlock"/>
        <StackLayout IsVisible="{Binding IsUnlocked}">
    <ListView ItemsSource="{Binding Items}">
                    <TextCell Text="{Binding Name}" Detail="{Binding Description}" Command="{Binding Execute}" CommandParameter="{Binding ID}"></TextCell>

If I do a Items.Clear() in a Device.BeingExecuteOnMainThread in the Execute command, I get a invalid index error

Hi Erik,

We tried to reproduce your issue on our most recent version of XF and we were unable to get the crash on iOS, Android or wp8, p81, uwp.

If the issue still happen for you, could you please share the minimal project that is sufficient to trigger the issue so we can look at it and fix it ?

Warm regards,

the XF team
