mvcsitemapprovider Not all configured nodes could be paired with a parent node

I am trying to dynamically create my site map using DynamicNodeProvider Base but I am receiving the following error:

Not all configured nodes could be paired with a parent node. Check your parent keys to ensure that a node with a corresponding key exists in the SiteMap. Note that the match is case sensitive.

SiteMapCacheKey: 'sitemap://localhost/'

Orphaned Nodes:

ParentKey: 'Product' | Controller: 'Products' | Action: 'Product' | Area: '' | URL: '/Products/Product/Product1' | Key: '05633af0-b362-411b-856b-5e16b8ed1fbd' | Source: 'company.infrastructure.ProductsDynamicNodeProvider, project'

The error presents a full list of all my products so I can tell that it is trying to load the full catalog but I am missing a pairing somewhere.

Here is my Mvc.sitemap

<mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0"
            xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0 MvcSiteMapSchema.xsd">

  <mvcSiteMapNode title="Home" controller="Home" action="Index">
    <mvcSiteMapNode title="Products" controller="Products" action="Index">
        <mvcSiteMapNode title="Details" controller="Products" action="Product" dynamicNodeProvider="MWH2.infrastructure.ProductsDynamicNodeProvider, MWH2"/>
    </mvcSiteMapNode>
    <mvcSiteMapNode title="About" controller="Home" action="About"/>
    <mvcSiteMapNode title="Careers" controller="Careers" action="Index"/>
    <mvcSiteMapNode title="Literature" controller="Literature" action="Index"/>
    <mvcSiteMapNode title="Locations" controller="Locations" action="Index"/>
    <mvcSiteMapNode title="Customer Service" controller="Customers" action="Index"/>

    </mvcSiteMapNode>

</mvcSiteMap>

ProductsDynamicNodeProvider.cs

public class ProductsDynamicNodeProvider : DynamicNodeProviderBase
    {
        public override IEnumerable<DynamicNode> GetDynamicNodeCollection(ISiteMapNode node)
        {
            ProductModel model = new ProductModel();   
            using (var prodDB = new MWH2Data())
            {
                model.Product = (from prod in prodDB.Products select prod).ToList(); 
            }

            foreach(var p in model.Product)
            {
                DynamicNode dynamicNode = new DynamicNode();
                dynamicNode.Title = p.ProductName;
                dynamicNode.ParentKey = "Product";
                dynamicNode.RouteValues.Add("id", p.ProductCleanLink);

                yield return dynamicNode;
            }
        }

    }

I have gone over the tutorials and can not find anything relating to parent nodes. Any assistance would be much appreciated.

Recently upgraded site from MVC4 to MVC5 and suddenly encountered this error - everything pointing to "Home" was orphaned.

Cracked open Mvc.sitemap and changed:

<mvcSiteMapNode title="Home" controller="Home" action="Index">

...to:

<mvcSiteMapNode title="Home" controller="Home" action="Index" key="Home">

Problem solved. Most of the time was spent finding this post! Thanks for posting it so long ago. It's still helping. :P

You are specifying "Product" as your parent key, but there are no nodes defined that have "Product" as its key. You need to explicitly set the key of a node somewhere to "Product" so MvcSiteMapProvider knows which parent node they belong to.

<mvcSiteMapNode title="Products" controller="Products" action="Index" key="Product">
