DDS Delete property in nested type error

Hi!

I have a model within a model wich is working fine until I delete public property from the nested model. This generates server error when saving it to the store. 

Shouldn't the class attribute handle cases like that?

Is there a way of manually mapping a nested model like that?

[EPiServerDataStore(AutomaticallyCreateStore = true, AutomaticallyRemapStore = true)]
public class ConfigurationItemDataModel
{
    [EPiServerDataIndex] public Identity Id { get; set; }
    public ConfigDataModel BasicConfig { get; set; }
}

The nested model:

[EPiServerDataStore(AutomaticallyCreateStore = true, AutomaticallyRemapStore = true)]
public class ConfigDataModel
{
    [JsonIgnore] [EPiServerDataIndex] public Identity Id { get; set; }
    [JsonProperty ( "title" )] public string Title { get; set; }
    [JsonProperty ( "baseUrl" )] public string BaseUrl { get; set; }
    [JsonProperty ( "imageUrl" )] public string BackgroundImageUrl { get; set; } // <-- the deleted property
}

And the saving:

public ConfigurationItemViewModel SaveConfiguration ( ConfigurationItemDataModel data ) 
{
    using ( var store = DynamicDataStoreFactory.Instance.GetOrCreateStore ( typeof ( ConfigurationItemDataModel ) ) )
    {
    var existingItem = store.Items<ConfigurationItemDataModel> ()
        .FirstOrDefault ( m => m.Id.StoreId == data.Id );

    if ( existingItem != null )
    {
        data.Id = existingItem.Id;
        data.BasicConfig.Id = existingItem.BasicConfig.Id;
    }
    //Here be errors:
    store.Save ( data );

    return data;
    }
}

And it all works great, but when I delete property from the nested model(ConfigDataModel), then Episerver does not know what to do at Save() and throws this error:

Server Error in '/' Application.

Right, so I have figured out some solution. I hope it is the right way, because I have no idea how all of this works. Documentation is out of date.

    public class Patcher
    {
        public static string[] oldNames = new string[2]{ "oldProperty1", "oldPropert2"};

        public static void Patch()
        {
            using ( var store = DynamicDataStoreFactory.Instance.GetStore( typeof ( ConfigDataModel ) ) )
            {
                var item = store?.StoreDefinition.AllMappings.FirstOrDefault ( x => oldNames.Contains(x.PropertyName) );
                if (item == null)
                    return;

                store.StoreDefinition.Remap ( typeof ( ConfigDataModel ) );
                store.StoreDefinition.CommitChanges ();

            }
        }
    }

I think that nested type is not flaged to be mapped, only the top type is. So I needed to call Remap manually in one of my services implementing [InitializableModule].
