I'm currently in the process of migrating a project from Umbraco v7 to v8.

I'm fairly new to C# so please forgive me if I've missed something very simple!

I've made an attempt to migrate the code - specifically this var from Umbraco v7:

var configNodeId = CurrentPage.GetPropertyValue<int?>("configurationNode", true); 

...replacing the recursive functionality with new fallback option (change below).

There are no console errors on build throughout my solution but I believe this migrated code isn't functioning how it was in v7.

Any thoughts or help would be much appreciated!

namespace PNGBaseUmbracoWebsite.Controllers 
{

public partial class BaseSurfaceController : SurfaceController
{
    public new IPublishedContent CurrentPage
    {
        get { return base.CurrentPage; }
    }

    public IPublishedContent ConfigNode
    {
        get
        {
            // Umbraco 7
            // var configNodeId = CurrentPage.GetPropertyValue<int?>("configurationNode", true); 

            // Umbraco 8
            var configNodeId = CurrentPage.Value<int?>("configurationNode", fallback: Fallback.To(Fallback.Ancestors, Fallback.DefaultValue), defaultValue: null);

            if (configNodeId != null)
            {
                configNode = Umbraco.Content(configNodeId);
            }
        }
    }
}
