Description

I created a custom control—nothing too fancy, just a TagButton control—and I binded the ViewModel's Command to it. The root is a ContentPage. In Debug mode, it works well, but in Release, nothing happens.

Here is the XAML code:

<ScrollView
                    HorizontalScrollBarVisibility="Never"
                    Orientation="Horizontal"
                    VerticalScrollBarVisibility="Never"
                    Visual="Default">
                    <HorizontalStackLayout BindableLayout.ItemsSource="{x:Binding FilterCategories, Mode=OneWay}">
                        <BindableLayout.ItemTemplate>
                            <DataTemplate x:DataType="{x:Type localmodel:EnumItem}">
                                <control:FieldTag
                                    Margin="10,0,0,0"
                                    Padding="10,5"
                                    BorderColor="{x:StaticResource PrimaryDark}"
                                    CheckedCommand="{x:Binding Source={x:Reference Root},
                                                               Path=ViewModel.FilterSelectedCommand,
                                                               Mode=OneWay}"
                                    CheckedCommandParameter="{x:Binding .}"
                                    CornerRadius="20"
                                    HasShadow="False"
                                    IsChecked="{x:Binding IsChecked,
                                                          Mode=TwoWay}"
                                    IsCheckedBackgroundColor="{x:StaticResource PrimaryDark}"
                                    IsUnCheckedBackgroundColor="{x:AppThemeBinding Dark=Transparent,
                                                                                   Light={x:StaticResource White}}"
                                    MinimumWidthRequest="80"
                                    Text="{x:Binding DisplayValue,
                                                     Mode=OneTime}"
                                    TextColor="{x:StaticResource Primary}" />
                            </DataTemplate>
                        </BindableLayout.ItemTemplate>
                    </HorizontalStackLayout>
                </ScrollView>

After I changed the Binding to:

CheckedCommand="{x:Binding Source={x:RelativeSource AncestorType={x:Type vm:RouteListViewModel}},
                            Path=FilterSelectedCommand,
                            Mode=OneWay}"

It's now working in both Debug and Release modes.
